(a)Correction.— Whenever through error a person is named in an issued patent as the inventor, or through error an inventor is not named in an issued patent, the Director may, on application of all the parties and assignees, with proof of the facts and such other requirements as may be imposed, issue a certificate correcting such error.
(b)Patent Valid if Error Corrected.— The error of omitting inventors or naming persons who are not inventors shall not invalidate the patent in which such error occurred if it can be corrected as provided in this section. The court before which such matter is called in question may order correction of the patent on notice and hearing of all parties concerned and the Director shall issue a certificate accordingly.
(July 19, 1952, ch. 950, 66 Stat. 810; Pub. L. 97–247, § 6(b), Aug. 27, 1982, 96 Stat. 320; Pub. L. 106–113, div. B, § 1000(a)(9) [title IV, § 4732(a)(10)(A)], Nov. 29, 1999, 113 Stat. 1536, 1501A–582; Pub. L. 107–273, div. C, title III, § 13206(b)(1)(B), Nov. 2, 2002, 116 Stat. 1906; Pub. L. 112–29, § 20(f), Sept. 16, 2011, 125 Stat. 334.)
Historical and Revision Notes
This section is new and is companion to section 116.
The first two paragraphs provide for the correction of the inadvertent joining or nonjoining of a person as a joint inventor. The third paragraph provides that a patent shall not be invalid for such cause, and also provides that a court may order correction of a patent; the two sentences of this paragraph are independent.
