Short Summary
The Petitioner successfully demonstrated that the claims are unpatentable over prior art references Choulis, Sugiura, and Thompson. The Board adopted a broad construction of 'matrix material' and found multiple grounds for anticipation (102) and obviousness (103).
Detailed Summary
In this Final Written Decision, the Petitioner successfully demonstrated by a preponderance of the evidence that claims 1 through 16 are unpatentable over various prior art references. The Board adopted a broad interpretation of 'matrix material,' rejecting the Patent Owner's attempt to narrow the claim scope. Central to the decision was the finding that Choulis anticipates several claims, while Sugiura and Thompson anticipate or render others obvious. For obviousness, the Board found an ordinary skilled artisan would have recognized suitable substitutions (e.g., PMMA for PVK) and suggested combinations (Choulis/Yong).
