The Patent and Trademark Resource Center (PTRC) is a public service of Fogler Library in partnership with the U. S. Patent and Trademark Office (USPTO). Fogler Library has been a PTRC since 1993. We work closely with the Patent and Trademark Resource Center Program Office. They provide substantial online, printed and training resources to the Fogler PTRC. We also work with other PTRC libraries around the U.S. See the association web page: Patent and Trademark Depository Library Association.

Please note: 

While library staff are happy to provide assistance with your search, we cannot guarantee search results or offer legal advice. We cannot file applications or determine if a patent or trademark will be approved by the USPTO. We are not likely to be familiar with mechanical, electrical, chemical or other technologies relating to your search. Additionally, we are not trained or licensed legal professionals. This means that we are not able to advise you regarding any legal matters, including whether or not your invention is patentable, nor can we provide legal assistance for you. A database of registered patent attorneys is available on the USPTO Web site.
PTRCs are NEITHER REQUIRED NOR ENCOURAGED to conduct patent and trademark searches for their patrons as that activity may be interpreted as rendering a judgment or opinion.
PTRCs ARE REQUIRED to instruct patrons in the use of the search tools available at the PTRCs for patrons conducting their own patent and trademark searches.

You are encouraged to call in advance to schedule a training session with the PTRC Representative. Call (207) 581-1678.  


The best time to visit the PTRC is when Science and Engineering Center staff are available. Check the library hours homepage for building hours and holiday closures.
