Update: Group challenges alleged patent-trolling that targets transit systems

In April, SSTI reported that a firm called ArrivalStar was asserting patent rights to a bus-arrival announcement system it claims to have invented, demanding that transit agencies and delivery companies pay for the right to use bus- and train-arrival apps and other tracking systems. Relief may be on the way. This month the San Francisco-based Electronic Freedom Foundation (EFF) challenged ArrivalStar’s patent in a request to the U.S. Patent and Trademark Office.
