Gummarus, LLC has filed a second Eastern District of Texas case against Samsung (4:20-cv-00310), alleging infringement of the same six patents at issue in last April’s suit, as well as of a seventh.

Earlier this month, RPX reported the formation of several entities with apparent ties to Oso IP, LLC, two of which recently filed their first lawsuits. Now, March has seen a third such entity launch litigation, hitting Samsung (6:20-cv-00180) in the Western District of Texas. American Inventor Tech, LLC asserts two patents, generally related to managing media streams through a graphical user interface, with Robert Paul Morris named as their sole inventor. The defendant is accused of infringement through the provision of smartphones that use the Android Pie 9.0 operating system and above. American Inventor Tech is one of five Texas entities to be formed under similar circumstances roughly one month ago, and the third of those to initiate litigation of Morris patents in March.
