We don’t yet know how bad the coronavirus outbreak will be in America.  But we do know that the virus is likely to have a major impact on Americans’ access to medication.  Currently, 80% of the active ingredients found in the drugs Americans take are made in China, and the virus has disrupted China’s ability to manufacture and supply those ingredients.  Generic drugs, which comprise 90% of America’s drugs, are likely to be particularly impacted because most generics are made in India, and Indian drug makers rely heavily on Chinese-made ingredients.  Indeed, on Tuesday, March 3, India decided to restrict exports of 26 drugs and drug ingredients because of reductions in China’s supply.  This disruption to the generic supply chain could mean that millions of Americans will not get the drugs they need to stay alive and healthy.

Coronavirus-related shortages are only the latest in a series of problems recently afflicting the generic drug industry.  In the last few years, there have been many reports of safety issues affecting generic drug quality at both domestic and overseas manufacturing facilities.  Numerous studies have uncovered shady practices and quality defects, including generics contaminated with carcinogens, drugs in which the active ingredients were switched for ineffective or unsafe alternatives, and manufacturing facilities that falsify or destroy documents to conceal their misdeeds.

We’ve also been inundated with stories of generic drug makers hiking prices for their products.  Although, as a whole, generic drugs are much cheaper than innovative brand products, the prices for many generic drugs are on the increase.  For some generics – Martin Shkreli’s Daraprim, heart medication Digoxin, antibiotic Doxycycline, insulin, and many others – prices have increased by several hundred percent. It turns out that many of the price increases are the result of anticompetitive behavior in the generic market. For others, the price increases are due to the increasing difficulty of generic drug makers to earn profits selling low-priced drugs.

Even before the coronavirus outbreak, there were numerous instances of shortages for critical generic drugs.  These shortages often result from drug makers’ lack of incentive to manufacture low-priced drugs that don’t earn much profit. The shortages have been growing in frequency and duration in recent years.  As a result of the shortages, 90 percent of U.S. hospitals report having to find alternative drug therapies, costing patients and hospitals over $400 million last year.  In other unfortunate situations, reasonable alternatives simply are not available and patients suffer.

With generic drug makers’ growing list of problems, many policy makers have called for significant changes to America’s approach to the generic drug industry. Perhaps the FDA needs to increase its inspection of overseas facilities?  Perhaps the FTC and state and federal prosecutors should step up their investigations and enforcement actions against anticompetitive behavior in the industry? Perhaps FDA should do even more to promote generic competition by expediting generic approvals

While these actions and other proposals could certainly help, none are aimed at resolving more than one or two of the significant problems vexing the industry. Senator Elizabeth Warren has proposed a more substantial overhaul that would bring the U.S. government into the generic-drug-making business. Under Warren’s plan, the Department of Health and Human Services (HHS) would manufacture or contract for the manufacture of drugs to be sold at lower prices.  Nationalizing the generic drug industry in this way would make the inspection of manufacturing facilities much easier and could ideally eliminate drug shortages.  In January, California’s governor proposed a similar system under which the state would begin manufacturing or contracting to manufacture generic drugs.

However, critics of public manufacturing argue that manufacturing and distribution infrastructure would be extremely costly to set up, with taxpayers footing the bill.  And even after the initial set-up, market dynamics that affect costs, such as increasing raw material costs or supply chain disruptions, would also mean greater costs for taxpayers.  Moreover, by removing the profit incentive created under the Hatch-Waxman Act to develop and manufacture generic drugs, it’s not clear that governments could develop or manufacture a sufficient supply of generics (consider the difference in efficiency between the U.S. Postal Service and either UPS or FedEx).

Another approach might be to treat the generic drug industry as a regulated industry. This model has been applied to utilities in the past when unregulated private ownership of utility infrastructure could not provide sufficient supply to meet consumer need, address market failures, or prevent the abuse of monopoly power.  Similarly, consumers’ need for safe and affordable medicines, market failures inherent throughout the industry, and industry consolidation that could give rise to market power suggest the regulated model might work well for generic drugs.   

Under this approach, Hatch-Waxman incentives could remain in place, granting the first generic drug an exclusivity period during which it could earn significant profits for the generic drug maker.  But when the exclusivity period ends, an agency like HHS would assign manufacturing responsibility for a particular drug to a handful of generic drug makers wishing to market in the U.S.  These companies would be guaranteed a profit based on a set rate of return on the costs of high-quality domestic manufacturing.  In order to maintain their manufacturing rights, facilities would have to meet strict FDA guidelines to ensure high quality drugs. 

Like the Warren and California proposals, this approach would tackle several problems at once.  Prices would be kept under control and facilities would face frequent inspections to ensure quality.  A guaranteed profit would eliminate generic companies’ financial risk, reducing their incentive to use cheap (and often unsafe) drug ingredients or to engage in illegal anticompetitive behavior.  It would also encourage steady production to reduce instances of drug shortages.  Unlike the Warren and California proposals, this approach would build on the existing generic infrastructure so that taxpayers don’t have to foot the bill to set up public manufacturing.  It would also continue to incentivize the development of generic alternatives by maintaining the Hatch-Waxman exclusivity period, and it would motivate the manufacture of generic drugs by companies seeking a reliable rate of return.

Several issues would need to be worked out with a regulated generic industry approach to prevent manipulation of rates of return, regulatory capture, and political appointees without the incentives or knowledge to regulate the drug makers. However, the recurring crises affecting generic drugs indicate the industry is rife with market failures.  Perhaps only a radical new approach will achieve lasting and necessary change.

A pending case in the U.S. Court of Appeals for the 3rd Circuit has raised several interesting questions about the FTC enforcement approach and patent litigation in the pharmaceutical industry.  The case, FTC v. AbbVie, involves allegations that AbbVie (and Besins) filed sham patent infringement cases against generic manufacturer Teva (and Perrigo) for the purpose of preventing or delaying entry into the testosterone gel market in which AbbVie’s AndroGel had a monopoly.  The FTC further alleges that AbbVie and Teva settled the testosterone gel litigation in AbbVie’s favor while making a large payment to Teva in an unrelated case, behavior that, considered together, amounted to an illegal reverse payment settlement. The district court dismissed the reverse payment claims, but concluded that the patent infringement cases were sham litigation. It ordered disgorgement damages of $448 million against AbbVie and Besins which was the profit they gained from maintaining the AndroGel monopoly.

The 3rd Circuit has been asked to review several elements of the district court’s decision including whether the original patent infringement cases amounted to sham litigation, whether the payment to Teva in a separate case amounted to an illegal reverse payment, and whether the FTC has the authority to seek disgorgement damages.  The decision will help to clarify outstanding issues relating to patent litigation and the FTC’s enforcement abilities, but it also has the potential to chill pro-competitive behavior in the pharmaceutical market encouraged under Hatch-Waxman. 

