In a new Southern District of California complaint, inventor-controlled Smith Interface Technologies, LLC accuses Apple (3:23-cv-01187) of infringing nine patents: five of them already in suit against Samsung and four of them new to litigation. The patents broadly concern touchscreens responsive to sequential gestures, with infringement allegations in the new complaint targeting the provision of “smartphones, portable media players, tablets, and smartwatches that run Apple iOS, iPadOS, and watchOS”, including certain models of “iPhone, iPhone SE, iPhone Pro, iPad, iPad Pro, iPad Air, iPad mini, iPod Touch, Apple Watch, and Apple Watch SE” for their inclusion of certain touchscreen gesture functionality.
