Front Row Technologies LLC has sued Cisco (6:23-cv-00035) and u-blox (3:23-cv-00157), asserting a single patent generally related to access permissions in a “venue positioning system” based on the location of a “wireless hand held device”. Cisco is accused of infringement through the provision of its Hyperlocation Modulation; u-blox, through the provision of Bluetooth indoor positioning. The patent belongs to a large family that has seen its members litigated by three plaintiffs associated with Ortiz & Lopez, PLLC (d/b/a OL PATENTS) since 2008. Front Row filed the earliest cases in this campaign, but after a set of Alice invalidations, litigation continued through two other, associated plaintiffs.
