In New Campaign, Rothschild Asserts Patent on Which He Is Not a Named Inventor

April 6, 2017

The first of two Texas entities created in 2017 by Leigh M. Rothschild has now filed suit. Product Association Technologies, LLC has accused Clique Media Group (2:17-cv-00265), eBay (2:17-cv-00266), IAC/InterActive (IAC Search & Media) (2:17-cv-00269), Lyst (2:17-cv-00267), Polyvore (2:17-cv-00268), ShopStyle (2:17-cv-00270), Shopzilla (2:17-cv-00271), and Yahoo (2:17-cv-00272) of infringing a single patent (6,154,738) generally related to the use of codes to identify products on the Internet. The accused products include e-commerce websites and associated apps that use product codes. This Rothschild campaign appears to be the first to assert a patent on which Rothschild himself is not a named inventor.
