Short Summary
AT&T Services Inc. failed to convince the PTAB that its claims were unpatentable over prior art references Centonza and Han. The Board denied institution, finding no reasonable likelihood of prevailing on either anticipation or obviousness grounds. This decision maintains the validity of Innovative Sonic Limited's patent in cellular network connectivity.
Detailed Summary
AT&T Services Inc. petitioned to invalidate claims 1-11 of U.S. Patent No. 9736883, owned by Innovative Sonic Limited, based on prior art references Centonza and Han. The Board analyzed the grounds for anticipation (Section 102) and obviousness (Section 103). Specifically regarding Han, the Petitioner failed to demonstrate that the reference disclosed the required 'second request' limitation in the recited arrangement, and its attempts to modify the claim were deemed illogical. Similarly, concerning Centonza, the petitioner could not show disclosure of a 'second request' as most cited messages were merely acknowledgements. Consequently, the Board denied institution because AT&T Services Inc. failed to demonstrate a reasonable likelihood of prevailing on any ground.
