Detailed Summary

The Board concluded that the challenged claims are unpatentable over various combinations of prior art, including Baarman392, Partovi, Onishi, and Flowerdew. The key finding was that a Person Having Ordinary Skill in the Art (POSITA) would be motivated to combine general teachings—such as alignment from Flowerdew applied to Onishi's inductively coupled system—to achieve optimization. Furthermore, the Board adopted a narrow construction for 'substantially different,' limiting it to frequencies within near-linear regions of the frequency-amplitude graph.
