  • In-bound citations are called forward citations.  Forward citing documents are almost always newer than the documents they cite.  

    Out-bound citations are called reverse citations.  Reverse cited documents are almost always older than the citing document.

    You can search for documents that cite a document or a set of documents.  You can further refine this query for searching for only examiner citations--that is the citations that were provided by an examiner in a patentabilty arguement, which are in contrast to those citations provided by the applicant in the form of an IDS.

    You can also search for documents by the number of citations they have accrued.  Notice some of the field codes end in _CT, which stands for "count."  The examples below show you how you can search for patents with a minimum number of total citations, or examiner citations.

    The field codes are consistently named, and if you remember FCITE and RCITE, and the two modifiers EX (for examiner), and _CT (for count), you can easily remember all 8 field codes for querying citation data.

    Cited Documents (RCITE)

    To query documents by the number of reverse citations, use the ANA_REFCITE_CT field.

    Reverse citations are older documents that a patent cites. Reverse citations are published along with the issued patent, and they do not change or increment as time goes on.  In other words, the reverse citations remain fixed during the life of the patent.

    Priority Count Field (ANA_PRIOR_CT)

    To query patents by the number of priority documents, use the ANA_PRIOR_CT field.

    Number of Claims Field (ANA_CLM_CT)

    To query patents by the total number of claims, use the ANA_CLM_CT field.

    Claim count is a value indicator especially since new rules whet into effect requiring additional examination fees if a patent contains more than 20 total claims and/or 3 independent claims.  Here is an interesting (although a little outdated) article on the topic:

    http://patentlyo.com/patent/2007/08/patents-with-mo.html

    By contrast to the 2007 data in the Patentlyo article, of the 5820 utility patents granted on 02/18/2014, only 9.9 percent had more than 25 claims--a drop of almost 50%!

    Number of Assignees Field (ANA_AS_CT)

    To query patents by the number of unique assignees in the original assignee (applicant) field, use the ANA_AS_CT field code.

    The ANA_AS_CT is especially useful when you want to find patents that are co-assigned or those that were collaborated on with another entity.

    Inventor Count Field (ANA_INV_CT)

    To query patents by the number of inventors named on the patent, use the ANA_INV_CT field code.

    The ANA_INV_CT field can be a value indicator.  Important patents may involve more inventors than the average patent.  The field is an integer field, and as a result, it is often used in a range query.

    Family Size Field (ANA_SFAM_CT)

    If you want to query patents by the size of the patent family, use the ANA_SFAM_CT field code.

    Family size is an important value indicator in patent data. Large families represent a large financial investment in patenting. We use the DOCDB "simple family" definition when we develop patent families. This means that all members share the same priority date. The simple family contains foreign counterparts, continuations and divisionals. The simple family will contain CIPs only if they have the same priority date as the rest of the family

    The ANA_SFAM_CT field holds integer numbers, and it is often useful to query the field using range queries.

    Simple Family Field (SFAM)

    If you want to find all the members of a patent's simple family, use the SFAM field code.

    The SFMA field code returns a list of patent documents in the patents simple family.

    AcclaimIP uses the DOCDB "simple family" definition when we develop patent families.  This means that all members share the same priority date.  The simple family contains foreign counterparts, continuations and divisionals.  The simple family contains CIPs (Continuation in Part) only if they have the same priority date as the rest of the family.

    The ANA_SFAM_CT field holds integer numbers, and it is often useful to query the field using range queries.

  • If you are searching for patent documents with particular legal event codes associated with them, you can use the LGL_CODE field code.

    Searching legal codes may not be for the beginner.  Each patenting jurisdiction (country) determines their own legal codes, so they are only useful when you search within one jurisdiction's patents.

    For a complete list of codes, refer the the link on the EPO's website:

    Image Count (IMAGE_COUNT)

    Use the IMAGE_COUNT field code to query patent by the number of pages of figures they have.  Images are added the same day that patents and applications are published.
