Appeal 2006-2238
Application 10/168,709
cross-linking (Br. 2-3). Independent claim 1 is illustrative of the invention
and is reproduced below:
1. A method for the production of a cross-linked support matrix in
form of a porous monolith or particles that packed to a
chromatographic bed will permit liquid flow velocities above 5 cm/h,
preferably above 50 cm/h, to pass through the bed for at least 1 hour,
comprising the steps of:
(a) providing a starting support matrix that has pendent unsaturated
groups, and
(b) subjecting said starting support matrix to electron beam or gamma-
ray irradiation to effect crosslinking.
The Examiner has relied on the following references as evidence of
unpatentability:
Berendee SU 1033181 Aug. 7, 1983
(published Russian Inventor’s Certificate)1
Park WO 96/03147 Feb. 8, 1996
(published International Patent Application)
Claims 1-2, 6-7, 9-10, 14-15, and 17-19 stand rejected under
35 U.S.C. § 102(b) as anticipated by Park (Answer 3). Claims 1-2, 4-6, 8,
10, 12-13, and 16 stand rejected under § 102(b) as anticipated by Berendee
(Answer 4). Claims 3 and 11 stand rejected under 35 U.S.C. § 103(a) as
unpatentable over Park (Answer 5). Based on the totality of the record, we
AFFIRM the rejections on appeal based on Park essentially for the reasons
1 We rely upon and cite from a full English translation of this document,
previously made of record. We note that Appellants and the Examiner
denominate this document as “Berendee” although the first named inventor
is “Zibarev” (Translation 1). For purposes of this appeal, we will refer to
this document as “Berendee.”
