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. All of the patents generally relate to a search system that operates within an instant messaging application; a new accused product is identified in this second suit: the Samsung Rich Communication Services (RCS) messaging system, with allegations targeting networking applications (e.g., Messaging as a Platform (MaaP) and/or chatbot, etc.) that can be configured on the messaging app. Gummarus recently changed counsel in its first suit, requesting and receiving a 30-day stay to make the switch—a stay that the court was told “may be useful to allow the [p]arties to work through issues in the infringement contentions” in that first case.
