Detailed Summary

In an exhibit filing, Wilus Institute of Standards and Technology requested the PTAB Director’s permission to address the implications of recent director‑review decisions in Revvo and Tesla, and to submit additional evidence concerning Samsung’s claim‑construction positions in pending district‑court litigation. Wilus argued that allowing Samsung to postpone director review until after the Markman hearing would enable contradictory legal theories across forums and would breach the three‑month institution deadline set by 35 U.S.C. § 314(b). The Director denied the request, emphasizing the Board’s policy for consistent claim constructions and statutory timing requirements.
