User Experience

An expert witness in the user experience field will typically provide his or her expertise in intellectual property matters. Such matters may include a patent infringement case in district court or federal court, an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), a trade secret dispute, or a patent case or proceeding in the International Trade Commission (ITC). Litigation support by a user experience subject matter expert could include opinion testimony, expert report, expert opinion, and expert witness testimony at trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with prior expert witness testimony experience. In addition, clients may seek a qualified expert for pre-litigation consultant work.
