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.
Examples
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.
