Samsung Electronics has secured the institution of inter partes review proceedings at the Patent Trial and Appeal Board against 10 U.S. patents held by South Korean research lab Wilus Institute Of Standards & Technology, with decisions on two additional patents still pending.
On Jan. 5, 2026, the PTAB instituted IPR on Wilus' U.S. Patent No. 10,687,281, titled "Wireless communication method and wireless communication terminal, which use discontinuous channel." The decision brought the total number of Wilus patents facing instituted IPRs at Samsung's request to 10.
Wilus Institute Of Standards & Technology sued Samsung in three patent infringement actions filed in the U.S. District Court for the Eastern District of Texas between September 2024 and January 2025. Wilus asserted four patents in each case, for a total of 12 patents. The PTAB has now instituted review on 10 of those patents, while institution decisions on the remaining two have not yet been issued.
Wilus has also filed infringement suits in the Eastern District of Texas against Hewlett-Packard Co., Askey Computer Corp. and Askey International Corp. Samsung is the only defendant that has petitioned the PTAB to invalidate Wilus' patents.
The asserted patents, developed in South Korea by Korean inventors, relate to technologies designed to improve wireless access control and transmission efficiency in multi-user Wi-Fi environments, including channel usage and coordination methods.
