Machine Design Expert Witnesses

Start Machine Design Expert Search

Machine design expert witness candidates are typically licensed professional engineers with backgrounds and expertise in electrical engineering, mechanical engineering, product design, structural engineering, and/or industrial design. The chosen expert is often a member of an industry or technical organization, such as the American Society of Mechanical Engineers (ASME), IEEE, or the National Tooling & Machining Association (NTMA).

Frequently, matters requiring machine design expert witness services involve intellectual property, such as patent infringement litigation, inter partes review or trade secret disputes. A forensic expert can reverse engineer components to prove (or disprove) intellectual property infringement or theft. A machine design expert could also be called in on breach of contract disputes to consult on technical issues, which could require forensic engineering work. A machine design expert witness might also provide testimony in a torts matter like personal injury or a product liability case involving the failure analysis of industrial equipment, construction equipment, or a medical device.

Litigation support by a machine design expert witness could include reverse engineering, an expert report, an expert opinion, and expert testimony at a trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a mechanical engineer with prior expert witness experience. An engineering expert witness needs to not only have technical expertise but must possess the ability to explain technology to lay people. In addition, clients may seek a mechanical engineering expert witness for pre-litigation consulting work.

Whether the case involves vehicles, appliances, farm machinery, machine tools, factory automation systems, robots, or anything in between, Cahn Litigation Services has the experience required to turn an expert witness search around quickly and provide the right balance of expertise and testimony to support each unique project.
