Physics Expert Witnesses

Technology companies, manufacturers, and research institutions face litigation whenever a product’s underlying physical principles, performance claims, or patented technology are challenged in a commercial or intellectual property dispute. These matters commonly involve patent infringement and validity disputes concerning devices built on optical, nuclear, or materials-science principles, product liability claims involving semiconductors or medical devices, and contract disputes over whether a delivered technology met agreed performance specifications. Because physics-based disputes often involve underlying scientific principles that are not intuitive to a lay jury, the central issue is typically whether the physical behavior of the technology supports the performance or infringement claims being made. Presenting that analysis persuasively requires an expert who can translate advanced physics into terms a judge or jury can evaluate.

A physics expert analyzes the underlying scientific principles, test data, and design specifications of a product or process to determine whether it functioned as claimed and whether any allegedly infringing technology falls within the scope of an asserted patent. That analysis often distinguishes between a genuine engineering or design flaw and an unrelated cause of failure, which is central to liability determinations in product cases. In patent litigation, the expert’s technical comparison of accused and claimed technology directly supports infringement, validity, and damages positions. Because physics-based evidence can be highly technical, the expert’s ability to explain complex phenomena clearly also shapes litigation strategy and the effectiveness of trial testimony.

Because physics disputes frequently hinge on advanced technical concepts, selecting an expert with both deep subject-matter expertise and courtroom communication skills is critical to a persuasive case. The experts we can provide include physics professors from leading research universities and industry scientists with backgrounds spanning optics, nuclear physics, materials science, and semiconductor technology, many of whom have testified in patent and product liability matters. Round Table Group has completed more than 75,000 expert searches for litigators, and we draw on that experience to match counsel with physics experts whose specific technical background fits the dispute.
