Patent expert witness candidates typically have extensive experience in patent law, economic damages, and/or as a patent examiner. Depending on the specifics of the case, subject matter experts in software, mechanical engineering, or electrical engineering may be called upon to address technical issues. In a high-profile case, or litigation involving a significant financial stake, a patent attorney may require a testifying expert with prior trial experience. An expert witness must be able to explain technology and complex situations to a judge and jury, as well as be able to withstand the scrutiny of a cross-examination.
An intellectual property protection program stops others from using an owner’s intellectual property (e.g., trademark infringement, trade secret, trade dress, patent protection, copyright infringement) without a licensing agreement. A U.S. patent, issued by the U.S. Patent & Trademark Office (USPTO), provides the right to exclude others from making, using, or selling an invention for a period of years, in exchange for publishing an enabling public disclosure of the invention.
Litigation support by a patent infringement expert witness could include research, an expert report, prior art searches, expert opinion, claim chart preparation, and expert testimony in court. An economic damages expert is often called on to opine on lost profits and damages analysis occurring from patent infringement. From semiconductors to software, Cahn Litigation Services has placed patent professionals to provide expert witness services for a wide variety of legal issues, including:
