    • Carnival Corp. v. DeCurtis Corp. (S.D. Fl.). Vann was lead counsel for Carnival through summary judgment in this litigation involving breach of contract, patent infringement, trade secret, antitrust, and tort claims related to Carnival's novel OceanMedallion™ guest engagement system. The Orrick team led by Vann won summary judgment on all claims for damages asserted against Carnival  (antitrust, unfair competition, and tortious interference) as well as all claims that Carnival defrauded the Patent Office. Vann then was a member of the two trial teams that first obtained a $21 million jury verdict for breach of contract and patent infringement and then obtained an injunction in a separate bench trial in a different court. Vann cross-examined the opposing party’s CEO and COO at trial. The Orrick team’s victory in the first trial was recognized in Litigation Daily's Litigators of the Week feature. https://www.orrick.com/en/News/2023/03/Carnival-Corporation-Wins-21-Million-Judgment-in-Patent-Infringement-and-Breach-of-Contract-Trial
