Short Summary
The PTAB found that the claims of the voltage regulator are unpatentable under § 103 based on a combination of Al-Shyoukh and Ivanov. The Board adopted Petitioner's interpretation of key terms, including finding 'gm enhanced' synonymous with 'gm boost.'
Detailed Summary
Petitioner successfully demonstrated that claims 1-18 were obvious over the combination of Al-Shyoukh (LDO with current buffer compensation) and Ivanov (fast disable/enable bias control). The Board adopted Petitioner’s interpretation that 'gm enhanced' is synonymous with 'gm boost,' and found credible testimony supporting the structural disclosure of a biasing circuit in Al-Shyoukh necessary for gm-boost. This finding resulted in the claims being held unpatentable under 35 U.S.C. § 103, rejecting the Patent Owner’s arguments regarding claim scope and enablement.
