Can the public access the same patent classification information as patent examiners?

Yes, the public can access much of the same patent classification information as patent examiners. According to MPEP 902.03(b):

“Examiners and the public are provided with access to identical information for the Index, schedules, and definitions.”

While some tools, like the Patent Classification Retrieval System (PCRS), are specifically for internal use, the public can access similar information through:

• The USPTO Patent Classification Home Page (www.uspto.gov/Classification)
• The USPTO Patent Full-Text and Image Database
• EAST and WEST tools available in the Patent Search Room at the USPTO

This ensures transparency and allows inventors, attorneys, and researchers to access comprehensive classification data for their patent searches and research.
