Photonics Expert Witnesses

Start Photonics Expert Search

Depending on the specific technology and product, a photonics expert witness typically has an advanced degree and a background and expertise in electrical engineering, optical engineering, physics, materials engineering, and/or mechanical engineering. Cahn Litigation Services has been approached by numerous clients to locate expert witnesses, on behalf of either the plaintiff or defendant, that can support matters involving photonic technology. The expert witness chosen may be a member of an industry organization such as The Optical Society and/or IEEE. A photonics expert witness should have a deep understanding not only of the technology, but also of the photonic technology global market, market size, market growth, market share and competitive landscape.

A photonics expert witness could provide expertise in intellectual property matters such as a patent litigation in federal court or a trade secrets 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 deposition, expert testimony, a prior art search, an expert report, forensic engineering, and related consulting activities. In high profile cases, or litigation involving a significant financial stake, previous expert witness experience is often a requirement. An engineering expert witness needs to not only have expertise but must also possess the ability to explain the underlying substantive technology to lay people, including judge and jury. In addition, clients may seek a photonics expert for pre-litigation consulting work. Whether the case involves semiconductor devices, fiber optic cables, silicon photonics, diode lasers, optical systems, semiconductor manufacturing, light emitting diode (LED), photonic integrated circuits, imaging or thin films, Cahn Litigation Services has the experience required to turn an expert witness search around quickly and provide the right balance of expertise and testimony to support each unique project.
