PAL filed a federal antitrust class-action lawsuit against Bristol-Myers Squibb Co., alleging that the company had filed false secondary patents to prevent other drug manufacturers from bringing a generic version of its drug BuSpar to the market and also filed suit in state courts, with the support of five statewide consumer organizations. In May 2002, the 35-million-member AARP joined PAL in three lawsuits, including the BuSpar case.
