Manufacturing expert witness candidates are typically licensed professional engineers with extensive experience and areas of expertise in mechanical engineeringindustrial engineering, civil engineering, structural engineering, automotive engineering, consumer product design, electronics manufacturing, electrical engineering, biomechanics, and/or the manufacturing process. A manufacturing expert witnesses must also have a solid understanding of the global supply chain, procurement, and sourcing procedures. The chosen expert may be designated as a Certified Safety Professional (CSP) or Certified Manufacturing Engineer (CMfgE), and may be associated with an industry organization such as SME or CIRP.

What types of legal cases use a manufacturing engineer expert witness?

An expert in manufacturing 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). An engineer with specific knowledge in manufacturing might provide expert opinion in a matter such as a product liability case, breach of contract, or provide testimony in a personal injury case. Litigation support could include expert witness services such as an expert report, failure analysisaccident investigation, forensic engineering, and expert witness testimony in the courtroom. In addition, a law firm may request an engineer for pre-litigation consulting services.
