Headwater Research LLC has brought the number of patents asserted against Samsung to nine. Three were asserted in an October 2022 original complaint, which was amended on November 30 to add two more. A second complaint (2:22-cv-00467), also filed in the Eastern District of Texas, has brought four more patents into the litigation between the parties. All name Greg Raleigh as an inventor, belonging to an open family with over 200 issued US patents (and counterparts in multiple foreign countries). Both cases against Samsung have been assigned to District Judge Rodney Gilstrap.
