Forensic Engineering

The background of a forensic engineering expert witness will vary greatly depending on the product and technology involved in a case. In general, a forensic engineering expert witness has an engineering discipline degree (i.e., mechanical engineering, materials engineering, civil engineering, structural engineering, or electrical engineering), along with extensive experience in forensic engineering, accident reconstruction, and/or laboratory testing. In a high-profile case, or litigation involving a significant financial stake, a law firm may require a forensic expert with prior expert testimony experience.

The primary purpose of a forensic engineering investigation is to locate the cause of a failure, assist in an accident investigation, or to investigate intellectual property infringement claims. Cahn Litigation Services most often works on cases requiring forensic engineering expertise that revolve around product liability and patent infringement matters. Clients may also seek a licensed professional engineer for pre-litigation engineering analysis work. Forensic engineering services in support of litigation could include product testing and failure analysis, reverse engineering, expert report preparation, depositions, expert opinion, and/or courtroom testimony.

Representing the plaintiff or defendant, when the need for a forensic investigation arises, top litigation firms call on Cahn Litigation Services.
