Ultra-Precision Manufacturing v. Ford Motor Co.

Ultra-Precision, during a non-confidential relationship and without claiming trade secret, solved a problem with one of Ford's air compressors, which Ford later incorporated into its vehicles. Ultra-Precision sought restitution through an unjust enrichment claim under Michigan law. The CAFC found that Michigan law was preempted by Federal patent law when the effect of the unjust enrichment claim would result in a patent-like royalty for the claimant.
