Appeal No. 1999-0421 Page 2
Application No. 08/587,866
BACKGROUND
The appellants' invention relates generally to heat sink structures having high-
performance cooling capabilities, more particularly to heat sinks having a large plurality of fin
structures which exhibit a large surface area per unit volume and, even more particularly, to
high-performance millifin heat sinks having improved structural rigidity, excellent thermal
transfer characteristics and ease of manufacture (specification, page 1). Further understanding
of the invention can be derived from a reading of exemplary claim 1, which appears in the
appendix to the appellants' brief.
The prior art references of record relied upon by the examiner in rejecting the appealed
claims are:
Minakami et al. (Minakami) 5,381,859 Jan. 17, 1995
Kashima S64-38593 Feb. 8, 19891
(Japanese published unexamined patent application)
The following rejection is before us for review.
Claims 1-4, 6-10, 12 and 13 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Minakami in view of Kashima.
Reference is made to the main and reply briefs (Paper Nos. 15 and 17) and the answer
(Paper No. 16) for the respective positions of the appellants and the examiner with regard to
the merits of this rejection.
1An English language translation of this reference, prepared by the Patent and Trademark Office, is
appended hereto.
