Appeal 2007-1275
Application 09/824,248
PRINCIPLES OF LAW
On appeal, all timely filed evidence and properly presented argument
is considered by the Board. See In re Piasecki, 745 F.2d 1468, 1472, 223
USPQ 785, 788 (Fed. Cir. 1984).
In the examination of a patent application, the Examiner bears the
initial burden of showing a prima facie case of unpatentability. Id. at 1472,
223 USPQ at 788. When that burden is met, the burden then shifts to the
applicant to rebut. Id.; see also In re Harris, 409 F.3d 1339, 1343-44, 74
USPQ2d 1951, 1954-55 (Fed. Cir. 2005) (finding rebuttal evidence
unpersuasive). If the applicant produces rebuttal evidence of adequate
weight, the prima facie case of unpatentability is dissipated. In re Piasecki,
745 F.2d at 1472, 223 USPQ at 788. Thereafter, patentability is determined
in view of the entire record. Id. However, on appeal to the Board it is an
appellant's burden to establish that the Examiner did not sustain the
necessary burden and to show that the Examiner erred -- on appeal we will
not start with a presumption that the Examiner is wrong.
"Section 103 forbids issuance of a patent when 'the differences
between the subject matter sought to be patented and the prior art are such
that the subject matter as a whole would have been obvious at the time the
invention was made to a person having ordinary skill in the art to which said
subject matter pertains.'" KSR Int'l Co. v. Teleflex Inc., 127 S. Ct. 1727,
1734, 82 USPQ2d 1385, 1391 (2007). The question of obviousness is
resolved on the basis of underlying factual determinations including (1) the
scope and content of the prior art, (2) any differences between the claimed
subject matter and the prior art, and (3) the level of skill in the art. Graham
