On-Board Diagnostics Expert Witnesses

Start On-Board Diagnostics Expert Search

On-board diagnostics expert witness candidates typically have extensive experience and knowledge in automotive engineering, electrical engineering, mechanical engineering, and/or vehicle manufacturing. An automotive engineer specializing in on-board diagnostics (OBD) may also have a background in sensor technology or safety. Cahn Litigation Services is frequently called upon by law firms, representing either the plaintiff or defendant, to locate an expert witness that can support automotive issues including those involving on-board diagnostics technology.

On-board diagnostic systems are in most cars on the road today. Originally used to diagnose engine problems for EPA emission standards, modern systems provide a standardized series of diagnostic trouble codes for comprehensive engine control and monitoring of parts of the chassis, accessory devices, and the diagnostic control network.

An on-board diagnostics expert witness could provide expertise in intellectual property matters, such as a patent litigation in federal court or a trade secret dispute. It could be a patent infringement case in the District Court, or a patent case or proceeding in the International Trade Commission (ITC). An automotive expert in OBD technology might also provide testimony in matters such as a product liability case.

Litigation support by an OBD expert witness could include an expert report, forensic engineering, expert opinion, and expert testimony at a trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a technical expert with prior expert witness experience. It is essential that an expert witness possess the ability to provide expert testimony in such a manner that a jury and judge can understand the factual evidence.
