Did you know there is a helpful and free online tool to search across multiple national trademark office databases? The World Intellectual Property Organization (WIPO) provides a free online search tool called the Global Brand Database, that searches across 12 national databases, including the entire USPTO collection, CIPO (Canada), Algeria, Australia, Israel, Oman, New Zealand, Philippines, Singapore, Egypt, Estonia, Morocco, Switzerland, and the United Arab Emirates, in addition to WIPO's own collection of international trademarks registered under the Madrid System.
In total, the Global Brand Database has over 15.7 million trademark and related records, making it the largest, free public resource for searching trademarks. Accordingly, this is a key resource to use when researching a domain name to see if there are any trademarks already registered which correspond to the domain name.
Although not entirely comprehensive - i.e. it does not search all registered trademarks all over the world - and also does not search for common law trademarks, it is nevertheless a great first step when looking into a domain name and potential trademark issues. In fact, some UDRP panelists may even expect a domain name registrant to have checked the Global Brand Database prior to registering a particular domain name, as was the case with one of the Panelists in the Bespoke.com case.
