Appeal No. 1999-2225 Application No. 08/815,441 factors such as the nature of the invention, the predictability of the art, and the relative skill of persons in the art. For example, the examiner argues that the claimed invention is inoperative because an inlet or outlet is not disclosed in the specification. However, the examiner has not established that any undue experimentation would be involved in providing an operative canister for the claimed vacuum assembly. While the examiner would have us believe that any knowledge in the prior art needed to establish enablement must be recited in the specification (Examiner's answer, pages 3-4), this is not the law.

Cir. 1987)("A patent need not teach, and preferably omits, what is well known in the art."); Paperless Accounting, Inc. v. Bay Area Rapid Transit Sys. , 804 F.2d 659, 664, 231 USPQ 649, 653 (Fed. Cir. 1986)("A patent applicant need not include in the specification that which is already known to an available to the public."); Hybritech Inc. v.
