General Information

Patent and Trademark Resource Center

The Smithtown Library is an officially-designated Patent and Trademark Resource Center (PTRC), part of a nationwide library network maintained by the U.S. Patent and Trademark Office (USPTO). PTRCs disseminate patent and trademark information and support the public's diverse intellectual property needs. Smithtown Library staff are not able to conduct patent searches and cannot provide legal advice. The Library's staff can, however, assist patrons in performing their own patent searches and with finding and using other research materials.

As a PTRC, The Smithtown Library offers:

• Free access to patent and trademark documents in various formats.

• Access to the PubWest database for patent searching.

• Access to the PubEast database for patent searching. 

• Acces to Plant Patents in hardcopy format. 

• Resources for historical patent research.

• Patent searching guides and other reference materials on intellectual property.

• USPTO-trained staff.

PTRC resources are located in the Main Building (Smithtown) only. An appointment is recommended. Call the Reference Department at (631) 360-2480 x128 to make an appointment.
