What is Counterfeit?

A counterfeit product carries another company's trademark without authorisation.

Why it matters

Counterfeiting is a finding about a trademark, not about product quality or licensing, and Traceleaf only records it where a court or a regulator has said so.

Sources

Every claim on this page about a statute, an agency instrument or a tariff instrument rests on one of these, and each one is a document you can open. Where a claim could not be checked against a source, it was removed rather than hedged.

  1. 15 U.S.C. § 1127, Lanham Act definitions

    Defines a counterfeit as “a spurious mark which is identical with, or substantially indistinguishable from, a registered mark”, a finding about a mark, not about a product's quality or its licensing.
