Egbert v. Lippmann
Egbert v. Lippmann, 104 U.S. 333 (1881), was a case in which the Supreme Court of the United States held that public use of an invention bars the patenting of it. The Court's ruling was colored by its view that the inventor had forfeited his right to patent the invention by "sleeping on his rights" while others commercialized the technology.
Samuel Barnes designed "corset-steels", which were vertically disposed springs to stiffen a corset. Samuel made the invention in 1855 after he had been present while two women, his "intimate friend," Frances Willis, and her friend, Miss Cugier, were "complaining of the breaking of their corset steels." Samuel devised a stronger device using two pieces of metal fastened together to create a doubled, reinforced corset steel. He then gave the springs to Frances, who would in 1863 become his wife and later the executrix of his will. In 1858 he gave her another set of steels, which she used for a long time. In 1863, Samuel and Frances showed the invention to his friend Joseph Sturgis; and in March 1866 Samuel applied for a patent. Samuel died a month after the patent issued in July 1866. Frances remarried in 1870 and became Frances Egbert. Subsequently, Frances, as Samuel's executrix and owner of the patent, sued for patent infringement.
Frances Egbert sued Phillip Lippmann and August Seligmann in the Southern District of New York. Circuit Judge Blatchford tried the case and held the patent invalid because of public use. He ruled:
It was not a use for experiment, or a use in private or a private use. It was a practical use in public of the completed article [despite its concealment and invisibility within the corset]. No secrecy was maintained or enjoined as to the article or its structure.
Frances appealed the judgment to the Supreme Court.
Justice William Burnham Woods wrote for the majority, explaining that public use of the invention by only one person is sufficient to be considered a public use, even where the usage of the invention is not visible to the general public. Similarly, a gift to another party without regard to secrecy or restrictions on use is sufficient to bar a patent for the same reason. Whether the use of an invention is public use or private use "does not necessarily depend on the number of persons to whom its use is known."
Rather: "If an inventor, having made his device, gives or sells it to another, to be used by the donee or vendee without limitation or restriction or injunction of secrecy and it is so used, such use is public even though the use and knowledge of the use may be confined to one person." It is a public use because "[s}he might have exhibited them to any person, or made other steels of the same kind and used or sold them without violating any condition or restriction imposed on her by the inventor." Thus, the Court treated Barnes's gift of the corset steels to his "intimate friend" (not then his wife) without her first signing a confidentiality agreement as if it were a sale in the ordinary course of business.
The majority held that the use here was different from that in City of Elizabeth v. Pavement Company because this was not a good faith effort to test or experiment with the design. Furthermore, Barnes "slept on his rights" for the eleven years between 1855 and 1866, not applying for a patent until other manufacturers had already incorporated aspects similar to Barnes' design into their own products. He did not bother applying for a patent until he came to the belated realization that he could potentially profit from his invention. Thefore, the court held the patent invalid.
