Graphics Expert Witnesses

What is a graphics expert witness?
Graphics expert witness candidates typically have backgrounds in computer science, forensic animation, graphic design, computer animation, and/or software engineering. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a graphics specialist with prior expert witness testimony experience.
What types of cases require a graphics expert witness?
Producing images on a computer is known as computer graphics. Computer graphics images are used for printed material as well as still and moving images for comic strips and animations. Computer graphics are heavily used in electronic games and are also essential for computer-aided engineering and design.
Matters requiring computer graphics technology expert witness services may involve patent infringement litigation, copyright or trade secret disputes, or forensic animation.
Graphics expert witness case examples
Exemplary cases have involved:
- litigation graphics for a personal injury case in New York City,
- 3D animation to support a San Francisco medical malpractice case,
- trial presentation software, and
- schematic piece of evidence.
What litigation support work might a graphics expert witness be expected to perform?
Litigation support by a graphics expert witness could include research and authoring expert reports, providing expert opinions, code reviews, art searches, and deposition/courtroom testimony. In addition, clients may seek a computer graphics expert witness for pre-litigation consulting work.
