Chemcast Corp. v. Arco Industries Corp. United States Court of Appeals, Federal Circuit

In a precedent-setting case that is widely cited in courts today, Reising helped the court create a novel and concise formulation of the best mode analysis as a two-part test. This two-part test continues to be cited today in U.S. courts.

The two-part best mode analysis that was formulated during this case:

  • Did the inventor have a best mode?
  • If the inventor had a best mode, did he disclose it in the patent application?

What makes this case stand out is the way Reising helped shape the law in a meaningful way, and how the firm ferreted out the facts that were decisive in evaluating the two-part test of the best mode analysis. Reising successfully defended Arco Industries.
