Short Summary
The PTAB found all twenty challenged claims unpatentable in this IPR proceeding concerning backside metal adhesion. The Board adopted the Patent Owner's position that the claim language does not require strict direct contact for 'on a bottom surface.'
Detailed Summary
In this final written decision, the PTAB determined that all 20 challenged claims were unpatentable by a preponderance of the evidence. The Petitioner asserted grounds of anticipation (102) and obviousness (103), relying on multiple prior art references including Conn, Gambino, Torii, and Ide. Crucially, the Board clarified claim construction regarding 'on a bottom surface,' finding that while an embodiment shows direct contact, the open-ended language does not mandate strict physical contact. The Board ultimately found sufficient motivation and reasonable expectation of success in various combinations of prior art references to teach or render obvious the claimed invention.
