Hardware Expert Witnesses

What is a hardware expert witness?

Hardware expert witness candidates typically have areas of expertise in electrical engineering, mechanical engineering, product design, computer hardware, and/or computer science. Hardware engineers need to understand the interconnection between hardware and software; the embedded systems engineering industry increasingly solicits software engineers with a background in hardware engineering.

What types of cases require a hardware expert witness?

A hardware expert witness could be engaged to provide expert witness services for intellectual property matters, such as a patent infringement litigation in federal court or a trade secret dispute. A forensic expert has experience reverse engineering components to prove (or disprove) intellectual property infringement or theft. A hardware expert could also be called in on breach of contract disputes to consult on technical issues, which could require computer forensic engineering work. A hardware expert witness might also provide testimony in a product liability case involving the failure analysis of a consumer electronics device.

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

Litigation support by a hardware expert witness could include reverse engineering, research and authoring expert reports, providing expert opinions, patent validity/invalidity arguments, and testimony a deposition and in the courtroom. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with previous experience.
