A power electronics expert witness is typically an electrical engineer with an advanced degree and extensive experience. Over the years, Cahn Litigation Services has been approached by multiple attorney clients to locate expert witnesses, on behalf of either the plaintiff or defendant, that can support matters involving power electronics. The chosen expert witness may be a member of an industry organization such as the IEEE.
A power electronics 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 expert witness testimony, as well as other expert witness services such as a prior art search, failure analysis, 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 electronics engineer expert witness needs to not only have expertise, a technical expert witness must possess the ability to explain technical evidence to lay people, including a jury. In addition, clients may seek a subject matter expert in electrical engineering for pre-litigation consultant work.
Whether the case involves a power supply, power converters, industrial automation motor drive, output voltage, power systems, a power electronic device, or analog circuits, 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.
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.
