Trademark Search Assistance

  • A search of federally registered and pending trademarks is recommended for anyone seeking to name a service or product. This search is helpful to determine if someone else has already obtained protection for the name you plan to use in commerce. See Basic Facts About Trademarks.
  • Preliminary trademark research can be done via the U.S. Patent and Trademark Office's TESS database. For search assistance, please contact us at (405) 744-6546.
  • TESS includes federally registered and pending trademarks only; it does not include state registered or common-law marks.
  • For a complete search (federal, state, and common-law marks), please contact a trademark attorney or the Research Wizard service at the Tulsa City County Library (918) 596-7991.
  • For information on filing at the federal level see the Trademark Information Network.
