Appeal No. 96-2404
Application No. 08/112,446
examiner and contrary to the appellants’ argument, the UK
reference explicitly discloses a rotary device in Figure 7
(also see lines 107 through 122 on page 2) which forms a
groove that is shaped like a ring. From our perspective, this
disclosure of the UK reference satisfies the claim 15
requirement of a rotary cutter used to form a ring-like
groove. With respect to claim 16 which requires use of a
punching tool as well as a rotary cutter for forming the first
and second recesses, it is significant in our view that the UK
reference teaches forming recesses with rotary devices as
explained above and with punching tools (e.g., see Figure 1
and lines 38 through 50 on page 2). While the UK reference
does not expressly teach using the punching and rotary devices
in combination for forming first and second recesses
respectively, one with ordinary skill in the art would have
found it obvious to use these devices in combination so as to
thereby form a respective recess via the more advantageous
tool. Thus, for example, it would have been obvious to use
the punching device of the UK reference as a more advantageous
tool for forming a first recess and to use the rotary device
