Short Summary
The PTAB found all nine challenged claims unpatentable over the combination of prior art references Giobbi '157, Giobbi '139, and Dua. The Board specifically rejected arguments regarding § 112(f) limitations, confirming that key terms like 'PDK' and 'RDC' convey definite structure to a POSITA.
Detailed Summary
In this Final Written Decision, the Patent Trial and Appeal Board (PTAB) ruled in favor of the Petitioner, Microsoft Corporation, finding all nine challenged claims unpatentable over the combination of Giobbi ’157, Giobbi ’139, and Dua. The Board addressed arguments concerning 35 U.S.C. § 112(f), concluding that terms such as 'PDK' and 'RDC' conveyed sufficient definite structure rather than being means-plus-function limitations. Furthermore, the Board adopted the Petitioner’s position on obviousness (103), finding that the combination of the cited references taught specific elements of the claimed hybrid device, including integrated RDC functionality and signal line coupling.
