Case Brief Summary & Legal Analysis
tl;dr: A professor sued his former employer, Duke University, for patent infringement. The court rejected Duke’s “experimental use” defense, holding that research furthering the university’s legitimate business objectives—even if non-profit—constitutes infringement and is not merely for “amusement, idle curiosity, or philosophical inquiry.”
Legal Significance: This case significantly narrowed the common law experimental use defense in patent law, holding that it does not immunize activities, even by non-profits, that are in furtherance of the alleged infringer’s legitimate business interests, such as enhancing prestige and attracting research grants.

Case Facts & Court Holding
Key Facts & Case Background
Dr. John M.J. Madey, a research professor, owned two patents related to free-electron laser (FEL) technology. After Duke University recruited him from Stanford, he established an FEL research lab at Duke, which housed equipment practicing his patents. Following a dispute, Duke removed Madey as director of the lab, and he subsequently resigned his professorship. Duke, however, continued to operate the patented equipment in the lab for research purposes. Madey sued Duke for patent infringement. Duke moved for summary judgment, arguing that its use of the patented technology was protected by the common law experimental use defense because its activities were non-commercial and for academic research purposes, consistent with its status as a non-profit educational institution. The district court agreed with Duke, holding that the experimental use defense applied because Duke’s use was not for definite, cognizable, and substantial commercial purposes. The district court granted summary judgment in favor of Duke, and Madey appealed.
Court Holding & Legal Precedent
Issue: Does the common law experimental use defense excuse a research university’s unlicensed use of a patented invention when that use, while not directly commercial, furthers the university’s legitimate business objectives of educating students, enhancing its reputation, and attracting research grants?
No. The court reversed the summary judgment for Duke, holding that the Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
