ABSTRACT: Many inventions, great and small, are discovered independently at roughly the same time by two or more individuals or organizations. Famous examples include the light bulb (Edison and Swan), the telephone (Bell and Gray), and the integrated circuit (Kilby and Noyce). Such independent invention is common for minor technological improvements. How should property rights to an invention be defined and awarded in such cases? Patent law has struggled with this question for many years. The basic rule in the U.S. is that the patent is awarded to the first firm to invent; later independent inventors come up empty-handed. However, this basic system can create some peculiar results. Suppose that Firm A achieves an invention and files for a patent. Slightly later, but before the invention is made public, Firm B independently discovers the same invention. Firm A receives the patent and can even prevent Firm B from practicing its own invention. In legal terms, a party accused of patent infringement cannot defend itself by showing that it discovered the same invention independently. Would such an independent invention defense be desirable? Alternatively, suppose that Firm A achieves an invention, but decides not to file for a patent, perhaps because Firm A does not believe this invention is sufficiently novel and non-obvious to be patentable. Instead, Firm A uses the invention internally in its own operations as a trade secret. Later, Firm B independently discovers the same invention and files for a patent. Under current U.S. patent law, Firm B is awarded the patent because Firm A kept its invention secret.
