Patent Expert Witnesses
Patent litigation arises when parties disagree over whether a product or process falls within the scope of a patent's claims, whether the claimed invention was truly novel and non-obvious over the prior art, or whether a patent should be enforceable at all given its prosecution history. These disputes frequently involve dense technical subject matter, ranging from semiconductor architectures to pharmaceutical formulations to software algorithms, that must be translated into terms a court or jury can evaluate against the legal standards for infringement and validity. Standard-essential patent disputes and cross-border patent races in fast-moving fields add further complexity, as parties contest not only technical scope but also licensing obligations. Attorneys need independent, field-specific expertise to establish what the claims actually cover and how the accused technology compares.
A patent expert walks through claim construction issues from a technical standpoint, compares the accused product or process against each disputed claim element, and situates the invention against the prior art to address novelty and obviousness. This technical grounding supports infringement and validity positions and also informs damages, since a reasonable royalty or lost profits analysis often depends on how central the patented feature is to the accused product. In prosecution-related disputes, the expert can address whether disclosures to the patent office met the applicable standard of care, supporting or rebutting claims of inequitable conduct. Because Daubert challenges in patent cases increasingly turn on the rigor of an expert's technical methodology, attorneys benefit from experts whose approach can withstand scrutiny at every stage of litigation.
The technical breadth of patent litigation, spanning everything from medical devices to microchips, means the right expert must combine deep subject-matter knowledge with the ability to communicate that knowledge clearly under examination. Round Table Group's patent network includes scholars and industry professionals who have worked with organizations such as Boeing, IBM, Lockheed Martin, and Pfizer, along with patent prosecution attorneys, registered patent agents, and named inventors with extensive claim drafting and licensing experience. With more than 75,000 expert searches completed for litigators, we know how to identify the specific technical and legal combination a given patent matter requires.
