USPTO USPC Data

This page includes current USPC classification data from the USPTO (https://patentsview.org/download/data-download-tables). These data come from ‘uspc_current’.

Below is a link to a folder that includes current USPC classifications for all patents granted from January 1976 through May 2015 (USPTO moved to CPC system on January 1, 2013). This folder includes nine different zip files. Files “uspc_mainclass_title.csv.zip” and “uspc_sub_class_title.csv.zip” contain titles for USPC main classes and subclasses. For ease of download and ease of importing, files are divided by patent number. File “uspc_non_utility.csv.zip” includes all non-utility patents. File “uspc_5m.csv.zip” includes all patents issued beginning January 1976 through patent number 5,000,000. File “uspc_6m.csv.zip” includes all patents between patent number 5,000,001 and patent number 6,000,000. Etc, etc.

Each file contains the following columns:

Variable	Description
patnum	Patent number
uspc_main_class	USPC main classification
uspc_sub_class	USPC sub-classification
uspc_sequence	Patent-level position within USPC classifications
