Hardware Design

A hardware design expert witness typically has expertise and a background in electrical engineering, mechanical engineering, product design, computer hardware, and/or computer science.

A hardware design engineer understands hardware components, such as a printed circuit board and integrated circuit, created for computers and other machines like a medical device. An electronic system may include an embedded system, a field programmable gate array (FPGA) coded in a hardware description language (such as Verilog or VHDL), and of course software. Product design engineers need to understand the interconnection between hardware and software; the embedded systems engineering industry increasingly solicits software engineers with a background in hardware design.

Often, matters requiring hardware design expert witness services involve intellectual property, such as patent infringement litigation, inter partes review or trade secret disputes. A forensic expert can reverse engineer components to prove (or disprove) intellectual property infringement or theft. A hardware design expert could also be called in on breach of contract disputes to consult on technical issues, which could require forensic engineering work. A hardware design expert witness might also provide testimony in a torts matter like personal injury or a product liability case involving the failure analysis of consumer electronics or a medical device.

Litigation support by a hardware design expert witness could include reverse engineering, expert reports, 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 testifying expert with prior expert witness experience. An expert witness needs to not only have expertise, an engineering expert witness must possess the ability to explain technology to lay people. In addition, clients may seek an industry expert for pre-litigation consulting work.
