§ 256. Correction of Named Inventor

     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 and such error arose without any deceptive intention on his part, the Director may, on application of all the parties and assignees, with proof of the facts and such other requirements as may be imposed, issued a certificate correcting such error.

     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.)

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.

Amendments

     1999—Pub. L. 106–113 substituted "Director" for "Commissioner" in two places.

     1982—Pub. L. 97–247 substituted "Correction of named inventor" for "Misjoinder of inventor" as section catchline and, in text, substituted "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 and such error arose without any deceptive intention on his part, the Commissioner 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" for "Whenever a patent is issued on the application of persons as joint inventors and it appears that one of such persons was not in fact a joint inventor, and that he was included as a joint inventor by error and without any deceptive intention, the Commissioner 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 deleting the name of the erroneously joined person from the patent", substituted "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" for "Whenever a patent is issued and it appears that a person was a joint inventor, but was omitted by error and without deceptive intention on his part, the Commissioner 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 adding his name to the patent as a joint inventor", and struck out provision that the misjoinder or nonjoinder of joint inventors not invalidate a patent, if such error could be corrected as provided in this section.
