Overview
Case summary
This case involves a patent infringement suit over U.S. Patent No. 322,366, issued to Samuel Fulton for a mattress with a rabbeted circumference that allows the lower portion to sink below bed rails, reducing overall bed height. The plaintiffs, assignees of the patent, sued the defendants for infringement. The defendants challenged the patent's validity based on prior art and public use, and denied infringement. The court found that the invention was made in 1881, antedating the prior art references, which were in different fields (car seats) and did not anticipate the mattress invention. The public use defense was not properly pleaded or proven. The court held the patent valid and found that the defendants' mattresses, with rabbeted sides supporting a low-suspended mattress, infringed the patent pro tanto. A decree was entered for the plaintiffs.
Abstract
Plaintiffs, assignees of a patent for a mattress with rabbeted circumference allowing the lower portion to sink below bed rails, sued defendants for infringement. Defendants challenged validity based on prior art from different fields and public use, but the court found the invention antedated the prior art, which did not anticipate it, and the public use defense was not properly pleaded or proven. The court held the patent valid and found defendants' similar low-suspended mattresses infringed it pro tanto, entering decree for plaintiffs.

- Defendants alleged to infringe the patent
- Defendants challenged patent validity based on prior art and public use
Disputed questions
- Whether patent was novel and patentable

Procedural history
3 steps- Suit filed for patent infringement
- Defendants answered asserting patent invalidity and denying infringement
- Court heard evidence and arguments
Evidence in the record
- Testimony of witnesses Smith and Weber showing invention made in 1881
- Patent No. 322,366 specification and claims
- File wrapper and contents showing examiner rejections and allowance
- Prior patents: No. 189,104 (Jones), No. 251,630 (Palmer), No. 237,586 (Palmer), No. 271,062 (Hale), No. 246,378 (Elston)
- Extensive use of the invention by defendants and others under licenses
- Evidence type: Prior patents (e.g., Elston, Hale) · Challenge basis: Anticipation and lack of patentable novelty · Trial court ruling: excluded · Reasoning: Patents are in different fields (car seats) and do not show the mattress invention; invention antedates them · Challenged on appeal: false · Appellate outcome: not applicable
- Evidence type: Public use by Judson and Holt · Challenge basis: Public use for more than two years prior to application · Trial court ruling: excluded · Reasoning: Defense not set up in answer and not clearly shown for two full years · Challenged on appeal: false · Appellate outcome: not applicable

“The invention is clearly and satisfactorily shown by the testimony of the witnesses Smith and Weber to have been made in 1881, before August 20.”WHEELER, District Judge — Discussing priority of invention over prior artEstablishes that the invention predates cited prior art, supporting validity
“Neither of the patents which antedate this invention comes anywhere near showing or describing it.”WHEELER, District Judge — Evaluating prior art referencesHighlights lack of anticipation by prior art, reinforcing patent novelty
“But the rabbeted sides support the low-suspended mattress all the way round, although they do not go across the ends, in the same way that the rabbeted parts of the patented structure do; and so they infringe pro tanto, at least.”WHEELER, District Judge — Analyzing infringementShows court's flexible interpretation of 'circumference' in claim, finding infringement despite differences
