        The Patent and Trademark Depository Library at Wichita State University has been a designated
        PTDL since
1991 and is the only PTDL in the state of Kansas.

        The Library receives copies of patents and trademarks issued by the U.S. Patent & Trademark
        Office, and maintains a collection of resources necessary for preliminary patent and trademark
        research.  In addition, the Library provides a state of the art computer workstation for searching
        patents issued from 1790 to to the current week of issue.  Users may access the USPTO web site
       or use the patent examiner systems Web-based Examiner Search Tool (WEST).     


Services we provide:

  • We offer assistance with PRELIMINARY patent searches (U.S.) and trademark searches (federal) by appointment.
  • To set an appointment, please call 316-978-5130 or e-mail Nan Myers, Librarian for Patents and Trademarks.
  • Consult a patent attorney for complete patent searching and for legal advice.

Patent websites:

Note: A complete, comprehensive patent search is difficult if not impossible to do using free, Internet accessible patent databases. The databases have limitations: coverage of only recent patents, partial text (or no text) of patents, no drawings, incomplete information, lack of sophisticated searching techniques, and dependence on keyword searching. A patent search on the Internet is a preliminary search only. For serious, comprehensive patent searching, use your local Patent and Trademark Depository Library.