First, the 3rd Circuit will review whether AbbVie’s patent infringement case was sham litigation by asking whether the district court applied the right standard and how plaintiffs must prove that lawsuits are baseless.  The district court determined that the case was a sham because it was objectively baseless (AbbVie couldn’t reasonably expect to win) and subjectively baseless (AbbVie brought the cases solely to delay generic entry into the market).  AbbVie argues that the district court erred by not requiring affirmative evidence of bad faith and not requiring the FTC to present clear and convincing evidence that AbbVie and its attorneys believed the lawsuits were baseless.

While sham litigation should be penalized and deterred, especially when it produces anticompetitive effects, the 3rd Circuit’s decision, depending on how it comes out, also has the potential to deter brand drug makers from filing patent infringement cases in the first place.  This threatens to disrupt the delicate balance that Hatch-Waxman sought to establish between protecting generic entry while encouraging brand competition.

The 3rd Circuit will also determine whether AbbVie’s payment to Teva in a separate case involving cholesterol medicine was an illegal reverse payment, otherwise known as a “pay-for-delay” settlement.  The FTC asserts that the actions in the two cases—one involving testosterone gel and the other involving cholesterol medicine—should be considered together, but the district court disagreed and determined there was no illegal reverse payment.  True pay-for-delay settlements are anticompetitive and harm consumers by delaying their access to cheaper generic alternatives.  However, an overly-liberal definition of what constitutes an illegal reverse payment will deter legitimate settlements, thereby increasing expenses for all parties that choose to litigate and possibly dissuading generics from bringing patent challenges in the first place.  Moreover, FTC’s argument that two settlements occurring in separate cases around the same time is suspicious overlooks the reality that the pharmaceutical industry has become increasingly concentrated and drug companies often have more than one pending litigation matter against another company involving entirely different products and circumstances. 

Finally, the 3rd Circuit will determine whether the FTC has the authority to seek disgorgement damages on past acts like settled patent litigation.  AbbVie has argued that the agency has no right to disgorgement because it isn’t enumerated in the FTC Act and because courts can’t order injunctive relieve, including disgorgement, on completed past acts. 

The FTC has sought disgorgement damages only sparingly, but the frequency with which the agency seeks disgorgement and the amount of the damages have increased in recent years. Proponents of the FTC’s approach argue that the threat of large disgorgement damages provides a strong deterrent to anticompetitive behavior.  While true, FTC-ordered disgorgement (even if permissible) may go too far and end up chilling economic activity by exposing businesses to exorbitant liability without clear guidance on when disgorgement will be awarded. The 3rd Circuit will determine whether the FTC’s enforcement approach is authorized, a decision that has important implications for whether the agency’s enforcement can deter unfair practices without depressing economic activity.

Last week the Senate Judiciary Committee held a hearing, Intellectual Property and the Price of Prescription Drugs: Balancing Innovation and Competition, that explored whether changes to the pharmaceutical patent process could help lower drug prices.  The committee’s goal was to evaluate various legislative proposals that might facilitate the entry of cheaper generic drugs, while also recognizing that strong patent rights for branded drugs are essential to incentivize drug innovation.  As Committee Chairman Lindsey Graham explained:

One thing you don’t want to do is kill the goose who laid the golden egg, which is pharmaceutical development. But you also don’t want to have a system that extends unnecessarily beyond the ability to get your money back and make a profit, a patent system that drives up costs for the average consumer.

Several proposals that were discussed at the hearing have the potential to encourage competition in the pharmaceutical industry and help rein in drug prices. Below, I discuss these proposals, plus a few additional reforms. I also point out some of the language in the current draft proposals that goes a bit too far and threatens the ability of drug makers to remain innovative.  

1. Prevent brand drug makers from blocking generic companies’ access to drug samples. Some brand drug makers have attempted to delay generic entry by restricting generics’ access to the drug samples necessary to conduct FDA-required bioequivalence studies.  Some brand drug manufacturers have limited the ability of pharmacies or wholesalers to sell samples to generic companies or abused the REMS (Risk Evaluation Mitigation Strategy) program to refuse samples to generics under the auspices of REMS safety requirements.  The Creating and Restoring Equal Access To Equivalent Samples (CREATES) Act of 2019 would allow potential generic competitors to bring an action in federal court for both injunctive relief and damages when brand companies block access to drug samples.  It also gives the FDA discretion to approve alternative REMS safety protocols for generic competitors that have been denied samples under the brand companies’ REMS protocol.  Although the vast majority of brand drug companies do not engage in the delay tactics addressed by CREATES, the Act would prevent the handful that do from thwarting generic competition.  Increased generic competition should, in turn, reduce drug prices.

2. Restrict abuses of FDA Citizen Petitions.  The citizen petition process was created as a way for individuals and community groups to flag legitimate concerns about drugs awaiting FDA approval.  However, critics claim that the process has been misused by some brand drug makers who file petitions about specific generic drugs in the hopes of delaying their approval and market entry.  Although FDA has indicated that citizens petitions rarely delay the approval of generic drugs, there have been a few drug makers, such as Shire ViroPharma, that have clearly abused the process and put unnecessary strain on FDA resources. The Stop The Overuse of Petitions and Get Affordable Medicines to Enter Soon (STOP GAMES) Act is intended to prevent such abuses.  The Act reinforces the FDA and FTC’s ability to crack down on petitions meant to lengthen the approval process of a generic competitor, which should deter abuses of the system that can occasionally delay generic entry.  However, lawmakers should make sure that adopted legislation doesn’t limit the ability of stakeholders (including drug makers that often know more about the safety of drugs than ordinary citizens) to raise serious concerns with the FDA. 

3. Curtail Anticompetitive Pay-for-Delay Settlements.  The Hatch-Waxman Act incentivizes generic companies to challenge brand drug patents by granting the first successful generic challenger a period of marketing exclusivity. Like all litigation, many of these patent challenges result in settlements instead of trials.  The FTC and some courts have concluded that these settlements can be anticompetitive when the brand companies agree to pay the generic challenger in exchange for the generic company agreeing to forestall the launch of their lower-priced drug. Settlements that result in a cash payment are a red flag for anti-competitive behavior, so pay-for-delay settlements have evolved to involve other forms of consideration instead.  As a result, the Preserve Access to Affordable Generics and Biosimilars Act aims to make an exchange of anything of value presumptively anticompetitive if the terms include a delay in research, development, manufacturing, or marketing of a generic drug. Deterring obvious pay-for-delay settlements will prevent delays to generic entry, making cheaper drugs available as quickly as possible to patients. 

However, the Act’s rigid presumption that an exchange of anything of value is presumptively anticompetitive may also prevent legitimate settlements that ultimately benefit consumers.  Brand drug makers should be allowed to compensate generic challengers to eliminate litigation risk and escape litigation expenses, and many settlements result in the generic drug coming to market before the expiration of the brand patent and possibly earlier than if there was prolonged litigation between the generic and brand company.  A rigid presumption of anticompetitive behavior will deter these settlements, thereby increasing expenses for all parties that choose to litigate and possibly dissuading generics from bringing patent challenges in the first place.  Indeed, the U.S. Supreme Court has declined to define these settlements as per se anticompetitive, and the FTC’s most recent agreement involving such settlements exempts several forms of exchanges of value.  Any adopted legislation should follow the FTC’s lead and recognize that some exchanges of value are pro-consumer and pro-competitive.

