The Newark Public Library has been a Patent and Trademark Resource Center since 1906, one of two in New Jersey. The other is the Library of Science and Medicine, Rutgers University, in Piscataway, New Jersey.

Patent and trademark collections and services are located in the Reference department on the second floor. Resources are available in print and on microfilm, CD-ROM, DVD and web-based databases. 

Librarians are expert searchers who will provide information, assistance, and instruction in the use of resources. They cannot, however, provide legal interpretation or advice, which should be sought from a patent attorney. 

Although it is possible to conduct a patent search using Internet resources, doing so will not yield comprehensive results and so should be considered a preliminary investigation only. A complete patent search should be conducted in person at a Patent and Trademark Resource Center.
