Appeal No. 1999-1718
Application 08/786,742
Notwithstanding the foregoing deficiency in Williams, the
examiner has concluded that
it would have been obvious to one having ordinary
skill in the art at the time the invention was made
. . . to provide a distance of between 3 and 10
inches between the forward reaches of the [Williams]
disks, since it has been held that where the general
conditions of a claim are disclosed in the prior
art, discovering the optimum or workable ranges
involves only routine skill in the art. In re
Aller, 105 USPQ 233 [answer, page 4].