4. Restore the balance established by Hatch-Waxman between branded drug innovators and generic drug challengers.  I have previously discussed how an unbalanced inter partes review (IPR) process for challenging patents threatens to stifle drug innovation.  Moreover, current law allows generic challengers to file duplicative claims in both federal court and through the IPR process.  And because IPR proceedings do not have a standing requirement, the process has been exploited  by entities that would never be granted standing in traditional patent litigation—hedge funds betting against a company by filing an IPR challenge in hopes of crashing the stock and profiting from the bet. The added expense to drug makers of defending both duplicative claims and claims against challengers that are exploiting the system increases litigation costs, which may be passed on to consumers in the form of higher prices. 

The Hatch-Waxman Integrity Act (HWIA) is designed to return the balance established by Hatch-Waxman between branded drug innovators and generic drug challengers. It requires generic challengers to choose between either Hatch-Waxman litigation (which saves considerable costs by allowing generics to rely on the brand company’s safety and efficacy studies for FDA approval) or an IPR proceeding (which is faster and provides certain pro-challenger provisions). The HWIA would also eliminate the ability of hedge funds and similar entities to file IPR claims while shorting the stock.  By reducing duplicative litigation and the exploitation of the IPR process, the HWIA will reduce costs and strengthen innovation incentives for drug makers.  This will ensure that patent owners achieve clarity on the validity of their patents, which will spur new drug innovation and make sure that consumers continue to have access to life-improving drugs.

5. Curb illegal product hopping and patent thickets.  Two drug maker tactics currently garnering a lot of attention are so-called “product hopping” and “patent thickets.”  At its worst, product hopping involves brand drug makers making minor changes to a drug nearing the end of its patent so that they gets a new patent on the slightly-tweaked drug, and then withdrawing the original drug from the market so that patients shift to the newly patented drug and pharmacists can’t substitute a generic version of the original drug.  Similarly, at their worst, patent thickets involve brand drug makers obtaining a web of patents on a single drug to extend the life of their exclusivity and make it too costly for other drug makers to challenge all of the patents associated with a drug.  The proposed Affordable Prescriptions for Patients Act of 2019 is meant to stop these abuses of the patent system, which would facilitate generic entry and help to lower drug prices.

However, the Act goes too far by also capturing many legitimate activities in its definitions. For example, the bill defines as anticompetitive product-hopping the selling of any improved version of a drug during a window which extends to a year after the launch of the first generic competitor.  Presently, to acquire a patent and FDA approval, the improved version of the drug must be different and innovative enough from the original drug, yet the Act would prevent the drug maker from selling such a product without satisfying a demanding three-pronged test before the FTC or a district court.  Similarly, the Act defines as anticompetitive patent thickets any new patents filed on a drug in the same general family as the original patent, and this presumption can only be rebutted by providing extensive evidence and satisfying demanding standards to the FTC or a district court.  As a result, the Act deters innovation activity that is at all related to an initial patent and, in doing so, ignores the fact that most important drug innovation is incremental innovation based on previous inventions.  Thus, the proposal should be redrafted to capture truly anticompetitive product hopping and patent thicket activity, while exempting behavior this is critical for drug innovation. 

Reforms that close loopholes in the current patent process should facilitate competition in the pharmaceutical industry and help to lower drug prices.  However, lawmakers need to be sure that they don’t restrict patent rights to the extent that they deter innovation because a significant body of research predicts that patients’ health outcomes will suffer as a result.

Longtime TOTM blogger, Paul Rubin, has a new book now available for preorder on Amazon.

The book’s description reads:

In spite of its numerous obvious failures, many presidential candidates and voters are in favor of a socialist system for the United States. Socialism is consistent with our primitive evolved preferences, but not with a modern complex economy. One reason for the desire for socialism is the misinterpretation of capitalism.   

The standard definition of free market capitalism is that it’s a system based on unbridled competition. But this oversimplification is incredibly misleading—capitalism exists because human beings have organically developed an elaborate system based on trust and collaboration that allows consumers, producers, distributors, financiers, and the rest of the players in the capitalist system to thrive.

Paul Rubin, the world’s leading expert on cooperative capitalism, explains simply and powerfully how we should think about markets, economics, and business—making this book an indispensable tool for understanding and communicating the vast benefits the free market bestows upon societies and individuals. 

On March 14, the Federal Circuit will hear oral arguments in the case of BTG International v. Amneal Pharmaceuticals that could dramatically influence the future of duplicative patent litigation in the pharmaceutical industry.  The court will determine whether the America Invents Act (AIA) bars patent challengers that succeed in invalidating patents in inter partes review (IPR) proceedings from repeating their winning arguments in district court.  Courts and litigants had previously assumed that the AIA’s estoppel provision only prevented unsuccessful challengers from reusing failed arguments.   However, in an amicus brief filed in the case last month, the U.S. Patent and Trade Office (USPTO) argued that, although it seems counterintuitive, under the AIA, even parties that succeed in getting patents invalidated in IPR cannot reuse their arguments. 

If the Federal Circuit agrees with the USPTO, patent challengers could be strongly deterred from bringing IPR proceedings because it would mean they couldn’t reuse any arguments in district court.  This deterrent effect would be especially strong for generic drug makers, who must prevail in district court in order to get approval for their Abbreviated New Drug Application from the FDA. 

Critics of the USPTO’s position assert that it will frustrate the AIA’s purpose of facilitating generic competition.  However, if the Federal Circuit adopts the position, it would also reduce the amount of duplicative litigation that plagues the pharmaceutical industry and threatens new drug innovation.  According to a 2017 analysis of over 6,500 IPR challenges filed between 2012 and 2017, approximately 80% of IPR challenges were filed during an ongoing district court case challenging the patent.   This duplicative litigation can increase costs for both challengers and patent holders; the median cost for an IPR proceeding that results in a final decision is $500,000 and the median cost for just filing an IPR petition is $100,000.  Moreover, because of duplicative litigation, pharmaceutical patent holders face persistent uncertainty about the validity of their patents. Uncertain patent rights will lead to less innovation because drug companies will not spend the billions of dollars it typically costs to bring a new drug to market when they cannot be certain if the patents for that drug can withstand IPR proceedings that are clearly stacked against them.   And if IPR causes drug innovation to decline, a significant body of research predicts that patients’ health outcomes will suffer as a result.

