Short Summary
The PTAB cancelled original claims (1-10) but granted substitute claims (11-19) after a Patent Owner's Motion to Amend. The Board found the Petitioner failed to demonstrate motivation to combine prior art references, thus overcoming obviousness challenges under 35 U.S.C. § 103.
Detailed Summary
In this Final Written Decision, the PTAB cancelled original claims 1-10 but subsequently granted substitute claims 11-19 following a Patent Owner's Motion to Amend. The core dispute centered on obviousness (35 U.S.C. § 103) over prior art references Torrence and Piepho. While the Petitioner challenged these substitute claims, the Board found that the Petitioner failed to establish sufficient motivation to combine the references to teach the claimed tapered shaft limitation of claim 11. Furthermore, the Board addressed a written description challenge regarding 'freely rotatable,' confirming an ordinary skilled artisan would understand possession based on mechanical context.
