Colorado State Archives Trademark Records
A trademark is a work, name, or symbol used to distinguish a corporation's products from their competitors'. Once filed with the state or federal government, the originator of the trademark may legally prevent anyone from using their mark or any very similar mark. In Colorado, trademarks are filed with the Secretary of State's Office. Trademarks in Colorado are valid for ten years and may be renewed for an additional decade if the mark is still actively being used. A few trademarks are posted at an on-line index. We also have another new page that has many samples in our digital archives section at: http://www.colorado.gov/dpa/doit/archives/digital/trademarks.htm. In addition, we have added Trademark records to our Historical Records Database as well as Incorporation recordings for almost 66,000 businesses operating in Colorado. The trademark records have the name of the person filing the trademark, the company as well as the product names. This is a great way to study Colorado's history as well as possibly find out more about your ancestors.
Trademark searches may be conducted personally at the State Archives or
you may request that a
staff member do the search for a fee. Address all inquiries to the Colorado State Archives.
For records after 1975, please contact the Colorado Secretary of State's Office, Commercial Recordings.
