Lanham Act expert witness candidates typically have backgrounds in consumer confusion, trademark infringement, survey research, and/or intellectual property law. In a high-profile case, or litigation involving a significant financial stake, a law firm may require a testifying expert with prior expert witness testimony experience.

The Lanham Act of 1946 is the primary federal trademark statute of U.S. law that protects the owner of a registered mark against the use of similar marks if deemed likely to cause consumer confusion. An intellectual property protection program stops others from using an owner’s intellectual property (trademark, trade dress, trade secret, patent, copyright) without a licensing agreement. The Lanham Act trademark law allows action in a state or federal court to request monetary relief or a court order (injunction) to stop use of the accused mark.
