In re Scarbrough, 500 F.2d 560, 182 U.S.P.Q. (BNA) 298 (C.C.P.A. 1974) (full-text).
Factual Background Edit
The application related to devices which provided vocal responses, under control of a computer, from a vocabulary of spoken words stored in analog form. Each device in the application was identified only by its generic name and the overall function it performed. The applicant claimed that with this identification, a person of ordinary skill would be able to make and use the apparatus with only a reasonable amount of experimentation.
