    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.

    Priority Date Field (PRIRD)

    The priority date of a patent application can be searched using the PRIRD field code.  A patent's priority date can be as late as the filing date or  many years prior to the patent's file date.  Patents receive earlier priority dates for many reasons.

    • There was an earlier provisional application filed.
    • It is a child application from a previously filed PCT application.
    • It is a continuation (or CIP) from a parent application.
    • It is a divisional of a parent application.

    Searching priority dates within a range query is particularly useful when searching for prior art.

    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."

    Issue/Publication Date Field (ISD)

    When a patent document is published the publication date is stored in the issue date field which uses the field code ISD.  ISD is aliased to the field code PD (publication date). If it is easier to remember, use PD.  

    There are two different names for the same field because when you think of granted patents, you normally think in terms of its "issue date."  On the other hand, when you think of published applications, you normally think of its "publication date."  In either case, the data is stored in the same field in AcclaimIP's database and PD or ISD will query it.

    As with all other field codes, ISD can be used in conjunction with any number of field codes to develop complex queries.

    TAC Field Code (Title, Abstract, Claims)

    The TAC field code is used when you want to search for keywords and terms in any of the Title, Abstract or Claims fields. In other words, TAC eliminates searching the SPEC (specification) field and any of the ancillary fields found in the "default field set."

    TAC:(torque NEAR2 limiting) -->  is the same query as

    TTL:(torque NEAR2 limiting) OR ABST:(torque NEAR2 limiting) OR ACLM:(torque NEAR2 limiting)

    Title Field (TTL)

    The patent Title can be searched using the TTL field code.

    The examples below can be used in conjunction with any number of other field codes to construct complex queries.
