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)

Famous quotes containing the word details:

    Then he told the news media
    the strange details of his death
    and they hammered him up in the marketplace
    and sold him and sold him and sold him.
    My death the same.
    Anne Sexton (1928–1974)

    Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.
    Willard Van Orman Quine (b. 1908)

    If my sons are to become the kind of men our daughters would be pleased to live among, attention to domestic details is critical. The hostilities that arise over housework...are crushing the daughters of my generation....Change takes time, but men’s continued obliviousness to home responsibilities is causing women everywhere to expire of trivialities.
    Mary Kay Blakely (20th century)