In addition, deterring IPR challenges would help to reestablish balance between drug patent owners and patent challengers.  As I’ve previously discussed here and here, the pro-challenger bias in IPR proceedings has led to significant deviation in patent invalidation rates under the two pathways; compared to district court challenges, patents are twice as likely to be found invalid in IPR challenges. The challenger is more likely to prevail in IPR proceedings because the Patent Trial and Appeal Board (PTAB) applies a lower standard of proof for invalidity in IPR proceedings than do federal courts. Furthermore, if the challenger prevails in the IPR proceedings, the PTAB’s decision to invalidate a patent can often “undo” a prior district court decision in favor of the patent holder.  Further, although both district court judgments and PTAB decisions are appealable to the Federal Circuit, the court applies a more deferential standard of review to PTAB decisions, increasing the likelihood that they will be upheld compared to the district court decision. 

However, the USPTO acknowledges that its position is counterintuitive because it means that a court could not consider invalidity arguments that the PTAB found persuasive.  It is unclear whether the Federal Circuit will refuse to adopt this counterintuitive position or whether Congress will amend the AIA to limit estoppel to failed invalidity claims.  As a result, a better and more permanent way to eliminate duplicative litigation would be for Congress to enact the Hatch-Waxman Integrity Act of 2019 (HWIA).  The HWIA was introduced by Senator Thom Tillis in the Senate and Congressman Bill Flores In the House, and proposed in the last Congress by Senator Orrin Hatch.  The HWIA eliminates the ability of drug patent challengers to file duplicative claims in both federal court and IPR proceedings.  Instead, they must choose between either district court litigation (which saves considerable costs by allowing generics to rely on the brand company’s safety and efficacy studies for FDA approval) and IPR proceedings (which are faster and provide certain pro-challenger provisions). 

Thus, the HWIA would reduce duplicative litigation that increases costs and uncertainty for drug patent owners.   This will ensure that patent owners achieve clarity on the validity of their patents, which will spur new drug innovation and ensure that consumers continue to have access to life-improving drugs.

Drug makers recently announced their 2019 price increases on over 250 prescription drugs. As examples, AbbVie Inc. increased the price of the world’s top-selling drug Humira by 6.2 percent, and Hikma Pharmaceuticals increased the price of blood-pressure medication Enalaprilat by more than 30 percent. Allergan reported an average increase across its portfolio of drugs of 3.5 percent; although the drug maker is keeping most of its prices the same, it raised the prices on 27 drugs by 9.5 percent and on another 24 drugs by 4.9 percent. Other large drug makers, such as Novartis and Pfizer, will announce increases later this month.

So far, the number of price increases is significantly lower than last year when drug makers increased prices on more than 400 drugs.  Moreover, on the drugs for which prices did increase, the average price increase of 6.3 percent is only about half of the average increase for drugs in 2018. Nevertheless, some commentators have expressed indignation and President Trump this week summoned advisors to the White House to discuss the increases.  However, commentators and the administration should keep in mind what the price increases actually mean and the numerous players that are responsible for increasing drug prices. 

First, it is critical to emphasize the difference between drug list prices and net prices.  The drug makers recently announced increases in the list, or “sticker” prices, for many drugs.  However, the list price is usually very different from the net price that most consumers and/or their health plans actually pay, which depends on negotiated discounts and rebates.  For example, whereas drug list prices increased by an average of 6.9 percent in 2017, net drug prices after discounts and rebates increased by only 1.9 percent. The differential between the growth in list prices and net prices has persisted for years.  In 2016 list prices increased by 9 percent but net prices increased by 3.2 percent; in 2015 list prices increased by 11.9 percent but net prices increased by 2.4 percent, and in 2014 list price increases peaked at 13.5 percent but net prices increased by only 4.3 percent.

For 2019, the list price increases for many drugs will actually translate into very small increases in the net prices that consumers actually pay.  In fact, drug maker Allergan has indicated that, despite its increase in list prices, the net prices that patients actually pay will remain about the same as last year.

One might wonder why drug makers would bother to increase list prices if there’s little to no change in net prices.  First, at least 40 percent of the American prescription drug market is subject to some form of federal price control.  As I’ve previously explained, because these federal price controls generally require percentage rebates off of average drug prices, drug makers have the incentive to set list prices higher in order to offset the mandated discounts that determine what patients pay.

Further, as I discuss in a recent Article, the rebate arrangements between drug makers and pharmacy benefit managers (PBMs) under many commercial health plans create strong incentives for drug makers to increase list prices. PBMs negotiate rebates from drug manufacturers in exchange for giving the manufacturers’ drugs preferred status on a health plan’s formulary.  However, because the rebates paid to PBMs are typically a percentage of a drug’s list price, drug makers are compelled to increase list prices in order to satisfy PBMs’ demands for higher rebates. Drug makers assert that they are pressured to increase drug list prices out of fear that, if they do not, PBMs will retaliate by dropping their drugs from the formularies. The value of rebates paid to PBMs has doubled since 2012, with drug makers now paying $150 billion annually.  These rebates have grown so large that, today, the drug makers that actually invest in drug innovation and bear the risk of drug failures receive only 39 percent of the total spending on drugs, while 42 percent of the spending goes to these pharmaceutical middlemen.

Although a portion of the increasing rebate dollars may eventually find its way to patients in the form of lower co-pays, many patients still suffer from the list prices increases.  The 29 million Americans without drug plan coverage pay more for their medications when list prices increase. Even patients with insurance typically have cost-sharing obligations that require them to pay 30 to 40 percent of list prices.  Moreover, insured patients within the deductible phase of their drug plan pay the entire higher list price until they meet their deductible.  Higher list prices jeopardize patients’ health as well as their finances; as out-of-pocket costs for drugs increase, patients are less likely to adhere to their medication routine and more likely to abandon their drug regimen altogether.

Policymakers must realize that the current system of government price controls and distortive rebates creates perverse incentives for drug makers to continue increasing drug list prices. Pointing the finger at drug companies alone for increasing prices does not represent the problem at hand.

Last week, Senator Orrin Hatch, Senator Thom Tillis, and Representative Bill Flores introduced the Hatch-Waxman Integrity Act of 2018 (HWIA) in both the Senate and the House of Representatives.  If enacted, the HWIA would help to ensure that the unbalanced inter partes review (IPR) process does not stifle innovation in the drug industry and jeopardize patients’ access to life-improving drugs.

Created under the America Invents Act of 2012, IPR is a new administrative pathway for challenging patents. It was, in large part, created to fix the problem of patent trolls in the IT industry; the trolls allegedly used questionable or “low quality” patents to extort profits from innovating companies.  IPR created an expedited pathway to challenge patents of dubious quality, thus making it easier for IT companies to invalidate low quality patents.

However, IPR is available for patents in any industry, not just the IT industry.  In the market for drugs, IPR offers an alternative to the litigation pathway that Congress created over three decades ago in the Hatch-Waxman Act. Although IPR seemingly fixed a problem that threatened innovation in the IT industry, it created a new problem that directly threatened innovation in the drug industry. I’ve previously published an article explaining why IPR jeopardizes drug innovation and consumers’ access to life-improving drugs. With Hatch-Waxman, Congress sought to achieve a delicate balance between stimulating innovation from brand drug companies, who hold patents, and facilitating market entry from generic drug companies, who challenge the patents.  However, IPR disrupts this balance as critical differences between IPR proceedings and Hatch-Waxman litigation clearly tilt the balance in the patent challengers’ favor. In fact, IPR has produced noticeably anti-patent results; patents are twice as likely to be found invalid in IPR challenges as they are in Hatch-Waxman litigation.

The Patent Trial and Appeal Board (PTAB) applies a lower standard of proof for invalidity in IPR proceedings than do federal courts in Hatch-Waxman proceedings. In federal court, patents are presumed valid and challengers must prove each patent claim invalid by “clear and convincing evidence.” In IPR proceedings, no such presumption of validity applies and challengers must only prove patent claims invalid by the “preponderance of the evidence.”

Moreover, whereas patent challengers in district court must establish sufficient Article III standing, IPR proceedings do not have a standing requirement.  This has given rise to “reverse patent trolling,” in which entities that are not litigation targets, or even participants in the same industry, threaten to file an IPR petition challenging the validity of a patent unless the patent holder agrees to specific pre-filing settlement demands.  The lack of a standing requirement has also led to the  exploitation of the IPR process by entities that would never be granted standing in traditional patent litigation—hedge funds betting against a company by filing an IPR challenge in hopes of crashing the stock and profiting from the bet.

Finally, patent owners are often forced into duplicative litigation in both IPR proceedings and federal court litigation, leading to persistent uncertainty about the validity of their patents.  Many patent challengers that are unsuccessful in invalidating a patent in district court may pursue subsequent IPR proceedings challenging the same patent, essentially giving patent challengers “two bites at the apple.”  And if the challenger prevails in the IPR proceedings (which is easier to do given the lower standard of proof), the PTAB’s decision to invalidate a patent can often “undo” a prior district court decision.  Further, although both district court judgments and PTAB decisions are appealable to the Federal Circuit, the court applies a more deferential standard of review to PTAB decisions, increasing the likelihood that they will be upheld compared to the district court decision.

The pro-challenger bias in IPR creates significant uncertainty for patent rights in the drug industry.  As an example, just last week patent claims for drugs generating $6.5 billion for drug company Sanofi were invalidated in an IPR proceeding.  Uncertain patent rights will lead to less innovation because drug companies will not spend the billions of dollars it typically costs to bring a new drug to market when they cannot be certain if the patents for that drug can withstand IPR proceedings that are clearly stacked against them.   And, if IPR causes drug innovation to decline, a significant body of research predicts that patients’ health outcomes will suffer as a result.

The HWIA, which applies only to the drug industry, is designed to return the balance established by Hatch-Waxman between branded drug innovators and generic drug challengers. It eliminates challengers’ ability to file duplicative claims in both federal court and through the IPR process. Instead, they must choose between either Hatch-Waxman litigation (which saves considerable costs by allowing generics to rely on the brand company’s safety and efficacy studies for FDA approval) and IPR (which is faster and provides certain pro-challenger provisions). In addition to eliminating generic challengers’ “second bite of the apple,” the HWIA would also eliminate the ability of hedge funds and similar entities to file IPR claims while shorting the stock.

Thus, if enacted, the HWIA would create incentives that reestablish Hatch-Waxman litigation as the standard pathway for generic challenges to brand patents.  Yet, it would preserve IPR proceedings as an option when speed of resolution is a primary concern.  Ultimately, it will restore balance to the drug industry to safeguard competition, innovation, and patients’ access to life-improving drugs.

The two-year budget plan passed last week makes important changes to payment obligations in the Medicare Part D coverage gap, also known as the donut hole.  While the new plan produces a one-year benefit for seniors by reducing what they pay a year earlier than was already mandated, it permanently shifts much of the drug costs insurance companies were paying to drug makers.  It’s far from clear whether this windfall for insurers will result in lower drug costs for Medicare beneficiaries.

Medicare Part D is voluntary prescription drug insurance for seniors and the permanently disabled provided by private insurance plans that are approved by the Medicare program.  Last year, more than 42 million people enrolled in Medicare Part D plans. Payment for prescription drugs under Medicare Part D depends on how much enrollees spend on drugs.  In 2018, after hitting a deductible that varies by plan, enrollees pay 25% of their drug costs while the Part D plans pay 75%.  However, once the individual and the plan have spent a total of $3,750, enrollees hit the coverage gap that lasts until $8,418 has been spent.  In the coverage gap, enrollees pay 35% of brand drug costs, the Part D plans pay 15%, and drug makers are required to offer 50% discounts on brand drugs to cover the rest.  Once total spending reaches $8,418, enrollees enter catastrophic coverage in which they pay only 5% of drug costs, the Part D plans pay 15%, and the Medicare program pays the other 80%.

The Affordable Care Act (ACA) included provisions to phase out the coverage gap by 2020, so that enrollees will pay only 25% of drug costs from the time they meet the deductible until they hit the catastrophic coverage level.  The budget plan passed last week speeds up this phase out by one year, so enrollees will start paying only 25% in 2019 instead of 2020.  The ACA anticipated that with enrollees paying 25% of drug costs and drug maker discounts of 50%, the Part D plans would pay the other 25%.  However, last week’s budget plan drastically redistributed the payment responsibilities from the Part D insurance plans to drug makers. Under the new plan drug makers are required to offer 70% discounts so that the plans only have to pay 5% of the total drug costs.  That is, the new plan shifts 20% of total drug costs in the coverage gap from insurers to drug makers.

Although the drug spending in each individual’s coverage gap is less than $5,000, with over 42 million people covered, the total spending, and the 20% of spending shifted from insurers to drug makers, is significant.  CMS has estimated that when drug makers’ discounts were only covering 50% of drug spending in the gap, the annual total discounts amounted to over $5.6 billion.  Requiring drug makers to cover another 20% of drug spending will add several billion dollars more to this total.

A government intervention that forces suppliers to cover 70% of the spending in a market is a surprising move for Republicans—supposed advocates of free markets.  Moreover, although reducing prescription drug costs has become a national priority, it’s unclear whether shifting costs from insurers to drug makers will benefit individuals at all.  Theoretically, as the individual Part D plans pay less of their enrollees’ drug costs, they should pass on the savings to enrollees in the form of lower premiums.  However, several studies suggest that enrollees may not experience a net decrease in drug spending.  The Centers for Medicare and Medicaid Services (CMS) has determined that under Medicare Part D, drug makers increase list prices to offset other concessions and to more quickly move enrollees out of the coverage gap where drug makers are required to offer price discounts.  Higher list prices mean that enrollees’ total out-of-pocket drug spending increases; even a 5% cost-sharing obligation in the catastrophic coverage for a high-priced drug can be a significant expense. Higher list prices that push enrollees out of the coverage gap also shift more costs onto the Medicare program that pays 80% of drug costs in the catastrophic coverage phase.

