Narrative Opinion Summary
The case revolves around a motion filed by the University of South Florida Board of Trustees (USF) to amend pleadings under Federal Rule of Civil Procedure 15(b)(2) to include a counterclaim asserting ownership of certain patents. These patents were initially claimed by Alzheimer’s Institute of America (AIA) in a patent infringement action against Avid Radiopharmaceuticals and the University of Pennsylvania. USF sought a declaration of ownership based on the employment of the inventor at USF during the invention's conception but faced opposition from AIA, which argued it did not consent to litigate ownership issues and would be prejudiced by the amendment. The court had previously acknowledged USF's potential ownership but required a trial due to contested inventorship facts. Ultimately, the court denied USF’s motion to amend, concluding that the issue of ownership was not fully litigated by consent and that allowing the amendment would prejudice AIA, who was prevented from asserting certain defenses at trial. The decision underscores the importance of consent and the prohibition of prejudice in amending pleadings, as well as the complexities involved in establishing patent ownership rights when multiple affiliations and inventors are involved.

Trial by Consent for Unpleaded Issuessubscribe to see similar legal issues
Application: The court evaluated whether USF's ownership claims were tried by consent, considering recognition of the issue, lack of objection to evidence, and potential prejudice to AIA, ultimately concluding the issue was not fully litigated by consent.
Reasoning: Determining implied consent involves three factors: (1) whether the parties recognized the unpleaded issue during trial, (2) whether the opposing party acquiesced by not objecting to evidence related to the issue, and (3) whether the opposing party faced prejudice in responding to the issue.
