Around nine years after filing suit against Amazon, MasterObjects, Inc. has hit the tech giant (1:20-cv-03478) again, this time in the Southern District of New York (rather than the Northern District of California) and with later-issuing patents in the same family. The patents generally pertain to the use of asynchronous client-server communications to facilitate search, with infringement allegations targeting Amazon over the provision of its predictive search engine on various platforms, including the Amazon desktop website, mobile apps, and mobile websites. Last week also saw Facebook answer a MasterObjects complaint against it in the only other active case in this campaign.
MasterObjects, Inc. has filed a new lawsuit in the litigation campaign over four patents from a family generally related to the use of asynchronous client-server communications to facilitate search. The latest—and only active—defendant is Facebook (6:20-cv-00087), sued in the Western District of Texas over the provision of its predictive search engine, Typeahead (frontend system) and Unicorn (backend system). The last suit in the campaign, against eBay, ended in December 2018 after a MasterObjects win before the Patent Trial and Appeal Board (PTAB) triggered an end to a stay imposed in the district court litigation.
