U.S. Supreme Court
Ryan v. Hard, 145 U.S. 241 (1892)
Ryan v. Hard
Argued April 28, 1892
Decided May 16, 1892
145 U.S. 241
Letters patent No. 241,321, granted May 10, 1881, to Charles A. Dunks and James B. Ryan, for improvements in swing woven-wire bed-bottoms, are invalid for want of patentability, all that was done being to suspend a fabric well known as a bed-bottom in substantially the same manner that other fabrics used for that purpose had been suspended.
The case is stated in the opinion. chanroblesvirtualawlibrary
