Narrative Opinion Summary
This case involves a patent infringement dispute between American Home Products Corporation (AHP) and Johnson & Johnson (J&J) over U.S. Patent No. 4,002,746, related to contraceptive methods. The U.S. District Court for the Eastern District of Pennsylvania ruled in favor of J&J, finding no infringement. AHP, the patent's exclusive licensee, alleged that J&J's product, norgestimate, infringed under the doctrine of equivalents. The district court initially granted AHP a preliminary injunction, which was later vacated by the appellate court due to insufficient evidence supporting AHP's claims. The court also denied J&J's summary judgment motion based on res judicata. A jury ultimately ruled against AHP, finding no infringement and favoring J&J on an unfair competition counterclaim. On appeal, AHP argued errors in jury instructions and trial procedure, but the appellate court affirmed the lower court's decisions, citing no abuse of discretion or substantial prejudice. The case highlights the application of the doctrine of equivalents, the Noerr-Pennington doctrine in unfair competition, and procedural standards in patent litigation.
