Patent Search Guides

The Patent Librarian (Michael White) has created two guides to assist in patent searching: U.S. Patent Classification - Classes by Title and U.S. Patent Number Guide.

From Michael White:

Both guides are based on the laminated "quick study" guides sold in college bookstores and shops. The classes by title guide is simply an alphabetical list of current US classes. The group symbols that appear after each title are based on the placement of the class or its subclasses in the "Classes Within the U.S. Patent Classification Arranged by Related Subjects," which is part of the manual of Classification. Cross-reference classes are also noted.

The patent number guide is compiled from many sources including the Manual of Patent Examining Procedure, USPTO web site, WIPO standards, Official Gazette and National Archives publications.
