Singapore Treaty on the Law of Trademarks

The Singapore Treaty on the Law of Trademarks was adopted in Singapore on 28 March 2006. It entered into force on 16 March 2009, following the ratification or accession of ten countries, namely Singapore, Switzerland, Bulgaria, Romania, Denmark, Latvia, Kyrgyzstan, United States, Moldova, and Australia. The treaty establishes common standards for procedural aspects of trademark registration and licensing.

The treaty was built on the Trademark Law Treaty of 1994 (TLT), however the Singapore Treaty was meant to have a wider scope of application and addresses more recent developments in the field of communication technologies.

As of May 2023, there are 54 contracting parties to the treaty, which includes 52 states plus the African Intellectual Property Organization and the Benelux Organization for Intellectual Property.
