Dispute Summary
Monolithic Power Systems filed a Director Review request challenging the PTAB’s claim construction and obviousness finding for its MOSFET doping‑profile patent (U.S. 9,190,502). The petitioner argues the Board misinterpreted functional claim language and ignored district‑court rulings, asserting that the cited references do not teach the required carrier‑movement limitation.
