Where can you search for owners of patents, trademarks and copyrights?

Your question brings up a good idea! Unfortunately there isn’t one website where you can run a global search for all three. You’ll have to search each type of intellectual property (IP) one at a time. Here are some helpful, free search databases:


Patentscope – World Intellectual Property Organization (WIPO)’s database search

Global Patent Search Network (through the USPTO) – allows you to search US and China patents

Google Advanced Search – allows you to run a search that returns patents with the international classification

Espacenet – pretty decent worldwide search


Trademark Electronic Search System (TESS) – USPTO search

WIPO Global Brand Database – your best bet for an international search


U.S. Copyright Office search

Thomson Compumark – paid international copyright search

I hope this helped! If you need help searching beyond these databases then stop by LawTrades. We have numerous IP attorneys available to search even deeper to ensure you aren’t infringing. Stop by for a free no obligation price quote!
