What is an engineering expert witness?

Engineering expert witness candidates are typically licensed professional engineers with areas of expertise covering mechanical engineering, civil engineering, metallurgical engineering, electrical engineering, structural engineering, geotechnical engineering, biomechanics, automotive engineering, and/or forensic engineering. Engineering expert witnesses have advanced degrees (PE, PhD, MD) and years of experience in their specialty field.

What types of cases require an engineering expert witness?

An engineering expert 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 might provide expert opinion in a matter such as a product liability case, accident investigation, or provide testimony in a personal injury case.  

Engineering expert witness case examples

Engineering matters encompass a vast range of disciplines. Representative matters where Cahn Litigation Services has searched for experts include:

• consumer product intellectual property dispute,
• biomechanics products liability investigation,
• semiconductor reverse engineering,
• medical products liability on behalf of insurance companies,
• Connecticut engineering firm contract dispute arbitration,
• forensic engineering for patent infringement allegations,
• a civil engineer to opine on a construction defect for real estate development,
• structural engineering software analysis,
• failure analysis of automotive components,
• forklift personal injury case in New Jersey, and
• mechanical failure of industrial HVAC systems located in Florida.

The firm has an earned reputation for providing professional engineering candidates with the right balance of technical expertise and testimony for the job at hand.

What litigation support work might an engineering expert witness be expected to perform?

Litigation support could include expert witness services such as research and authoring expert reports, failure analyses, design defect analyses, accident reconstruction, forensic engineering, and expert witness testimony at deposition and in the courtroom. In addition, law firms may request an expert for pre-litigation consulting services.

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