Highway Equipment Co., Inc. v. FECO, Ltd., 2006 U.S. App. LEXIS 28740 (Fed. Cir. Nov. 21, 2006)
Plaintiff sued for patent infringement, and defendant counter-claimed for wrongful termination of dealership. After the District Court granted plaintiff's motion for partial summary judgment on the counter-claim, plaintiff filed a covenant not to sue on its claim. As a result, the District Court dismissed plaintiff's claims with prejudice. Defendant then filed a motion for attorney's fees under 35 U.S.C. § 285, which authorizes fees for prevailing parties under "exceptional circumstances." The District Court found no exceptional circumstances and denied a fee award. Defendant appealed, and plaintiff argued that the District Court lacked subject matter jurisdiction to hear the fee request once the underlying matter was dismissed with prejudice based on plaintiff's covenant not to sue. The Federal Circuit held that "as a matter of patent law, the dismissal with prejudice, based on the covenant and granted pursuant to the district court's discretion under Rule 41(a)(2), has the necessary judicial imprimatur to constitute a judicially sanctioned change in the legal relationship of the parties, such that the district court properly could entertain [defendant's] fee claim under 35 U.S.C. § 285." The Court, however, upheld the District Court's finding that the case did not involve exceptional circumstances justifying a fee award.
