Patent Counts By Class By Year
Patents Granted: 1977 - 2015
A Patent Technology Monitoring Team Report

Description of the Report

Classes are major divisions of technology in the U.S. Patent Classification System (USPC). Each class is further divided into smaller divisions of technology called subclasses. The USPC currently contains approximately 475 total classes and 165,000 total subclasses. Copies of each patent are placed (classified) in those subclasses that have been identified as pertinent to the information disclosed in the patent. One, and only one, of these subclasses is designated as the "original classification" (OR), and the remainder (if any) are designated as "cross-reference classifications" (XR).

The "original" classification of a patent may be considered to be its "primary" classification. This classification need not correspond to any classification that was assigned to the patent at the time of issue since the classification system is continuously undergoing revision and since classifications that are assigned to patents are continuously updated to reflect these revisions. Counting patents by "original" classifications will ensure that each patent is counted only once. However, if a patent teaches more than one concept, e.g., table and chair, only one concept, e.g., table, will be counted. To ensure that all concepts are counted, patents should be counted in all of their classifications. Patent classifications used to produce this report are those assigned to patents as of December 31, 2015 . Please refer to the U.S. Patent and Trademark Office Manual of Patent Classification for further information regarding the patent classification system.

Please note that the U.S. Patent and Trademark Office has transitioned from the U.S. Patent Classification System (USPC) to the Cooperative Patent Classification System (CPC) and that USPC classifications generally are no longer available for U.S. utility patents that issued after early June, 2015. Therefore, in this report, USPC classifications for utility patents issuing after early June 2015 have been determined as a best estimate based on USPC classifications that were assigned to the associated patent applications during early processing stages and based on other information, as available. As a result of the transition to CPC, utility patents granted after early June 2015 have fewer USPC "cross-reference classifications" and often may have no "cross-reference classifications" associated with them. An effect of this change can be seen in the substantially reduced total count of annual "original" and "cross-reference classifications" for 2015 as compared to 2014 (table in Part II). About 90% of all patent documents granted by USPTO (i.e., including utility, design, plant, and reissue patents, statutory invention registrations, and defensive publications) are utility patent grants.

This report counts all patent documents including utility, design, plant, and reissue patents as well as statutory invention registrations and defensive publications.

Report Printing and the Use of Spreadsheet Software

This report can be printed from an Internet browser - for such printing, optimal results are usually obtained by printing in landscape orientation with minimal margins and a small text font.

Additionally, a user may import this report file into spreadsheet software such as Microsoft Excel to facilitate printing. Such spreadsheet software also may facilitate sorting and further manipulation of the data.
