Patent and Trademark Resource Center: Home

Wright State University Libraries maintain a Patent and Trademark Resource Center (PTRC) in the Paul Laurence Dunbar Library.  As an official PTRC of the United States Patent and Trademark Office (USPTO) we have a formal agreement to provide assistance to the general public in the use of patent and trademark resources provided by the USPTO. 

Recognizing that intellectual property research is a complex endeavor with important legal and financial implications, our services are designed to support the individual or corporate/legal researcher's efforts to conduct self-directed and preliminary research.

Library staff cannot offer legal advice, conduct searches, assist in writing applications, guarantee completeness of searches, or advise on ideas. All final research, regarding intellectual property determinations, should be done in consultation with proper intellectual property legal professionals.

The Reference staff will make every effort to protect the confidentiality and privacy of researchers.

Here is a spreadsheet of Miami Valley Inventors for the years 1814 to 1873. The spreadsheet contains 1800+ patent document numbers and 4000 individual names, some with historical notes. If indicated on the patent, assignment information and attorneys are also included in the record.

Counties: Butler, Champaign, Clark, Darke, Greene, Logan, Miami, Montgomery, Preble, Shelby, and Warren.

Cities: Dayton, Springfield, Xenia, Piqua, Troy, Sidney, Tipp City, Bellefontaine, Greenville, Hamilton, Middletown, Urbana, Oxford, Yellow Springs, and numerous smaller villages and localities.

If you are a first-time researcher it is recommended you make an appointment between 9 am and 4 pm Monday through Friday.  If those times are inconvenient arrangements can be made for other times.

Check the University Libraries online calendar for hours.
