Detailed Summary

In this final decision, the PTAB ruled that claims 1 through 7 and claim 18 of patent 10658378 were obvious over the prior art reference Toyama. The Board engaged in detailed claim construction, ultimately adopting a plain meaning interpretation for terms like 'isolation region of the substrate' and defining 'local contacts' as those on channel structures. Despite arguments from the Patent Owner to narrow these scopes based on specific embodiments, the Petitioner successfully demonstrated that Toyama taught the claimed limitations through unitary or combined structural interpretations, leading to the rejection of all challenged claims under § 103.
