Sharpe Innovations, Inc. has filed the first case of 2021 in its SIM card campaign, suing Verizon (6:21-cv-00049) in the Western District of Texas, roughly six months after it dismissed without prejudice an early 2020 case against Verizon subsidiary Visible Service. Only one of the two patents asserted in that earlier case is at issue in this new one, both of them generally related to a SIM card adapter that allows use of a smaller-format SIM card in a device that uses a larger-format SIM card (where the adapter body has a cut-out region “defined by walls” and that has a floor, with that region shaped to fit a micro SIM).
