Physics Expert Witnesses

Start Physics Expert Search

Depending on the specific technology and product, a physics expert witness typically has an advanced degree and extensive experience in physics, or a related engineering discipline. 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 physics. The expert witness chosen may be a member of an industry organization such as the American Physics Society, the American Institute of Physics and/or the IEEE.

A physics 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. A physics expert witness needs to not only have substantive expertise but must also possess the ability to explain technical evidence to lay people, including judge and jury. In addition, clients may seek a physics subject matter expert for pre-litigation consultant work.

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.
