that each entire slide member can be readily removed and
replaced."
After the scope and content of the prior art are
determined, the differences between the prior art and the
claims at issue are to be ascertained. Graham v. John Deere
Co., 383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966).
Based on our analysis and review of Telesio and claim 12,
it is our opinion that the only difference is the limitation
that each slide member is attached to the ejector mechanism by
removable attaching means such that each entire slide member
can be readily removed and replaced.
With regard to this difference, the examiner determined
(answer, p. 3) that it would have been obvious to "have
removably attached the slide members [Telesio's guide shoes
64] to the ejector mechanism [Telesio's packer plate 20] by
reusable attaching means to facilitate disassembly as taught
by Herpich." We agree.
