What is a machinery expert witness?

Machinery expert witness candidates are typically licensed professional engineers with backgrounds in electrical engineering, mechanical engineering (BSME), equipment appraisal, structural engineering, and/or industrial design. The chosen expert could be 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). Machinery experts should also be familiar with applicable OSHA regulations. An engineering expert witness must not only have technical expertise, but also possess the ability to explain technology to lay people.

What types of cases require a machinery expert witness?

Frequently, matters requiring machinery 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 witness might also provide testimony in a torts matter like personal injury, a product liability case or an industrial accident investigation.

Machinery expert witness case examples

Cahn Litigation Services has search for machinery experts to support litigation on many occasions. Matter have encompassed:

• machine guarding evaluation for insurance companies,
• human factors,
• Certified Fire & Explosion Investigator (CFEI) to support a warehouse investigation,
• metallurgical analysis,
• aerial lifts,
• forklift accident reconstruction in New York,
• electrician assessment of an industrial equipment electrocution case,
• construction equipment breach of contract,
• New Jersey manufacturing equipment safety standards auditing, or
• workplace safety.

What litigation support work might a machinery expert witness be expected to perform?

Litigation support by a machinery expert witness could include forensic engineering, research and authoring expert reports, providing expert opinions, and expert testimony at deposition and at trial. In addition, a plaintiff may seek a machinery expert for pre-litigation consulting services. In some instances, counsel may request an expert with prior expert witness testimony experience.

Cahn Litigation Services has the experience required to turn a search for a machinery expert witness around quickly, providing the right balance of expertise and testimony experience.
