    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.

    Primary US Classification (PCCL)

    The primary US class appears first on the patent, it is in bold text, and it is supposed to best represent the "inventive step" of the invention.  To find patents that are classified by the primary class, use the PCCL field code.  The primary classification is in contrast to the cross-reference (XR) classification(s).

    You may hear the term "Original" or "OR" bantered around by patent examiners.  This is the USPTO's internal jargon for the primary class.  It is called Original because when an application is received by the USPTO the first action is to classify it (by the Classification Group--a contracted vendor).  The PTO uses this "original" class to route the patent to the proper examination art unit.

    Note: The CCL field code returns patents classified by either the Primary or the cross reference (XR) classes.

  • It is usually better and more inclusive if your class queries include children classes too.  To include children classes, use the SCLS field code rather than CCL.

    US patents are continuously reclassified by the USPTO.  As a result, the classes on the printed patent (PDF) may not match those in AcclaimIP's database.  AcclaimIP process the new classification file six times per year as it becomes available.

    Current US Class (CCL)

    To query patents by the US Class, use the CCL field code.

    Keep in mind that US classes evolve over time, and patents are continuously re-classified. So the classes printed on the printed patent (PDF) may not match the classes we have on record.

    The CCL query finds patents classified in the specified class by both Primary and Cross Reference classifications

    AcclaimIP processes the new classification file when it is released six times per year.

    Granted Patent Number Field (GPN)

    The GPN field helps you understand the status of applications.  When an application is granted, AcclaimIP inserts the granted patent number in the parent application's GPN field.  GPN works on all collections (countries).

    The GPN field answers the question.  "Which of my applications have granted, and if they have granted what is the patent number of the grant."

    You can also query the field directly.  GPN requires a patent number as the argument and returns an application in your result.

    Application Number Field (APN)

    To query the application serial number, use the APN field code.

    Please note that a US patent's application serial number is in the form 12/012345 and is the number assigned to the application shortly after it is received by the USPTO. Where 12 is the series code (containing one million applications) and the following six digits are the number that identifies the application. If you want to search the Application Publication Number, use the DN or PN field codes. Application publication numbers are in the form of US20100047408 A1, for example.

    APNs are not universally unique since a patent and its published application shares the same APN.

  • Patent and application numbers can be queried using the PN or DN field codes. PN (Patent Number) is an alias of the DN (Document Number) field. AcclaimIP uses two codes to query the same field to help users remember since patent number doesn't really apply to an application.

    Inventor Address Field (IADR)

    To search for a specific address of an inventor, use the IADR field. Inventor addresses are already parsed into City, State/Province, and Country fields with their own field codes. Therefore, the IADR field is most useful when searching for a specific street address of an inventor.
