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.

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 Here is an interesting (although a little outdated) article on the topic: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.

Legal Event Count (ANA_LGL_CT) Field Code
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.

US Patent Reference, Number Only Field (REFN)
*This field code is now deprecated. Use FCITE which replaces both REFN and FREFN. FCITE returns both US and international citing documents in one query. FCITE has a reverse counterpart, RCITE which also queries both US and international reverse (backward) references.
To query patents that cite a particular patent number use the REFN field code.
REFN is useful to see who cites your portfolio when you use it to query a collection of patents
