Where can I find current classification information for U.S. patents?
The MPEP 902.03 provides several resources for finding current classification information for U.S. patents:
- Patent Classification Home Page: Available at www.uspto.gov/Classification. This site serves as a clearinghouse for classification information published in HTML and PDF formats.
