Detailed Summary

In an authorized response to a Director review request, Advanced Integrated Circuit Process LLC (AICP) urges the Patent Trial and Appeal Board to deny Taiwan Semiconductor Manufacturing Company Ltd.'s (TSMC) petition to compel an inter partes review of U.S. Patent 7,579,227. AICP contends that the Director properly exercised discretion to deny the request, emphasizing TSMC's failure to provide persuasive justification, the frivolous nature of its new‑facts and national‑security arguments, and the risk of duplication, expense, and inconsistent outcomes if the review proceeded. The brief also rebuts TSMC's assertions regarding settled expectations, examiner error, and candor, asserting that these theories lack substantial evidence and are contrary to established precedent. By underscoring the high legal burden on petitioners and the Board’s holistic analysis, AICP seeks a definitive denial of the Director review request.
