SIPCO LLC has added an April case against HP Enterprise (Aruba Networks) (1:20-cv-00537) to the two suits that it filed in March 2020, one against each of D-Link (8:20-cv-00595) and TP-Link (8:20-cv-00543). Aruba Networks is accused of infringing multiple patents through the provision of various networking products (e.g., access points, gateways, and mesh networking solutions) that use the Bluetooth 5 or Zigbee standards; D-Link and TP-Link, of infringing overlapping sets of patents through the provision of smart home routers, controllers, and sensors that use the Z-Wave or ZigBee mesh networking standards. This campaign has been running continuously since 2005, albeit with a change of ownership in the beginning of 2018.
