Document:
the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.
the subject matter disclosed and the claimed invention, not later than the effective filing date of the claimed invention, were owned by the same person or subject to an obligation of assignment to the same person.
the application for patent for the claimed invention discloses or is amended to disclose the names of the parties to the joint research agreement.
if the patent or application for patent is entitled to claim a right of priority under section 119, 365(a), 365(b), 386(a), or 386(b), or to claim the benefit of an earlier filing date under section 120, 121, 365(c), or 386(c), based upon 1 or more prior filed applications for patent, as of the filing date of the earliest such application that describes the subject matter.
Paragraphs (a), (b), and (c) are based on Title 35, U.S.C., 1946 ed., § 31 (R.S. 4886, amended (1) Mar. 3, 1897, ch. 391, § 1, 29 Stat. 692, (2) May 23, 1930, ch. 312, § 1, 46 Stat. 376, (3) Aug. 5, 1939, ch. 450, § 1, 53 Stat. 1212).
No change is made in these paragraphs other than that due to division into lettered paragraphs. The interpretation by the courts of paragraph (a) as being more restricted than the actual language would suggest (for example, “known” has been held to mean “publicly known”) is recognized but no change in the language is made at this time. Paragraph (a) together with section 104 contains the substance of Title 35, U.S.C., 1946 ed., § 72 (R.S. 4923).
Paragraph (d) is based on Title 35, U.S.C., 1946 ed., § 32, first paragraph (R.S. 4887 (first paragraph), amended (1) Mar. 3, 1897, ch. 391, § 3, 29 Stat. 692, 693, (2) Mar. 3, 1903, ch. 1019, § 1, 32 Stat. 1225, 1226, (3) June 19, 1936, ch. 594, 49 Stat. 1529).
The section has been changed so that the prior foreign patent is not a bar unless it was granted before the filing of the application in the United States.
Paragraph (e) is new and enacts the rule of Milburn v. Davis-Bournonville, 270 U.S. 390, by reason of which a United States patent disclosing an invention dates from the date of filing the application for the purpose of anticipating a subsequent inventor.
Paragraph (f) indicates the necessity for the inventor as the party applying for patent. Subsequent sections permit certain persons to apply in place of the inventor under special circumstances.
Paragraph (g) is derived from Title 35, U.S.C., 1946 ed., § 69 (R.S. 4920, amended (1) Mar. 3, 1897, ch. 391, § 2, 29 Stat. 692, (2) Aug. 5, 1939, ch. 450, § 1, 53 Stat. 1212), the second defense recited in this section. This paragraph retains the present rules of law governing the determination of priority of invention.
Language relating specifically to designs is omitted for inclusion in subsequent sections.

L. 112–211 substituted “to claim a right of priority under section 119, 365(a), 365(b), 386(a), or 386(b), or to claim the benefit of an earlier filing date under section 120, 121, 365(c), or 386(c)” for “to claim a right of priority under section 119, 365(a), or 365(b), or to claim the benefit of an earlier filing date under section 120, 121, or 365(c)”.
