Bessen/Hunt Technique - Details

Details

The technique proposed by Bessen and Hunt involves conducting a keyword search within the USPTO patent database as follows:

(("software" in specification) OR ("computer" AND "program" in specification))

AND (utility patent excluding reissues)

ANDNOT ("chip" OR "semiconductor" OR "bus" OR "circuit" OR "circuitry" in title)

ANDNOT ("antigen" OR "antigenic" OR "chromatography" in specification)

An actual query that may be submitted to the USPTO database to retrieve patents granted in 2005 is as follows:

ISD/(1/1/2005->1/1/2006)

AND SPEC/(software OR (computer AND program))

AND APT/1

ANDNOT TTL/(chip OR semiconductor OR bus OR circuit OR circuitry)

ANDNOT SPEC/(antigen or antigenic OR chromatography)
