U.S. Circuit Court for the Northern District of Illnois April 12, 1898 (Thrall v. Poole)

SHOWALTER, Circuit Judge

(after stating the facts). Defendants’ counsel do not seem to me to seriously contest the validity of the patent in suit. They insist that the patentee has so far limited his monopoly by the words of his claims that their client does not infringe.

By striking out the word “metal” and the word “flexible,” the claims appear as presented by the patentee in the patent office.
