Patent Misuse - Statutory Limitation

Statutory Limitation

The scope of the patent misuse doctrine is today limited by 35 U.S.C. § 271(d):

“ No patent owner otherwise entitled to relief for infringement or contributory infringement of a patent shall be denied relief or deemed guilty of misuse or illegal extension of the patent right by reason of his having done one or more of the following:
(1) derived revenue from acts which if performed by another without his consent would constitute contributory infringement of the patent;
(2) licensed or authorized another to perform acts which if performed without his consent would constitute contributory infringement of the patent;
(3) sought to enforce his patent rights against infringement or contributory infringement;
(4) refused to license or use any rights to the patent; or
(5) conditioned the license of any rights to the patent or the sale of the patented product on the acquisition of a license to rights in another patent or purchase of a separate product, unless, in view of the circumstances, the patent owner has market power in the relevant market for the patent or patented product on which the license or sale is conditioned.

Famous quotes containing the word limitation:

    “...to many a mother’s heart has come the disappointment of a loss of power, a limitation of influence when early manhood takes the boy from the home, or when even before that time, in school, or where he touches the great world and begins to be bewildered with its controversies, trade and economics and politics make their imprint even while his lips are dewy with his mother’s kiss.”
    —J. Ellen Foster (1840–1910)
