Detailed Summary

In a Request for Director Review, Maxell, Ltd. contends that the Patent Trial and Appeal Board abused its discretion in instituting Samsung Electronics’ IPR against U.S. Patent No. 11,017,815. The Patent Owner argues that the Board erred by finding the WinTV reference publicly accessible without sufficient evidence, improperly shifting the burden of proving non‑analogous art onto Maxell, and ignoring policy concerns about filing multiple petitions against the same patent. Citing statutory provisions under 35 U.S.C. §§102(b) and 312(a)(3) and case law, Maxell urges the Director to deny institution on grounds of factual error, legal misinterpretation, and fairness.
