Brief Fact Summary. Fisher (Plaintiff) stated that his claimed invention, relating to five purified nucleic acid sequences (genes), also known as expressed sequence tags (ESTs), that encoded proteins and protein fragments in maize plants, had a specific and substantial utility and that his patent application made it possible for someone of ordinary skill in the art to use the invention.
Synopsis of Rule of Law. A patent application that reveals general generic uses of a claimed invention, which simply assists research, lacks utility and lacks enablement.
Issue. Does a patent application that reveals general generic uses of a claimed invention, which simply assists research, lack utility and lack enablement?
Held. (Michel, C.J.)Â Yes.Â A patent application that reveals general generic uses of a claimed invention, which are simply assist research, lacks utility and lacks enablement.Â Plaintiff’s argument that the claimed ESTs provide seven specific and substantial uses, regardless of whether the functions of the genes corresponding to the claimed ESTs are known is not convincing.Â Basically, the claimed ESTs do no more than assist in research that may help scientists to isolate the particular underlying protein-encoding genes and conduct further experimentation on those genes.Â The overall goal of such experimentation is presumed to understand the maize genome.Â Therefore, the claimed ESTs are only “objects of use-testing,” meaning scientific research could be performed on the objects with no assurance that anything useful will be discovered in the end.Â Plaintiff’s comparison of the ESTs to a patentable microscope is also not convincing.Â A microscope can immediately reveal an object’s structure, but the claimed ESTs can only be used to detect the presence of genetic material which has the same structure as the EST itself.Â It is not able to provide any information about the overall structure let alone the function of the underlying gene.Â So while a microscope can give an immediate, real-world benefit in a variety of applications, the claimed ESTs cannot.Â The claimed ESTs themselves are not an end of Plaintiff’s research effort, but only tools to be used along the way while searching for a practical utility.Â Plaintiff’s claimed ESTs may add a noteworthy contribution to biotechnology research, but their utility is not sufficient to be eligible for patent because Plaintiff does not identify the function for the underlying protein-encoding genes.Â Without sufficient identification, the claimed ESTs do not deserve a patent as they have not been researched and understood to the point of providing an immediate, well-defined, real world benefit to the public.Â Plaintiff’s claimed uses are not sufficient to meet the standard for a “substantial” utility under Â§ 101.Â The claimed inventions also lack enablement under Â§ 112.Â Affirmed.
Necessarily, compliance with § 112 requires a description of how to use a presently useful invention, otherwise an applicant would anomalously be required to teach how to use a useless invention.View Full Point of Law
Discussion. Even though a research tool may not provide immediate benefit to the public at large, Judge Radar points out, and other scholars agree, that the incremental benefit offered to researchers should count as utility that deserves patent protection.Â As it stands, the utility benefit is narrowly applied.
