Unregistered trade marks are provided some protection under Australian trademark law.
[2] Bangladeshi law, including Penal Code (1860), the Customs Act (1969), the Consumer's Right Protection Act (2009) and the Bangladesh Standard and Testing Institute Act of 2018 protect unregistered trademarks from infringement on the basis that it is an unfair business practice which deceives consumers and damages the reputation of trademark owners.
Unregistered trademarks which are well-known to consumers and strongly related the original user's goods and services are protected under the Unfair Competition Prevention Law.
[12] In those jurisdictions with limited protection to unregistered trademark owners, a common law trademark owner's remedies may be limited to injunctive relief (a court order for the defendant to cease and desist the infringement).
An unregistered trademark may receive protection under the federal "Lanham Act" (15 USC § 1125), which includes prohibition against commercial misrepresentation of source or origins of goods.
Unlike other trademark statutory provisions, a claim under the Lanham Act may permit a party to recover attorneys' fees and costs.
