Short Summary
The PTAB found all challenged claims unpatentable as obvious (103), primarily based on the combination of Rogers and Rosenberg. The Board rejected the Patent Owner's attempt to narrow claim language regarding 'registering modes,' holding that they are input modes within a single operating mode.
Detailed Summary
In this final decision, the PTAB determined that all 12 challenged claims were obvious under 35 U.S.C. § 103. The Board conducted extensive claim construction, ultimately finding that terms like 'first registering mode' and 'second registering mode' are not distinct operational states but rather input modes provided within a single 'registering mode.' This intrinsic evidence supported the Petitioner's argument that independent Claim 1 is obvious over Rogers and Rosenberg. Furthermore, the Board found sufficient motivation to combine various prior art references (Rogers, Rosenberg, Miyazawa, Rekimoto) for all challenged claims, confirming the unpatentability of the patent in question.
