Dispute Summary
TSMC seeks PTAB reversal of a Director’s discretionary denial of an IPR against its 28nm‑3nm process patents, arguing national‑security stakes, settled expectations, and material examiner errors. The petition cites extensive prior art to show lack of patentability under §§102 and 103.
