With a client list that is evenly balanced between plaintiffs and defendants, Ocean Tomo’s financial testimony professionals have industry-leading experience across all types of disputes and are particularly skilled in the determination of damages in matters involving intellectual property (IP). Testifying experts have decades of litigation analysis experience, benefiting clients when they evaluate complex financial data, qualitative facts, supporting testimony, and damages-related case law.
Ocean Tomo experts are routinely qualified in U.S. District Courts, U.S. Bankruptcy Courts, U.S. Tax Court, U.S. Court of Federal Claims, state courts, the U.S. Patent and Trademark Office Patent Trial and Appeal Board, international courts, and arbitration tribunals on questions relating to intellectual property economics. Ocean Tomo experts are known for a “teaching” – as opposed to “telling” – approach of testimony. Rather than only providing a judge or jury with an opinion, experts communicate the key facts and relevant theories in a clear and logical manner.
