Appeal 2006-2351
Application 10/645,493
finishing element to prevent scratches (i.e., unwanted surface damage) on
the glass.
Furthermore, Molnar I discloses that lubricants should be provided to
the fluid in the interface between the workpiece surface being finished and
the finishing element finishing surface in an amount of 0.1 to 15% by weight
of the total fluid between the interface (Molnar I, col. 28, ll. 5-15). Molnar I
further discloses independently controlling the amount of lubricant such that
the lubricant may be supplied to the interface from either the slurry or from
the finishing element (Molnar I, col. 28, l. 50 to col. 29, l. 11). Horie
discloses that the amount of lubricant is such that it is “effective for
preventing formation of scratches on glass” (Horie, col. 3, ll. 56-62).
Therefore, Molnar I and Horie recognize that the amount of lubricant
necessary to achieve proper lubrication at the interface so as prevent damage
to the workpiece is a result-effective variable such that it would have been
obvious for an artisan with ordinary skill to develop workable or even
optimum ranges for such art-recognized, result-effective parameters. In re
Woodruff, 919 F.2d 1575, 1578, 16 USPQ2d 1934, 1936-37 (Fed. Cir.
1990); In re Boesch, 617 F.2d 272, 276, 205 USPQ 215, 219 (CCPA 1980);
In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955).
For the foregoing reasons, we affirm the Examiner’s § 103(a)
rejection of argued claim 24 and non-argued claims 25-26 over Molnar I in
view of Horie.
