Information Services
Library reference staff can provide specific patent and trademark information when patent and trademark numbers are known. Generally, the complexity of patent and trademark searching necessitates a visit to the Library where the librarians can guide you in the use of the reference resources. Librarians are not attorneys and are unable to provide legal opinions or advice. (Policy G.12)

- all patents assigned to a class/subclass
