PTAB REJECTS GLOBALFOUNDRIES' CHALLENGE TO KATANA FINFET PATENT

The United States Patent Trial and Appeal Board has denied the institution of Inter Partes Review (IPR) IPR2022-00763 on October 7, 2022. Globalfoundries (GF), a multinational semiconductor contract manufacturing and design company, has filed the IPR seeking to invalidate US Patent 6,291,861 B1. The patent relates to state-of-the-art design and manufacturing of semiconductor devices such as FinFet Transistors.


On February 24, 2022, Katana Silicon Technologies LLC (KST) has filed a patent infringement complaint in the US District Court for the Western District of Texas against Globalfoundries. The case number is 6:22-cv-00191. The patents at issue relate to state-of-the-art semiconductor manufacturing and chip packaging technologies such as the fabrication of fin field-effect transistors (FinFETs) and Through Silicon Vias (TSVs). Previously, KST acquired a portfolio of patents from a plurality of world-leading semiconductor companies.
