By Memorandum Order entered by The Honorable Leonard P. Stark in Power Integrations, Inc. v. Fairchild Semiconductor Int’l, Inc. et al., Civil Action No. 04-1371-LPS (D.Del., December 8, 2017), the Court dismissed without prejudice U.S. Patent No. 6,229,366 (“the ‘366 patent”) from the action, which was filed more than a dozen years ago, given that the U.S. Patent and Trademark Office allowed amended claims during Fairchild’s ex parte reexamination, issued a reexamination certificate and the reexamination amendments effected a substantive change in claim scope. Thus, any cause of action predicated on the original claims of the ‘366 patent was extinguished when the reexamination certificate issued. Id. at *5.
