An IP expert witness (intellectual property) is a professional with specialized knowledge and experience in matters who provides independent expert opinions in litigation, arbitration, investigations, licensing disputes, and business disputes involving intangible assets.

IP expert witnesses help courts, attorneys, and organizations understand advanced issues involving patents, trademarks, copyrights, trade secrets, licensing, technology, brand value, and intellectual property damages.

Testimony consultants and trial testifying services providers do not decide who wins a case. Instead, they provide technical, financial, industry, or market analysis to help judges and juries understand complicated IP-related issues.