A better, more direct way to reduce Medicare Part D enrollees’ out-of-pocket drug spending is to require point-of-sale rebates.  Currently, drug makers offer rebates to Part D plans in order to improve their access to the millions of individuals covered by the plans.  However, the rebates, which total over $16 billion annually, are paid after the point-of-sale, and evidence shows that only a portion of these rebates get passed through to beneficiaries in the form of reduced insurance premiums.  Moreover, a reduction in premiums does little to benefit those enrolled individuals who have the highest aggregate out-of-pocket spending on drugs. (As an aside, in contrast to the typical insurance subsidization of high-cost enrollees by low-cost enrollees, high-spending enrollees under Medicare Part D generate greater rebates for their plans, but then the rebates are spread across all enrollees in the form of lower premiums).

Drug maker rebates will more directly benefit Medicare Part D enrollees if rebates are passed through at the point-of-sale to reduce drug copays.  Point-of-sale rebates would ensure that enrollees see immediate savings as they meet their cost-sharing obligations.  Moreover, the enrollees with the highest aggregate out-of-pocket spending would be the ones to realize the greatest savings.  CMS has recently solicited comments on a plan to require some portion of drug makers’ rebates to be applied at the point of sale, and the President’s budget plan released yesterday proposes point-of-sale rebates to lower Medicare Part D enrollees’ out-of-pocket spending.  Ultimately, targeting rebates to consumers at the point-of-sale will more effectively lower drug spending than reducing insurance plans’ payment obligations in hopes that they pass on the savings to enrollees.

Last week, several major drug makers marked the new year by announcing annual increases on list prices.  In addition to drug maker Allergan—which pledged last year to confine price increases below 10 percent and, true to its word, reported 2018 price increases of 9.5 percent—several other companies also stuck to single-digit increases.   Although list or “sticker” prices generally increased by around 9 percent for most drugs, after discounts negotiated with various health plans, the net prices that consumers and insurers actually pay will see much lower increases. For example, Allergan expects that payors will only see net price increases of 2 to 3 percent in 2018.

However, price increases won’t generate the same returns for brand drug companies that they once did.  As insurers and pharmacy benefit managers consolidate and increase their market share, they have been able to capture an increasing share of the money spent on drugs for themselves. Indeed, a 2017 report found that, of the money spent on prescription drugs by patients and health plans at the point of sale, brand drug makers only realized 39 percent.  Meanwhile, supply-chain participants, such as pharmacy benefit managers, realized 42 percent of these expenditures.  What’s more, year-after-year, brand drug makers have seen their share of these point-of-sale expenditures decrease while supply-chain entities have kept a growing share of expenditures for themselves.

Brand drug makers have also experienced a dramatic decline in the return on their R&D investment.  A recent Deloitte study reports that, for the large drug makers they’ve followed since 2010, R&D returns have dropped from over 10 percent to under 4 percent for the last two years.  The ability of supply-chain entities to capture an increasing share of drug expenditures is responsible for at least part of drug makers’ decreasing R&D returns; the study reports that average peak sales for drugs have slowly dropped over time, mirroring drug maker’s decreasing share of expenditures.  In addition, the decline in R&D returns can be traced to the increasing cost of bringing drugs to market; for the companies Deloitte studied, the cost to bring a drug to market has increased from just over $1.1 billion in 2010 to almost $2 billion in 2017.

Brand drug makers’ decreasing share of drug expenditures and declining R&D returns reduce incentives to innovate.  As the payoff from innovation declines, fewer companies will devote the substantial resources necessary to develop innovative new drugs.  In addition, innovation is threatened as brand companies increasingly face uncertainty about the patent rights of the drugs they do bring to market.  As I’ve discussed in a previous post,  the unbalanced inter partes review (IPR) process created under the Leahy-Smith America Invents Act in 2012 has led to significantly higher patent invalidation rates.  Compared to traditional district-court litigation, several pro-challenger provisions under IPR—including a lower standard of proof, a broader claim construction standard, and the ability of patent challengers to force patent owners into duplicative litigation—have resulted in twice as many patents deemed invalid in IPR proceedings.  Moreover, the lack of a standing requirement in IPR proceedings has given rise to “reverse patent trolling,” in which entities that are not litigation targets, or even participants in the same industry, threaten to file an IPR petition challenging the validity of a patent unless the patent holder agrees to specific settlement demands.  Even supporters of IPR proceedings recognize the flaws with the system; as Senator Orrin Hatch stated in a 2017 speech: “Such manipulation is contrary to the intent of IPR and the very purpose of intellectual property law. . . I think Congress needs to take a look at it.” Although the constitutionality of the IPR process is currently under review by the U.S. Supreme Court, if the unbalanced process remains unchanged, the significant uncertainty it creates for drug makers’ patent rights will lead to less innovation in the pharmaceutical industry.  Drug makers will have little incentive to spend billions of dollars to bring a new drug to market when they cannot be certain if the patents for that drug can withstand IPR proceedings that are clearly stacked against them.

We are likely to see a renewed push for drug pricing reforms in 2018 as access to affordable drugs remains a top policy priority.  Although Congress has yet to come together in support of any specific proposal, several states are experimenting with reforms that aim to lower drug prices by requiring more pricing transparency and notice of price increases.  As lawmakers consider these and other reforms, they should consider the current challenges that drug makers already face as their share of drug expenditures and R&D returns decline and patent rights remain uncertain.  Reforms that further threaten drug makers’ financial incentives to innovate could reduce our access to life-saving and life-improving new drugs.

It’s been six weeks since drug maker Allergan announced that it had assigned to the Saint Regis Mohawk Tribe the patents on Restasis, an Allergan drug challenged both in IPR proceedings and in Hatch-Waxman proceedings in federal district court.  The unorthodox agreement was intended to shield the patents from IPR proceedings (and thus restrict the challenge to district court) as the Mohawks would seek to dismiss the IPR proceedings based on the tribe’s sovereign immunity.  Although Allergan  suffered a setback last week when the federal court invalidated the Restasis patents and, in dicta, expressed concern about the Allergan/Mohawk arrangement, several other entities are following Allergan’s lead and assigning patents to sovereigns in hopes of avoiding IPR proceedings.

As an example, in August, SRC Labs assigned about 40 computer technology patents to the Saint Regis Mohawk Tribe.  Last week, the tribe, with SRC as co-plaintiff, filed lawsuits against Microsoft and Amazon for infringement of its data processing patents; the assignment of the SRC patents to the tribe could prevent a counter-challenge from Microsoft and Amazon in IPR proceedings.  Similarly, Prowire LLC, who has sued Apple for infringement, has assigned the patent in question to MEC Resources, a company affiliated with three tribes in North Dakota.  And state universities (whom the PTAB considers to be arms of the sovereign states, and thus immune to IPR challenges) are in discussions with lawyers about offering their sovereign immunity to patent owners as a way to shield patents in IPR proceedings.

