Patent Drafting: The Best Mode Requirement

US4652259_FigWhen describing an invention in a patent application, every inventor must disclose the best mode of carrying out the invention, known to the inventor. This requirement is found at 35 USC 112(a).  Therefore if the inventor knows of multiple ways of making or using the invention, he/she must not withhold the best way known to him or her while disclosing one or more inferior ways. That is the inventor must not withhold disclosure of his/her preferred mode.

Courts have described the best mode requirement as one ensuring that the patent applicant plays ‘fair and square’ with the patent system. The requirement ensures a quid pro quo of disclosure exchanged for the patent grant. Amgen, Inc. v. Chugai Pharmaceutical Co., Ltd., 927 F.2d 1200, 1209-10 (Fed. Cir. 1991).
