Legal Definitions - counterfeit trademark

A counterfeit trademark is a spurious mark that is identical to, or substantially indistinguishable from, a registered trademark. This means that someone has created a fake version of a trademarked product or logo in order to deceive consumers into thinking they are buying the real thing.

For example, if someone creates a fake Nike logo and puts it on a pair of shoes, they are creating a counterfeit trademark. This is illegal and can result in legal action being taken against the person or company responsible.