These arrangements that attempt to avoid the IPR process and force patent challenges into federal courts are no surprise given the current unbalance in the IPR system.  Critical differences exist between IPR proceedings and Hatch-Waxman litigation that have created a significant deviation in patent invalidation rates under the two pathways; compared to district court challenges, patents are twice as likely to be found invalid in IPR challenges.

The PTAB applies a lower standard of proof for invalidity in IPR proceedings than do federal courts in Hatch-Waxman proceedings. In federal court, patents are presumed valid and challengers must prove each patent claim invalid by “clear and convincing evidence.” In IPR proceedings, no such presumption of validity applies and challengers must only prove patent claims invalid by the “preponderance of the evidence.” In addition to the lower burden, it is also easier for challengers to meet the standard of proof in IPR proceedings.  In federal court, patent claims are construed according to their “ordinary and customary meaning” to a person of ordinary skill in the art.  In contrast, the PTAB uses the more lenient “broadest reasonable interpretation” standard; this more lenient standard can result in the PTAB interpreting patent claims as “claiming too much” (using their broader standard), resulting in the invalidation of more patents.

Moreover, whereas patent challengers in district court must establish sufficient Article III standing, IPR proceedings do not have a standing requirement.  This has given rise to “reverse patent trolling,” in which entities that are not litigation targets, or even participants in the same industry, threaten to file an IPR petition challenging the validity of a patent unless the patent holder agrees to specific pre-filing settlement demands.  The lack of a standing requirement has also led to the  exploitation of the IPR process by entities that would never be granted standing in traditional patent litigation—hedge funds betting against a company by filing an IPR challenge in hopes of crashing the stock and profiting from the bet.

Finally, patent owners are often forced into duplicative litigation in both IPR proceedings and federal court litigation, leading to persistent uncertainty about the validity of their patents.  Many patent challengers that are unsuccessful in invalidating a patent in district court may pursue subsequent IPR proceedings challenging the same patent, essentially giving patent challengers “two bites at the apple.”  And if the challenger prevails in the IPR proceedings (which is easier to do given the lower standard of proof and broader claim construction standard), the PTAB’s decision to invalidate a patent can often “undo” a prior district court decision.  Further, although both district court judgments and PTAB decisions are appealable to the Federal Circuit, the court applies a more deferential standard of review to PTAB decisions, increasing the likelihood that they will be upheld compared to the district court decision.

Courts are increasingly recognizing that certain PTAB practices are biased against patent owners, and, in some cases, violations of underlying law.  The U.S. Supreme Court in Cuozzo Speed Technologies v. Lee concluded that the broadest reasonable interpretation claim construction standard in IPR “increases the possibility that the examiner will find the claim too broad (and deny it)” and that the different claim construction standards in PTAB trials and federal court “may produce inconsistent results and cause added confusion.”  However, the Court concluded that only Congress could mandate a different standard.  Earlier this month, in Aqua Products, Inc. v. Matal, the Federal Circuit held that “[d]espite repeated recognition of the importance of the patent owner’s right to amend [patent claims] during IPR proceedings— by Congress, courts, and the PTO alike—patent owners largely have been prevented from amending claims in the context of IPRs.”   And the Supreme Court has agreed to hear Oil States Energy Services v. Greene’s Energy Group, which questions whether IPR proceedings are even constitutional because they extinguish private property rights through a non-Article III forum without a jury. 

As Courts and lawmakers continue to question the legality and wisdom of IPR to review pharmaceutical patents, they should remember that the relationship between drug companies and patients resembles a social contract. Under this social contract, patients have the right to reasonably-priced, innovative drugs and sufficient access to alternative drug choices, while drug companies have the right to earn profits that compensate for the risk inherent in developing new products and to a stable environment that gives the companies the incentive and ability to innovate.  This social contract requires a balancing of prices (not too high to gouge consumers but not too low to insufficiently compensate drug companies), competition law (not so lenient that it ignores anticompetitive behavior that restricts patients’ access to alternative drugs, but not so strict that it prevents companies from intensely competing for profits), and most importantly in the context of IPR, patent law (not so weak that it fails to incentivize innovation and drug development, but not so strong that it enables drug companies to monopolize the market for an unreasonable amount of time).  The unbalanced IPR process threatens this balance by creating significant uncertainty in pharmaceutical intellectual property rights.  Uncertain patent rights will lead to less innovation in the pharmaceutical industry because drug companies will not spend the billions of dollars it typically costs to bring a new drug to market when they cannot be certain if the patents for that drug can withstand IPR proceedings that are clearly stacked against them.  Indeed, last week former Federal Circuit Chief Judge Paul Redmond Michel acknowledged that IPR has contributed to “hobbling” our nation’s patent system, “discourag[ing] investment, R&D and commercialization.” And if IPR causes drug innovation to decline, a significant body of research predicts that consumers’ health outcomes will suffer as a result.

Last Friday, drug maker Allergan and the Saint Regis Mohawk Tribe announced that they had reached an agreement under which Allergan assigned the patents on its top-selling drug Restasis to the tribe and, in return, Allergan was given the exclusive license on the Restasis patents so that it can continue producing and distributing the drug.  Allergan agreed to pay $13.75 million to the tribe for the deal, and up to $15 million annually in royalties as long as the patents remain valid.

Why would a large drug maker assign the patents on a leading drug to a sovereign Indian nation?  This unorthodox agreement may actually be a brilliant strategy that enables patent owners to avoid the unbalanced inter partes review (IPR) process.  The validity of the Restasis patents is currently being challenged both in IPR proceedings before the Patent Trial and Appeal Board (PTAB) and in federal district court in Texas.  However, the Allergan-Mohawk deal may lead to the dismissal of the IPR proceedings as, under the terms of the deal, the Mohawks will file a motion to dismiss the IPR proceedings based on the tribe’s sovereign immunity.  Earlier this year, in Covidien v. University of Florida Research Foundation, the PTAB determined that sovereign immunity shields state universities holding patents from IPR proceedings, and the same reasoning should certainly apply to sovereign Indian nations.

I’ve published a previous article explaining why pharmaceutical companies have legitimate reasons to avoid IPR proceedings–critical differences between district court litigation and IPR proceedings jeopardize the delicate balance Hatch-Waxman sought to achieve between patent owners and patent challengers. In addition to forcing patent owners into duplicative litigation in district courts and the PTAB, depriving them of the ability to achieve finality in one proceeding, the PTAB also applies a lower standard of proof for invalidity than do district courts in Hatch-Waxman litigation.  It is also easier to meet the standard of proof in a PTAB trial because of a more lenient claim construction standard.  Moreover, on appeal, PTAB decisions in IPR proceedings are given more deference than lower district court decisions.  Finally, while patent challengers in district court must establish sufficient Article III standing, IPR proceedings do not have a standing requirement.  This has led to the exploitation of the IPR process by entities that would never be granted standing in traditional patent litigation—hedge funds betting against a company by filing an IPR challenge in hopes of crashing the stock and profiting from the bet.

