In 2015, Plaintiffs filed a First Amended Class Action Complaint on behalf of a proposed class of direct purchasers of branded and generic Namenda, a drug used to treat moderate-to-severe Alzheimer’s, alleging a two-pronged scheme on the part of Defendants to impair generic competition, including a “reverse payment” agreement to delay generic entry, and the announcement and implementation of a “product hop” or “hard switch” of the market from branded Namenda IR product to Namenda XR in order to undermine and impair generic competition when it belatedly began.  On October 28, 2019, Allergan PLC announced that it had reached a settlement agreement with direct purchaser Plaintiffs for $750 million, thus precluding a trial that was set to begin the same day in New York.

In 2017, Plaintiffs filed an Amended Complaint on behalf of a proposed class of indirect purchasers of Lovenox, and/or its generic equivalent enoxaparin, alleging an agreement among Defendants to monopolize sales of enoxaparin and prevent competition by controlling patented technology used to establish sameness for purposes of obtaining FDA approval to market generic enoxaparin.  Counsel for the Plaintiffs retained Dr. Russell Lamb to analyze whether it was possible to establish, using evidence common to the proposed class as a whole: the relevant antitrust product and geographic markets, and whether Defendants possessed market or monopoly power in those markets; the impact on prices paid by members of the proposed class that Plaintiffs allege arose from Defendants’ allegedly anticompetitive conduct; that all or nearly all members of the proposed class were injured by Defendants’ allegedly anticompetitive conduct; and that aggregate damages to the proposed class as a whole could be reliably calculated using standard economic methods and analyses.

In 2016, the Department of Labor (DOL) challenged a 2010 acquisition of the remaining 52% of shares of Sentry Equipment Erectors Inc. by its Employee Stock Ownership Plan (ESOP), claiming it overpaid in its $21 million purchase of the shares from company owner Adam Vinoskey, who was also an ESOP Trustee.
