Hanno Kaiser at the Antitrust Review reports (courtesy of the ABA listserv) that SCOTUS has granted cert in Weyerhauser (predatory buying) and Twombly (pleading standards), but not Schering-Plough (reverse payments).
Speaking of Weyerhauser, the FTC/ DOJ single firm conduct hearings started off with an examination of predatory pricing issues. The materials from the hearings are here and include presentations and submissions on both predatory selling and buying that are worth checking out.
