Overview
Case summary
This case involves a suit in equity by National Folding Box & Paper Company against Stecher Lithographic Company for alleged infringement of letters patent No. 259,416, granted in 1882 to the Munsons for improvements in manufacturing paper boxes. The patent describes an apparatus with a die and counter-die for cutting and creasing box blanks. Defendants argued lack of novelty and invention, and non-infringement. The court narrowed the issue to whether providing grooves in the counter-die to co-operate with embossing rules for creasing fold lines involves invention. After reviewing prior art, including the Shelton patent (1870) and Snow patent (1872), which showed similar methods for creasing fold lines in paper articles like boxes and collars, the court held that the Munson patent added no novel mechanism or principle, and any improvements were obvious to skilled artisans. The patent was declared void for want of invention, and the bill was dismissed.
Abstract
Plaintiff sued in equity for infringement of a patent on an apparatus using a die and counter-die for cutting and creasing paper box blanks. Defendants contested novelty, invention, and infringement, with the court focusing on whether grooves in the counter-die for creasing fold lines constituted invention. After examining prior art showing similar creasing methods, the court held the patent added no novel mechanism or principle and was obvious, declaring it void and dismissing the bill.
Opinion of the court
opinionCOXE, District Judge
- The patent lacks novelty and invention.
- Prior art, including Shelton and Snow patents, anticipates the Munson patent.
- Improvements are due to natural evolution of the art and would be obvious to skilled artisans.
- No infringement as patent is invalid.

Facts & evidence
Key facts
8 facts- Complainant owns letters patent No. 259,416 granted to Edward B. and Harvey S. Munson on June 13, 1882 for improvements in the manufacture of paper boxes.
- The patent describes an apparatus with a die and counter-die for cutting out blanks for paper boxes and defining lines of ultimate foldings.
- The die has cutting and embossing rules; the counter-die has channels corresponding to embossing rules to crease the fold line.
- Defendants are charged with infringing this patent since 1894.
- Defenses include lack of novelty and invention, and non-infringement.
- The controversy narrows to whether providing channels or grooves in the counter-die to co-operate with embossing rules involves invention.
- Prior art includes the Shelton patent (October 1870) and Snow patent (1872) showing similar methods for creasing fold lines in paper articles.
- The art of making paper boxes with creases along fold lines and embossing on paper was old before the Munson patent.
Disputed questions
- Whether the Munson patent involves invention over prior art.
- Whether defendants' apparatus infringes the patent.

“If there be anything in the patent limiting the claims to a particular variety of packing or fastening the court has not been able to discover it.
