(a) The word "applicant" when used in this title refers to the inventor or all of the joint inventors, or to the person applying for a patent as provided in §§ 1.43 , 1.45 , or 1.46 .

(b) If a person is applying for a patent as provided in § 1.46 , the word "applicant" refers to the assignee, the person to whom the inventor is under an obligation to assign the invention, or the person who otherwise shows sufficient proprietary interest in the matter, who is applying for a patent under § 1.46 and not the inventor.
