Narrative Opinion Summary
The case involves an appeal by Frederic A. Stern against a summary judgment granted by the United States District Court for the Southern District of New York in favor of Columbia University and Laszlo Z. Bito. Stern claimed co-inventorship of U.S. Patent No. 4,599,353, concerning prostaglandins for treating glaucoma, asserting that his early research contributed to the patent's conception. However, the court ruled that Stern failed to provide clear and convincing evidence necessary for establishing co-inventorship, as mandated by patent law standards and precedents such as Eli Lilly Co. v. Aradigm Corp. The court also interpreted the patent claims to affirm Columbia's understanding of maintaining intraocular pressure without tachyphylaxis as a key element. Stern's additional state law claims were dismissed, as they relied on his unsuccessful co-inventorship contention. The Federal Circuit reviewed the case de novo, confirming the district court's decision, given the absence of disputed material facts. Consequently, the judgment in favor of Columbia was affirmed, dismissing Stern's claims and maintaining the integrity of the patent's original inventorship designation.
