Smith v. Hall, 301 U.S. 216 (1937)
Smith v. Hall
Argued October 20, 21, 1936
Reargued April 5, 6, 1937
Decided April 26, 1937
301 U.S. 216
1. Two suits in which different defendants, charged as infringers, set up the same ground of invalidity against a patent, and which were tried by the court below on a joint record, may be presented to this Court jointly. P. 301 U. S. 218.
3. Oral evidence held insufficient, in itself, to establish prior use of a patented method, but corroborated sufficiently by documentary evidence. P. 301 U. S. 222.
4. Anticipation of a patented method is shown by knowledge of the method, and its use with operative success, although without full and precise knowledge of the scientific principles involved, as outlined in the patent. P. 301 U. S. 226.
5. While, in attacking a patent, a Patent Office file on an abandoned application may not be relied on as a prior publication, it may be competent and cogent evidence of the nature and date of an earlier invention reduced to practice. P. 301 U. S. 227.
6. The Smith patent was sustained in the Snow and Waxham cases, supra, only by establishing that neither the arrangement of the eggs nor the particular order in which the propelled air current should reach the eggs, nor the manner in which it was guided or controlled, is part of the patent claimed. P. 301 U. S. 231.
7. A patentee who has sought and obtained a broad construction of his claim cannot narrow it so as to avoid anticipation by showing that the claimed method was used in a particular form of structure not claimed. P. 301 U. S. 232.
8. In determining anticipation of a patented method, it is immaterial that the structure employed in the earlier use was neither the best possible nor as skilfully designed or used as that later employed by the patentee. P. 301 U. S. 232. chanroblesvirtualawlibrary
9. Commercial success is not a necessary element of a prior use anticipating and invalidating a patent. P. 301 U. S. 233.
83 F.2d 217, 221, affirmed.
Certiorari, 298 U.S. 652, to review two decrees of the court below holding a patent invalid upon the ground of anticipation, and thereupon reversing decisions of two district courts which had held the patent valid and infringed. No. 35 was brought by Smith in Connecticut for alleged infringement of Claim 1 against defendants operating a large commercial hatchery in that State. No. 36 was a like suit by him in New York against a corporation engaged in the business of manufacturing and selling incubators and a commercial hatcheries company which it controlled.
