Short Summary
Wilus Institute requests Director review of the PTAB’s decision to institute an IPR against Samsung’s Wi‑Fi BSS‑color patent, arguing the Board misinterpreted prosecution statements and ignored key arguments about the Lee and Choudhury references.
Detailed Summary
In IPR2025‑00936, Samsung Electronics challenged Wilus Institute’s U.S. Patent No. 11,700,597 covering BSS‑color signaling in wireless LANs. The PTAB instituted the IPR, finding the Lee reference rendered the independent claims obvious. Wilus has filed a petition for Director review, contending that the Board erroneously equated the Lee disclosure with the claim limitation “not to use BSS color,” ignored prosecution statements distinguishing color‑based operations, and failed to consider the patent owner’s argument that Choudhury’s 1‑bit signal does not disclose the prohibited operation. The petition seeks reversal of the institution decision.
