Overview
Case summary
This patent infringement case involved U.S. Patent No. 343,060 granted to S. E. Nutting for a map case designed to hold a single rolled map. The patent claimed a combination of a back piece, covering, and end pieces with the covering attached directly and extending over, in front of, and partially under the rolled map. Originally, the patent application claimed a self-closing feature using a round on the map's lower edge, but this claim was rejected by the Patent Office as anticipated by a prior patent for railway signals (Couch and Lamb, No. 181,912). Nutting acquiesced in the rejection and amended the claims. The trial court dismissed the infringement suit for want of equity. On appeal, the Circuit Court of Appeals affirmed, holding the patent void for lack of patentable invention. The court found the changes from prior map cases (holding a single map instead of several, portability, ornamental design) were matters of mechanical skill rather than inventive faculty. Additionally, the court held that after acquiescing in the rejection of the claim featuring the round, Nutting could not now construe the patent to include that feature. Even if invention were conceded, the patent would be so narrowly construed as to exclude infringement by the defendant's device.
Abstract
In this patent infringement suit over a map case design, the patentee originally claimed a self-closing feature using a round on the map's edge but acquiesced after rejection for anticipation by prior art, amending the claims to a combination of back piece, covering, and end pieces. The courts held the patent void for lack of invention, finding the changes from prior map cases—such as holding a single map, portability, and ornamental design—to be mere mechanical skill, and narrowly construed the claims to exclude the defendant's device even if invention were assumed. The dismissal for want of equity was affirmed on appeal.

Legal principles applied
- Invention requires more than change of form or juxtaposition of parts; must introduce new mode of operation or effect not before produced
- Commercial success alone does not establish invention absent doubt
