It has been asserted against Askey Computer Corporation and its routers, which are Wi-Fi 6 (802.11ax) enabled devices.

The '396 patent is generally directed wireless terminals that receive an A-MPDU (aggregated MAC protocol data unit) with a particular delimiter field that directs the device on the specific format of the response frame to transmit back. Like the '233, the '396 patent has been asserted against Askey and its routers, which are Wi-Fi 6 (802.11ax) enabled devices. The '396 patent is also related to U.S. Patent 11,664,926, which has been asserted against Samsung, HP Inc., and Askey.
