Gravel Rating Systems LLC

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”.

Last week, Gravel Rating Systems LLC added two new suits—one each against Kohl’s (4:21-cv-00258) and McAfee (4:21-cv-00259)—to its new campaign targeting e-commerce websites. Two wireless carriers and three other retailers were hit in February with allegations of infringing the same patent, which is generally related to an information database that is connected to and receives submissions from remote computer systems. The case against one of those initial defendants has already been dismissed, without prejudice.

Gravel Rating Systems LLC has kicked off litigation over a “knowledge filter” patent, suing Cellco Partnership d/b/a Verizon Wireless (4:21-cv-00153), Costco (4:21-cv-00149), Deutsche Telekom (T-Mobile) (4:21-cv-00152), Lowe’s (4:21-cv-00150), and Target (4:21-cv-00151), all in the Eastern District of Texas. The defendants are accused of infringement through their respective provision of e-commerce websites, the complaints highlighting features for posting user reviews of products listed for sale. Gravel Rating is part of a raft of related NPEs to launch litigation over the past couple of years—one which, according to public records, continues to grow.
