U.S. Patents at the NYS Library

PTRC: Patent and Trademark Resource Center

The New York State Library has been a United States Patent and Trademark Resource Centerexternal link since 1871.

The Library's collection includes nearly everything the USPTO has published and distributed, ranging from early material in paper, through microforms, CD/DVDs and up to their current online databases. The collection also includes many commercially published resources. You can use the patent collection for both patentability searches and historical inquiries.

Most of the U.S. patent collection is housed on the 7th Floor of the State Library.

The public is welcome to visit the Library and use the U.S. Patent collection. The State Library has trained staff who will assist you in learning to use these tools. Appointments are not required to use the collection but are recommended if you would like assistance. You can make an appointment by calling 518-474-5355 or by sending an e-mail message.

State Library staff are not, however, patent attorneys or registered agents, and can not:

  • provide legal advice,
  • interpret your search results or strategies, or
  • provide opinions on the viability of a patent application.
