Short Summary
The Board found that claims 1, 2, and 9 were unpatentable over prior art references Tseng and Mizuno based on obviousness. The remaining claims (3-8 and 10-24) were deemed patentable.
Detailed Summary
In this final decision, the PTAB ruled against certain claims of the patent owner, finding that Claims 1, 2, and 9 were unpatentable over prior art references Tseng and Mizuno under 35 U.S.C. § 103. The Board determined that a Person Having Ordinary Skill in the Art (POSITA) would have been motivated to combine these references to arrive at the claimed features. Conversely, the majority of the patent claims were upheld as valid.
