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.


ANA_INV_CT:1 --> Finds patents with exactly one named inventor.

ANA_INV_CT:[5 to 10] --> Finds patents with from 5 to 10 inventors named on the patent.

ANA_INV_CT:[* to 5] --> Finds patents with five or fewer inventors' names on the patent.
