“Our public transit systems have been improving the customer experience by providing real-time schedule and travel information to riders,” APTA Chief Counsel James LaRusch said in a statement. “These systems, which are operating under severe financial constraints, are being saddled with these outrageous harassment claims that are a waste of time and money. This must be stopped.”

APTA said patent claims had been filed against 11 public U.S. transit agencies prior to its lawsuit.

The association said “the increase in patent infringement claims against public transit systems parallels claims on software and electronic processes in other industries.”
