Start Mechanical Engineering Expert Search
What is a mechanical engineering expert witness?
Mechanical engineering expert witness candidates are typically licensed professional engineers with extensive experience and an advanced degree (e.g., a PhD) in mechanical engineering, industrial engineering, civil engineering, metallurgical engineering, structural engineering, biomechanics, automotive engineering, and/or human factors.
What types of cases require a mechanical engineering expert witness?
An expert in mechanical engineering could provide expertise in intellectual property matters, including patent infringement or a trade secret dispute. It could be an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), or a patent case or proceeding in the International Trade Commission (ITC). A mechanical engineer might provide expert opinion in a matter such as a product liability case, accident investigation, breach of contract, or provide testimony in a personal injury case.
