Justia Patents Opinion Summaries

A company specializing in hybrid electric aircraft technology filed suit in Washington state court against a major aerospace manufacturer and its investment affiliate, alleging misappropriation of trade secrets, breach of contract, and tortious interference, among other state law claims. The plaintiff asserted that the defendant improperly used its confidential information, including by incorporating aspects of the plaintiff’s technology into two patents obtained by the defendant. The plaintiff’s claims involved several theories and more than 30 alleged trade secrets.The aerospace manufacturer responded by counterclaiming for a declaratory judgment that its employees were the sole inventors of one of the patents in question. The case was removed to the United States District Court for the Western District of Washington based on this federal patent law counterclaim, and a second inventorship counterclaim was later added regarding another patent. The district court granted summary judgment in favor of the defendant on both patent inventorship counterclaims. The remainder of the plaintiff’s claims proceeded to a jury, which returned a verdict awarding the plaintiff over $92 million for trade secret misappropriation and tortious interference. However, the district court granted the defendant’s post-trial motion for judgment as a matter of law and conditionally granted a new trial, vacating the jury award.On appeal, the United States Court of Appeals for the Ninth Circuit reversed the district court’s post-trial rulings and remanded the case with instructions for reassignment to a different district judge. In a subsequent petition for rehearing, the defendant argued for the first time that appellate jurisdiction belonged exclusively to the Federal Circuit because the counterclaims were compulsory and arose under patent law. The Ninth Circuit held that the defendant’s counterclaims, though arising under federal patent law, were permissive—not compulsory—because they did not share the same operative facts as the plaintiff’s state law claims; thus, Ninth Circuit jurisdiction was proper. The court also held that the district court appropriately exercised supplemental jurisdiction over the state law claims, as they shared a common nucleus of operative fact with the federal counterclaims. The petition for rehearing was denied. View "ZUNUM AERO, INC. V. THE BOEING COMPANY" on Justia Law
