US Magistrate Judge Paul Grewal has shut down a non-practicing entity, or “patent troll,” seeking to relaunch suits against cellphone manufacturers Sony, Amazon, and Apple, among others, over 4G patents, reports MacNN (http://tinyurl.com/qhyh3e3).
Patent aggregation company Acacia and subsidiary Adaptix has been denied further suits over new products launched by the companies using the same technology. The judge says it must be satisfied with existing lawsuit results and patent agreements in place.
Adaptix sued Apple in 2013 for patent infringement. The company claimed the iPhone 5 and iPad mini infringed upon their 4G technology. (By the way, a “patent troll” is a company that licenses patents to win court rulings limiting product sales.)
