What is a signal processing expert witness?

Signal processing expert witness candidates typically have an advanced degree and expertise in the analysis and manipulation of signals (such as sound, images, and electrical signals) and extensive experience in electrical engineering, computer engineering, or computer science. Digital signal processing (DSP) experts have specialized knowledge of signal processing using digital technology and algorithms to process signals. Expert witnesses 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. Signal processing experts may belong to a variety of organizations and associations depending on their specific area of expertise including the Institute of Electrical and Electronics Engineers (IEEE), the international Association for Pattern Recognition (IAPR), the International Association of Acoustics, Speech, and Signal Processing (IEEE-CASS), and/or the Signal Processing and Data Analysis (SPDA) section of the Society for Industrial and Applied Mathematics (SIAM).

What types of cases require a signal processing expert witness?

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).
