A pre-application search for existing trademarks is the first step to take. If the trademark infringes the intellectual property rights of others or violates national laws, the trademark may be refused registration.

Before submitting an international application through the Madrid system, it is advisable to search for identical or similar marks already existing (or pending) in the target market.

Use this guide to learn how to search the WIPO’s Global Brand Database (WIPO’s Global Brand Database) before filing a trademark application and how to search the trademark registers of the national and regional trademarks.

  • Research identical or similar image marks using the image search function.
