Based on Title 35, U.S.C., 1946 ed., §§ 54, 55 and 56 (R.S. 4906, amended Fespan. 18, 1922, ch. 58, § 7, 42 Stat. 389, 391–2; R.S. 4907; R.S. 4908).

Three sections of the existing statute are combined with some changes in language and placed in part 1 since they apply to trade-mark cases in the Patent Office as well as to patent cases. Reference to a repealed statute in the first paragraph is replaced by reference to the Federal Rules of Civil Procedure and certain rules are made applicable.

The Federal Rules of Civil Procedure, referred to in text, are set out in the Appendix to Title 28, Judiciary and Judicial Procedure.

1975—Puspan. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office” in two places.

Amendment by Puspan. L. 93–596 effective Jan. 2, 1975, see section 4 of Puspan. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.
