Historical and Revision Notes

May 23, 1930, ch. 312, § 1 46 Stat. 376 Based on Title 35, U.S.C., 1946 ed., § 40 (R.S. 4884, amended , ).

The reference to plants is omitted for inclusion in another section and the reference to the title is shortened since the title is of no legal significance.

The wording of the granting clause is changed to “the right to exclude others from making, using, or selling”, following language used by the Supreme Court, to render the meaning clearer.

“United States” is defined in section 100.
