Signal Processing Expert Witnesses

Start Signal Processing Expert Search

Signal processing expert witness candidates typically have an advanced degree, and expertise and extensive experience in electrical engineering, computer engineering, or computer science. A signal processing expert witness should have a deep understanding not only of signal processing technology, but also of the industry, market size, market share, market dynamics, market growth, market trends, and competitive landscape. The chosen expert witness may be a member of a technical industry organization such as the IEEE.

A signal processing expert witness could provide expertise in intellectual property matters, such as a patent litigation in federal court or a trade secret dispute. It could be a patent infringement case in the District Court, an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), or a patent case or proceeding in the International Trade Commission (ITC). An expert in signal processing technology might also provide testimony in a torts matter such as product liability. An expert witness needs to possess the ability to explain technology and evidence to lay people, such as a judge or juror. Litigation support by a signal processing expert witness could include a forensic investigation, reverse engineering, failure analysis, expert reports, expert opinion, and courtroom testimony. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with prior expert witness testimony experience. Clients may also seek an industry expert for pre-litigation consultant work.
