    Cooperative Patent Classification (CPC)

    The Cooperative Patent Classification system replaced the ECLA system in 2013.  By 2015, the USPC is also expected to be completely replaced by the CPC in an effort by the USPTO and the EPO to harmonize patent classification systems.

    CPC is based on the European system called ECLA which itself was based on WIPO's IPC class structure.  The chief difference between IPC and CPC is CPC is far more detailed, but they are both based on the same high-level structure.

    Patents are classified with CPC codes as either "Inventive" classes or "Additional" classes (formerly called Non-Inventive).  In AcclaimIP, you can query patents by Inventive, Additional or both using different field codes as shown below.

    Inventive classes are displayed in Bold text in the expander rows in the search result grid and in the document details window.

    European Classification Field (ECLA)

    To search using the European Classification system which is usually just called ECLA, use the ECLA field code.

    Note:  ECLA has been deprecated in favor of the newer Cooperative Patent Classification (CPC) system.  New EP documents are no longer published with ECLA Codes.  Use the CPC field code instead!

    Field of Search Field (FOS)

    To search the classifications that the examiner searched and may or may not have listed in the patent classification field, use the FOS field code. FOS searches only US Classifications in granted US patents.

    US Applications do not contain any data in their FOS field.

  • To query patents by their primary US classification and include all children classes in a single query, use the PSCLS field code.  The PSCLS give you fine-tuned control over your class queries.
