Rule of Law:
A patent application does not satisfy the enablement requirement under 35 U.S.C. § 112 if it merely describes a theoretical concept and fails to provide a complete set of specific, operable parameters that would allow a person skilled in the art to make and use the invention without undue experimentation.
Facts:
- Gordon Gould filed a patent application for a 'Q-switched' laser on April 6, 1959.
- At the time of Gould's filing, no operable laser had ever been successfully constructed by anyone.
- Gould's application contained extensive theoretical discussions and suggested various materials and configurations for building a laser.
- A research company, TRG, Inc., where Gould was employed, received a nearly one-million-dollar government contract to build a laser based on Gould's disclosure.
- Between May 1959 and May 1960, TRG's well-funded effort to construct a laser based on Gould's application resulted in failure.
- In April 1960, Dr. Theodore Maiman of Hughes Aircraft Company, through independent research, successfully built the world's first operable laser using a pink ruby crystal.
- Robert Hellwarth, a coworker of Maiman, filed a patent application for a Q-switched laser on August 1, 1961, incorporating the now-proven working technology.
Procedural Posture:
- Gould and Hellwarth were parties in an interference proceeding before the Board of Patent Interferences to determine priority of invention for a 'Q-switched' laser.
- Both parties relied on their application filing dates, with Gould being the senior party and Hellwarth the junior party.
- Hellwarth filed a motion arguing that Gould's earlier patent application was insufficient to meet the legal disclosure requirements.
- The Board of Patent Interferences heard testimony from expert witnesses regarding the sufficiency of Gould's disclosure.
- The Board awarded priority of invention to Hellwarth, concluding that Gould's 1959 application did not contain an enabling disclosure.
- Gould (appellant) appealed the Board's decision to the U.S. Court of Customs and Patent Appeals, with Hellwarth as the appellee.

Issue:
Does a patent application that describes the theoretical principles for an invention, but does not provide a complete set of operating parameters for a working example, satisfy the enablement requirement of 35 U.S.C. § 112 at a time when no such device had ever been successfully built?
Opinions:
Majority - Lane, Judge.
No. A patent application fails to meet the enablement requirement of 35 U.S.C. § 112 if its disclosure is merely a fertile field for experimentation rather than a guide to a working invention. The court found that Gould's 1959 application, filed before any laser had been built, was insufficient to teach a person skilled in the art how to make an operable laser. The disclosure lacked a complete set of parameters for any specific laser, and expert testimony confirmed that significant experimentation was still required. The fact that a well-funded research team (TRG) failed to build a laser using Gould's proposal further evidenced that the disclosure was not enabling. The first successful laser was built by Maiman through his own extensive investigation, not by following Gould's application, reinforcing the conclusion that Gould's disclosure was a theoretical proposition rather than an enabled invention.
Analysis:
This case solidifies the principle that the enablement requirement is a significant hurdle for patents on pioneering or undeveloped technologies. It establishes that a patent cannot be granted for a mere research proposal or a scientific theory, no matter how prescient. The decision prevents inventors from claiming broad rights to a concept before they have conceived of a concrete, operable embodiment, thereby ensuring that patents reward tangible inventions rather than abstract ideas. This precedent requires that an application, especially in a new field, must provide a specific and reproducible blueprint, not just a collection of suggestions that requires extensive future experimentation to implement.
