The Director shall cause an examination to be made of the application and the alleged new invention; and if on such examination it appears that the applicant is entitled to a patent under the law, the Director shall issue a patent therefor.
35 U.S. Code § 131 - Examination of application
Based on Title 35, U.S.C., 1946 ed., § 36 (R.S. 4893).
The first part is revised in language and amplified. The phrase “and that the invention is sufficiently useful and important” is omitted as unnecessary, the requirements for patentability being stated in sections 101, 102 and 103.
