The Secretary of State is the filing agent for Trademarks, Emblems, and Name Registrations under the laws of South Dakota. Hopefully the following information will assist you when filing your trademark, emblem, or farm/ranch/home name registration.
A trademark protects the name of a business or product, a patent protects an invention and a copyright protects an original artistic or literary work.
The Secretary of State does not process copyrights, patents or US trademarks. The telephone numbers for those offices are:
US Patent & Trademark Office: 1-800-786-9199 or 571-272-1000 local
US Copyright Office: 1-877-476-0778 or 202-707-3000 local
We have tried to make the trademark application, renewal, and assignment applications easy to understand so that you can complete them in a short amount of time. Feel free to contact my staff with any questions or concerns you have regarding the trademark application process. The Trademark Administrator can be reached through email at firstname.lastname@example.org or call 605-773-2797.
