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.
