Case: Patents/Obviousness (P.T.A.B.)

The Patent Trial and Appeal Board said that challenged claims of Infineon Technologies Americas Corp.'s patent directed to a merged gate transistor with two gates, each capacitively coupled to the semiconductor element, aren’t unpatentable as obvious over prior art. According to the board, the challenged claims aren’t obvious over various combinations of prior art, including prior art that relates to amplifier circuits utilizing field plated transistors, and to an enhancement mode metal oxide semiconductor field effect transistor formed from a Group-III nitride compound semiconductor.