The differences between district court litigation and IPR proceedings have created a significant deviation in patent invalidation rates under the two pathways; compared to district court challenges, patents are twice as likely to be found invalid in IPR challenges.  Although the U.S. Supreme Court in Cuozzo Speed Technologies v. Lee concluded that the anti-patentee claim construction standard in IPR “increases the possibility that the examiner will find the claim too broad (and deny it)”, the Court concluded that only Congress could mandate a different standard.  So far, Congress has done nothing to reduce the disparities between IPR proceedings and Hatch-Waxman litigation. But, while we wait, the high patent invalidation rate in IPR proceedings creates significant uncertainty for patent owners’ intellectual property rights.   Uncertain patent rights, in turn, lead to less innovation in the pharmaceutical industry.  Put simply, drug companies will not spend the billions of dollars it typically costs to bring a new drug to market when they can’t be certain if the patents for that drug can withstand IPR proceedings that are clearly stacked against them (for an excellent discussion of how the PTAB threatens innovation, see Alden Abbot’s recent TOTM post).  Thus, deals between brand companies and sovereigns, such as Indian nations, that insulate patents from IPR proceedings should improve the certainty around intellectual property rights and protect drug innovation.

Yet, the response to the Allergan-Mohawk deal among some scholars and generic drug companies has been one of panic and speculative doom.  Critics have questioned the deal largely on the grounds that, in addition to insulating Restasis from IPR proceedings, tribal sovereignty might also shield the patents in standard Hatch-Waxman district court litigation.  If this were true and brand companies began to routinely house their patents with sovereign Indian nations, then the venues in which generic companies could challenge patents would be restricted and generic companies would have less incentive to produce and market cheaper drugs.

However, it is far from clear that these deals could shield patents in standard Hatch-Waxman district court litigation.  Hatch-Waxman litigation typically follows a familiar pattern: a generic company files a Paragraph IV ANDA alleging patent owner’s patents are invalid or will not be infringed, the patent owner then sues the generic for infringement, and then the generic company files a counterclaim for invalidity.  Critics of the Allergan-Mohawk deal allege that tribal sovereignty could insulate patent owners from the counterclaim.  However, courts have held that state universities waive sovereign immunity for counterclaims when they file the initial patent infringement suit.  Although, in non-infringement contexts, tribes have been found to not waive sovereign immunity for counterclaims merely by filing an action as a plaintiff, this has never been tested in patent litigation.  Moreover, even if sovereign immunity could be used to prevent the counterclaim, invalidity can still be raised as an affirmative defense in the patent owner’s infringement suit (although it has been asserted that requiring generics to assert invalidity as an affirmative defense instead of a counterclaim may still tilt the playing field toward patent owners).  Finally, many patent owners that are sovereigns may choose to voluntarily waive sovereign immunity to head off any criticism or congressional meddling. Given the uncertainty of the effects of tribal sovereignty in Hatch-Waxman litigation, Allergan has concluded that their deal with the Mohawks won’t affect the pending district court litigation involving the validity of the Restasis patents.  However, if tribes in future cases were to cloud the viability of Hatch-Waxman by asserting sovereign immunity in district court litigation, Congress could always respond by altering the Hatch-Waxman rules to preclude this.

For now, we should all take a deep breath and put the fearmongering on hold.  Whether deals like the Allergan-Mohawk arrangement could affect Hatch-Waxman litigation is simply a matter of speculation, and there are many reasons to believe that they won’t. In the meantime, the deal between Allergan and the Saint Regis Mohawk Tribe is an ingenious strategy to avoid the unbalanced IPR process.   This move is the natural extension of the PTAB’s ruling on state university sovereign immunity, and state universities are likely incorporating the advantage into their own licensing and litigation strategies.  The Supreme Court will soon hear a case questioning the constitutionality of the IPR process.  Until the courts or Congress act to reduce the disparities between IPR proceedings and Hatch-Waxman litigation, we can hardly blame patent owners from taking clever legal steps to avoid the unbalanced IPR process.

Today, the Senate Committee on Health, Education, Labor, and Pensions (HELP) enters the drug pricing debate with a hearing on “The Cost of Prescription Drugs: How the Drug Delivery System Affects What Patients Pay.”  By questioning the role of the drug delivery system in pricing, the hearing goes beyond the more narrow focus of recent hearings that have explored how drug companies set prices.  Instead, today’s hearing will explore how pharmacy benefit managers, insurers, providers, and others influence the amounts that patients pay.

In 2016, net U.S. drug spending increased by 4.8% to $323 billion (after adjusting for rebates and off-invoice discounts).  This rate of growth slowed to less than half the rates of 2014 and 2015, when net drug spending grew at rates of 10% and 8.9% respectively.  Yet despite the slowing in drug spending, the public outcry over the cost of prescription drugs continues.

In today’s hearing, there will be testimony both on the various causes of drug spending increases and on various proposals that could reduce the cost of drugs.  Several of the proposals will focus on ways to increase competition in the pharmaceutical industry, and in turn, reduce drug prices.  I have previously explained several ways that the government could reduce prices through enhanced competition, including reducing the backlog of generic drugs awaiting FDA approval and expediting the approval and acceptance of biosimilars.  Other proposals today will likely call for regulatory reforms to enable innovative contractual arrangements that allow for outcome- or indication-based pricing and other novel reimbursement designs.

However, some proposals will undoubtedly return to the familiar call for more government negotiation of drug prices, especially drugs covered under Medicare Part D.  As I’ve discussed in a previous post, in order for government negotiation to significantly lower drug prices, the government must be able to put pressure on drug makers to secure price concessions. This could be achieved if the government could set prices administratively, penalize manufacturers that don’t offer price reductions, or establish a formulary.  Setting prices or penalizing drug makers that don’t reduce prices would produce the same disastrous effects as price controls: drug shortages in certain markets, increased prices for non-Medicare patients, and reduced incentives for innovation. A government formulary for Medicare Part D coverage would provide leverage to obtain discounts from manufacturers, but it would mean that many patients could no longer access some of their optimal drugs.

As lawmakers seriously consider changes that would produce these negative consequences, industry would do well to voluntarily constrain prices.  Indeed, in the last year, many drug makers have pledged to limit price increases to keep drug spending under control.  Allergan was first, with its “social contract” introduced last September that promised to keep price increases below 10 percent. Since then, Novo Nordisk, AbbVie, and Takeda, have also voluntarily committed to single-digit price increases.

So far, the evidence shows the drug makers are sticking to their promises. Allergan has raised the price of U.S. branded products by an average of 6.7% in 2017, and no drug’s list price has increased by more than single digits.  In contrast, Pfizer, who has made no pricing commitment, has raised the price of many of its drugs by 20%.

If more drug makers brought about meaningful change by committing to voluntary pricing restraints, the industry could prevent the market-distorting consequences of government intervention while helping patients afford the drugs they need.   Moreover, avoiding intrusive government mandates and price controls would preserve drug innovation that has brought life-saving and life-enhancing drugs to millions of Americans.
