Gravel Rating Systems LLC has filed two more cases, suing Broadcom (4:21-cv-00329) and Dish Wireless d/b/a Boost Mobile (4:21-cv-00328), both in the Eastern District of Texas, over their e-commerce websites. The plaintiff pleads that the asserted patent “resulted from the pioneering efforts of” its named inventors “in the area of a network-based knowledge sharing system and interface that allows every member of a knowledge sharing group to benefit from aggregate knowledge, experience and opinions of other members of the group”.
