Two weeks after Philadelphia personal injury firm Lundy Law dropped its federal trademark suit against Philadelphia-based injury firm Larry Pitt & Associates, Pitt’s firm has sued Lundy Law and its principal, L. Leonard Lundy, in federal court alleging unfair competition and violations of the Sherman Antitrust Act.

The complaint, filed May 2 in the U.S. District Court for the Eastern District of Pennsylvania, alleges Lundy Law has entered into contracts that give the firm exclusive rights to advertise on the exteriors of Southeastern Pennsylvania Transportation Authority and Berks Area Regional Transportation Authority buses.
