Narrative Opinion Summary
This case involves an appeal by Ultra-Precision Manufacturing, Ltd. against Ford Motor Company, challenging a district court's decision that Ross Herron and Gary Beard were not joint inventors of U.S. Patent No. 5,236,312, and that Ultra-Precision's unjust enrichment claim was preempted by federal patent law. The appellate court affirmed the lower court's decisions, finding no abuse of discretion in allowing Ford to raise a preemption defense and determining that the district court's findings on inventorship were not clearly erroneous. The case arose from efforts in the 1980s to address noise and vibration issues in Ford's air conditioner compressor, leading to collaborative engineering efforts between Ford and Ultra-Precision. Ultra-Precision filed suit in 2001, alleging unjust enrichment, correction of inventorship, and other claims, but the district court held that the unjust enrichment claim was preempted, given the federal patent law's dominance in regulating patent-like protections for disclosed ideas. The court also ruled that Herron and Beard did not contribute to the inventive concepts of the '312 patent, and therefore could not be considered joint inventors. The Federal Circuit reviewed the waiver of defenses and preemption issues de novo, ultimately supporting the district court's conclusions and upholding its rulings.
