VideoShare, LLC has filed another lawsuit against Alphabet (Google, YouTube) (6:19-cv-00663), accusing the defendants of infringing a single patent generally related to streaming video over a “structured hierarchical network”, with infringement allegations again focused on the YouTube video platform. This new lawsuit comes roughly two years after the Federal Circuit affirmed District Judge Gregory M. Sleet’s invalidation under Alice of two patents previously asserted by VideoShare, perhaps motivating the plaintiff to also seek a declaratory judgment from the Western District of Texas that the patent that it has asserted, which issued just this past July, is valid.
