Uniloc Files Four More Cases Against Amazon, Asserting Two Patents New to Litigation and Two at Issue in an Existing Campaign
Uniloc 2017 LLC (identified as the asserted patents’ owner) and Uniloc USA, Inc. (identified as their exclusive licensee) have collectively filed four new lawsuits against Amazon (2:18-cv-00286, 2:18-cv-00287, 2:18-cv-00289, 2:18-cv-00290) in the Eastern District of Texas. Two of those cases appear to have launched new campaigns, separately asserting for the first time in litigation one patent generally related to digital video compression, and another generally related to providing variable bit rate in a streaming service. The other two cases add Amazon to an existing Uniloc campaign, begun in June 2016 by plaintiffs Uniloc Luxembourg S.A. (as patent owner) and Uniloc USA (as exclusive licensee), which have together sued more than 30 defendants over a family of patents broadly concerning group voice messaging, in complaints previously filed through June 2017. These other new complaints also identify Uniloc 2017 as the patents’ owner and Uniloc USA as their exclusive licensee.
