Monolithic Power Systems, Inc. v.Greenthread, LLC
Greenthread, LLC has filed a Request for Director Review challenging the PTAB’s claim construction in a power‑semiconductor patent owned by Monolithic Power Systems. The owner contends the Board’s construction mischaracterizes the claims and that the cited references do not teach the required carrier‑movement limitation.
Monolithic Power Systems, Inc. v.Greenthread, LLC
Monolithic Power Systems argues that the PTAB correctly applied the prosecution history to the ‘aid the movement of carriers’ limitation and that Greenthread’s Director Review request merely repeats arguments already rejected. The petitioner seeks denial of the request to preserve the invalidity finding.
Monolithic Power Systems, Inc. v.Greenthread, LLC
The PTAB instituted an IPR on claim 44 of Greenthread’s ’222 patent after finding a reasonable likelihood that Monolithic Power Systems would prevail, based on obviousness arguments over Onoda, Nishizawa, and Kawagoe.
Monolithic Power Systems, Inc. v.Greenthread, LLC
Monolithic Power Systems argues that Greenthread’s request for Director Review should be denied because the Board’s interpretation of the claim term “aid” was correct and the arguments have already been rejected in prior proceedings.
