Product Design Expert Witnesses

What is a product design expert witness?

Depending on the specific product involved in the case, product design expert witness candidates typically have extensive experience and areas of expertise in industrial design and/or an engineering discipline (i.e., systems engineering, electrical engineering, mechanical engineering, metallurgy). Product development expert witnesses may have experience in biomedical engineering, chemical engineering, medical devices, or consumer products. Product design expert witness candidates typically have advanced degrees (PhD, PE) and in a high-profile case, or litigation involving a significant financial stake, counsel may request an engineer with prior expert witness experience.

What types of cases require a product design expert witness?

Often, matters requiring product design expert witness services involve intellectual property, such as a patent infringement case or trade secrets dispute. A product design expert witness could also be instrumental in a product liability case. In addition, clients may seek a product design subject matter expert for pre-litigation consulting work.

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

Litigation support by a product design expert witness could include product testing, forensic engineering, research and authoring expert reports, expert witness testimony, and trial testimony. An expert witness needs to not only have expertise but must also possess the ability to explain the underlying technology and evidence to lay people, such as judges and jurors.

Whether the case involves product failure, control systems, medical device prototyping, forklift patent litigation, or human factors design, Cahn Litigation Services has the experience required to turn a search for a product design expert witness around quickly, providing the right balance of expertise and testimony experience.
