Patent Exhaustion

Famous quotes containing the words patent and/or exhaustion:

    The cigar-box which the European calls a “lift” needs but to be compared with our elevators to be appreciated. The lift stops to reflect between floors. That is all right in a hearse, but not in elevators. The American elevator acts like the man’s patent purge—it works
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    The becoming of man is the history of the exhaustion of his possibilities.
    Susan Sontag (b. 1933)
