This was a patent infringement case in which the trial court first found the patent to be invalid because the design was being made and used two years before the patent application documents were filed. Justice Jackson wrote the opinion for the Supreme Court finding the patent invalid by the same reasoning as the trial court. Jackson emphasized key elements of the trial that he felt were over looked by the court of appeals in their decision.
