Public-Transit Notifications Threatened by Patent Claim

Does the patent-holder claim credit for the train-coming heads-up? Or for the fact that it's often wrong?

The Electronic Frontier Foundation (EFF) is challenging a dangerous patent used to wrongfully demand payment from cities and other municipalities that employ public tracking systems to tell transit passengers if their bus or train is on time.

Today, EFF with the help of the Samuelson Law, Technology, and Public Policy Clinic at Berkeley Law, filed a request with the United States Patent and Trademark Office (USPTO), urging reexamination of the legitimacy of the ArrivalStar patent – used as a basis for dozens of recent lawsuits against entities like the state of California, the city of Cleveland, and the Illinois Commuter Rail.
