Intellectual Property Search

Click on the links in the drop down menu for various Intellectual Property searches. With these links, you may access the records of the Patent, Trademark, and Copyright Offices; conduct preliminary searches to determine the availability or existence of patents, trademarks, copyrights, and domain names; or find potential licensees and manufacturers. You can also see a listing of patents we have prepared for our clients.

These search engines, however, will allow only a basic search. For a comprehensive search, please contact us for assistance. Cislo & Thomas LLP cannot guarantee the results of any online searches you perform on your own.
