Appeal No. 2006-1309 Application No. 09/166,625 Garland actually “has a thickness of 0.0005 - 0.002 inches or 0.5 - 2 mils” (page 11 of Answer, first paragraph). In response, appellant has not refuted the examiner’s calculations by pointing to any error therein but has simply offered a bald challenge to the calculations (see page 2 of Reply Brief, second paragraph). Accordingly, we will accept the examiner’s calculations as reasonable. Furthermore, it should be quite clear that a layer of a drop cloth cannot realistically have a thickness of 0.0005 mils, which is on the order of microns. In addition, it is well settled that where patentability is predicated upon a change in a condition of a prior art composition, such as a change in size, concentration or the like, the burden is on the applicant to establish with objective evidence that the change is critical, i.e., it leads to a new, unexpected result. In re Woodruff, 919 F.2d 1575, 1578, 16 USPQ2d 1934, 1936 (Fed. Cir. 1990); In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). In the present case, appellant has not attached any criticality to the claimed thickness, and the disclosed preference for the claimed thickness would seem to allay any suggestion of criticality (see page 10 of specification, second paragraph). -5-Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
