Computer hardware expert witness candidates typically have extensive experience and expertise in electrical engineering, computer engineering, and/or computer science. Computer hardware engineers need to understand the interconnection between hardware and software. The lead attorney may request a technologist with previous expert witness experience, but this is not always a requirement. An expert witness needs to not only have the appropriate substantive expertise, but should also possess the ability to explain evidence to lay people, including a judge and jury.

A computer hardware expert witness could be engaged to provide expert witness services for intellectual property matters, such as a patent infringement litigation or a trade secret dispute. A forensic expert has experience reverse engineering components to prove (or disprove) intellectual property infringement or theft. A computer hardware expert could also be called in on legal matters to consult on technical issues, which could require computer forensic engineering work. A computer hardware expert witness might provide testimony in a torts matter like personal injury or a product liability case. In addition, lead counsel may seek a computer expert for pre-litigation consulting work. Litigation support by a computer hardware expert witness could include computer forensics work, expert report preparation, expert opinion, and courtroom testimony. Whether the case involves:
