Decided April 27, 1942

CERTIORARI TO THE CIRCUIT COURT OF APPEALS

FOR THE SECOND CIRCUIT

Syllabus

l. It is the claim, not the specifications, that measure the grant of a patent. P. 145.

2. A disclaimer under the Patent Law, R.S. § 4917, which attempts to add new elements to a claim and thereby changes the character of the claim, is invalid, even though in other respects it narrows the claim. P. 147.

122 F.2d 292 affirmed.

Certiorari, 314 U.S. 604, to review the affirmance of a judgment dismissing a suit for infringement of a patent.
