Brown v. Guild, 90 U.S. 181, 1874 WL 17361 (Mem), 23 L.Ed. 161, 23 Wall. 181

Facts

G. W. Brown filed two bills in equity against Bergen and Sisson, and against Selby and others, alleging infringement of his patents for improvements in corn-planting machines. The defendants claimed that Brown was not the original inventor and that his patents were fraudulently obtained. After extensive testimony, the Circuit Court dismissed Brown's bills, leading to appeals. The controversy centered on the validity of Brown's patents and whether the defendants' machines infringed upon them.

G. W. Brown filed two separate bills in equity in the court below, against Bergen and Sisson, in the one case, and against Selby and others in the other case, charging them respectively with infringement of certain letters-patent granted to him, Brown, for improvements in corn-planting machines, being reissues of previous patents, and praying for an account of profits, for injunctions, and for general relief.

Issue

Whether G. W. Brown was the original and first inventor of the improvements claimed in his patents, and whether the defendants infringed those patents.

Rule

A patent must demonstrate novelty and non-obviousness to be valid. The burden of proof lies with the complainant to establish that they are the original inventor and that their invention is not anticipated by prior art. Additionally, claims in a patent must clearly distinguish what is new from what is old.

Analysis

The court analyzed the evidence presented by both parties regarding prior inventions and the specific claims made by Brown in his patents. The defendants provided evidence of prior machines that they argued anticipated Brown's inventions. The court found that several of Brown's reissued patents lacked patentable novelty and that the defendants' machines did not infringe upon the valid claims of Brown's patents.
