What is the utility requirement in patent law?
The utility requirement in patent law refers to the necessity for an invention to have a specific and substantial credible utility. This requirement is established by 35 U.S.C. 101 and 35 U.S.C. 112(a) (or pre-AIA 35 U.S.C. 112, first paragraph). The Manual of Patent Examining Procedure (MPEP) provides guidelines for examining applications for compliance with this requirement.
According to the MPEP, “These Guidelines have been promulgated to assist Office personnel in their review of applications for compliance with the utility requirement. The Guidelines do not alter the substantive requirements of 35 U.S.C. 101 and 35 U.S.C. 112, nor are they designed to obviate the examiner’s review of applications for compliance with all other statutory requirements for patentability.”
In essence, the utility requirement ensures that patented inventions are useful and serve a practical purpose.
