Cooperative Patent Classification (CPC) Combination Set Data Now Available in CAplus, INPADOC and USPAT Databases

14. October 2014

As of September 28, CPC combination set data can be searched in the following STN databases: CA/CAPLUS, INPADOCDB/INPAFAMDB, USPATFULL/ USPAT2/USPATOLD.

CPC combination sets are groups of CPC symbols linking multiple features of an invention. Patent examiners assign these combination sets in special technical fields to support more precise CPC searching. Major technical areas include polymeric mixtures, cement formulations and organic synthesis. CPC combination sets are fully available for the entire backfile in INPADOC, comprising more than 2,4 million applications.

Benefits of searching CPC Combination Sets include:

  • Unique access points. Many CPC codes are unique to CPC combination sets which have not been available before.
  • Precision. Searching multiple CPC codes in the same CPC combination set retrieves highly relevant answer sets.
  • Value for novelty searching. The patents retrieved from a search for multiple CPCs in a single combination set are likely to be of interest to those assessing the novelty of an invention.

More information on CPC combination sets, including search and display examples, is available at:
