Product Design Expert Witnesses

Start Product Design Expert Search

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). Cahn Litigation Services is often called upon to locate expert witnesses that can support product design matters to present demonstrative evidence to support a case on behalf of the plaintiff or defendant.

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. Litigation support by a product design expert witness could include product testing, forensic engineering, expert report preparation, expert witness testimony, and trial testimony. In a high-profile case, or litigation involving a significant financial stake, counsel may request an engineer with prior expert witness experience. 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. In addition, clients may seek a product design subject matter expert for pre-litigation consulting work.

Whether the case involves product failure, control systemsmedical device prototyping, forklift patent litigation, or human factors design, Cahn Litigation Services has the experience required to turn an engineering expert witness search around quickly and provide candidates with the right balance of expertise and testimony to support each unique project and its nuances.
