A search for registered US trade marks can be carried out on the USPTO website. Please note that only applied for and registered ‘federal marks’ are displayed.

For EU, GB and USA:
The TMView database records trade mark applications from the entire EU and various other countries, including the USA. Please note that only “federal marks” are registered.
