Optical communication, or optical telecommunication, is communication using light to transmit information. Cahn Litigation Services is called on by attorney clients to locate expert witnesses that can support matters involving communications technology, including optical communication. An optical communications expert witness typically has an advanced degree and extensive experience and expertise in electrical engineering, computer science, and/or software engineering – depending on the specific technology and product involved the case.
Cahn Litigation Services has completed numerous searches for expert witnesses with specific knowledge in optical technology, passive optical network, wireless communication, telecommunication systems, optical switching, image processing, signal processing, optical fiber, and nonlinear optics. Most often the expert witness chosen is member of an industry organization such as the Optical Society (OSA), the Fiber Optic Association, and/or IEEE. An optical communications expert witness should have a deep understanding not only of the technology, but also of the fiber optics market, market share, market size, and competitive landscape.
An optical communications expert witness could provide expertise in intellectual property matters — 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, or a patent case or proceeding in the International Trade Commission (ITC). In a litigation scenario, a technical expert can expect courtroom testimony, as well as other expert witness services such as depositions, expert testimony, an expert report, prior art search, forensic analysis, claim charts, and related consulting activities. In high profile cases, or litigation involving a significant financial stake, previous expert witness experience is often a requirement. An optical communications expert witness needs to not only have technical expertise, but should also possess the ability to explain technology and evidence to lay people, including a judge and jury. In addition, clients may seek an optical communication subject matter expert for pre-litigation expert consulting work.
Please Note: All Cahn Litigation expert witness searches are customized to attorneys' precise specifications and preferences. Attorneys are encouraged to discuss search parameters with a Cahn search specialist.
