Application No. 10/822,054
“cold plates”) may be thermally coupled to the electrical component to
absorb the heat from it (id. at ¶¶ 3 to 5).
“One aspect . . . of the invention relates to providing radial flow paths
in a cold plate. Another aspect . . . of the invention relates to providing an
impinging flow point near a relatively hotter spot of a heat source.” (Id. at ¶
20.)
Claims 1-20, all the pending claims, are finally rejected and on appeal
(Br. 1). The Examiner relies on the following prior art as evidence of
unpatentability:
Anderson U.S. Pat. 5,412,536 May 2, 1995
Doll U.S. Pat. 6,796,370 Sep. 28, 2004
Claims 1-20 stand rejected under 35 U.S.C. § 103(a) as obvious over
Doll in view of Anderson (Br. 2). Appellants separately argue the following
groupings of claims: 1) claims 1-3, 7-9, 13-15, 19, and 20 (Br. 3); 2) claims
4, 10, and 16 (Br. 5); 3) claims 5, 11, and 17 (Br. 6); and 4) claims 6, 12, and
18 (Br. 6). Within each grouping, the claims stand or fall together because
Appellants have not provided arguments for any individual claim. 37 C.F.R.
§ 41.37(c)(1)(vii). We select claims 1, 4, 5, and 6 as representative of each
grouping for the purpose of deciding this appeal. They read as follows:
1. An apparatus, comprising:
an enclosure having a fluid inlet and a fluid outlet in fluid
communication with the fluid inlet; and
a channel structure inside the enclosure between the inlet
and the outlet defining a plurality of radial flow paths,
wherein an impingement point for cooling fluid in the
enclosure is located at a position corresponding to an expected
relatively hotter spot of a heat source.
