A research copy — for the controlling text, always check the official state or federal source. Not legal advice.

Whenever a claim of a patent is invalid, an action may be maintained for the infringement of a claim of the patent which may be valid. The patentee shall recover no costs unless a disclaimer of the invalid claim has been entered at the Patent and Trademark Office before the commencement of the suit.

(July 19, 1952, ch. 950, 66 Stat. 813; Pub. L. 93–596, § 1, Jan. 2, 1975, 88 Stat. 1949; Pub. L. 112–29, § 20(h), Sept. 16, 2011, 125 Stat. 334.)

Historical and Revision Notes

Based on Title 35, U.S.C., 1946 ed., § 71 (R.S. 4922).

The necessity for a disclaimer to recover on valid claims is eliminated. See section 253.
