    Document Type Field (DT)

    The DT field code divides your search into patents and applications.  There are two acceptable values for the DT field code:

    • G -->  Grants (granted patents)
    • A -->  Applications

    Note that Document Type (DT) field code works on all international patents.  By contrast, the Patent Type field (PT) works only on US documents.

    Patent Type Field (PT)

    The PT field code is one that you should commit to memory.  It lets you filter and query for different type of patents.  There are five acceptable values for the PT field code:

    • U -->  Utility Patents
    • D -->  Design Patents
    • PP  -->  Plant Patents
    • RE -->  Reissue Patent
    • H  -->  SIR (Statutory Invention Registration)

    Note that PT is different than KCOD (Kind Code) or DT (Document Type).

  • To query patents using an unnormalized "current" assignee, use the ANRE_CUR field code.

    Assignee names in AcclaimIP are normalized. There are often hundreds of name variations for a single assignee, and it would be virtually impossible to work with assignee information without normalization.

    However, from time to time, you may want to search the unnormalized current assignee name. Keep in mind, the current assignee comes from the "Reassignment database"

    Original Assignee Field (AN_ORIG)

    If you want to search on ONLY the original assignee name as printed on the document, you can use the AN_ORIG field code.

    Unlike the AN field code, AN_ORIG searches ONLY the original name as printed on the patent document. This field is NOT normalized and includes punctuation, misspellings, and crazy variants of all the assignee names.

    The field is useful for looking up specific misspellings of a name.

    Guessed Assignee Field (ANG)

    Patent documents often do not contain an assignee name.  Blank assignee names is more common in patent applications than granted patents.  AcclaimIP guesses the assignee for you.  We can guess names with a high degree of accuracy by analyzing inventor names, agent names, locations, dates and technology classes.

    AcclaimIP includes the guessed assignee name in a field code called ANG (Assignee Normalized Guessed).  Note that the ANG field contains both the guessed and the canonical (not guesses) assignee name from the ANC field.

    Also a name may change from a guessed variant to a canonical variant if an anonymous patent application is granted with an assignee name.  AcclaimIP will update the current assignee of the application with the official name.

    All Assignees Field (AN)

    AN is a special field code for searching all the assignee fields at once including the original, guessed, current, and chain of custody variants in their normalized and non-normalized states. While not precise (at all), it is often helpful for cleaning up lists and seeing if there are any outliers that our normalization team missed.

    Original Assignee Field (ANO)

    The original assignee is the name that appears on the document's official PDF.  The original assignee is usually the applicant, and may or may not be the current assignee of the patent.

    Unlike the Current Assignee, the Original Assignee name never changes in our data (except for normalization).

    The field code is ANO (Assignee Normalized Original).

    The ANO field is normalized to fix misspellings, unnecessary long variants of the entity name, and creative punctuation.

    Current Assignee Field (ANC)

    The current assignee is the entity who currently owns a patent or application.  It may be a different entity than the name that appears on the patent (this is the applicant, or in AcclaimIP parlance, the "Original Assignee").

    The field code is ANC (Assignee Normalized Current).

    The current assignee is different only if the new patentee registers the change of ownership with the USPTO which is currently not a requirement.  AcclaimIP processes the USPTO's assignment data weekly.

    Assignee Names are normalized to account for misspellings, creative punctuation and plain old variants of the same entity.

    MDATE and TRANCHE Field Codes

    The MDATE field code is one of the most powerful tools you have at your disposal.  It allows you to analyze abandonment and renewal behavior with precision.  Some of the uses for MDATE include:

    • Which patents are expired and in the public domain
    • Which patents can still be resurrected
    • Which patents are currently in their grace period?
    • What is the abandonment behavior of Company XYZ, in which classes, and how has it changed over time.
    • Predict to the penny future fees required to maintain a portfolio and when the payments will be due.

    To take advantage of the Power of MDATE, a little background is required.

    File Date Field (APD)

    A patents file date represents the day the completed application was filed at the patent office.  Use the field code APD to query the file date.  It is easy to remember if you think of "Application Date."
