Appeal 2007-3874
Application 10/288,027
Claim 7 illustrates Appellant’s invention of a net-shaped molded heat
sink, and is representative of the claims on appeal:1
7. A net-shaped molded heat sink for dissipating heat away from a
heat generating object with a contact surface, said heat sink comprising:
a core plate of carbon-carbon matrix material having an outer surface;
a thermally conductive main body having a top surface and a bottom
interface surface and being molded of a thermoplastic polymer composition
having a base polymer matrix and a thermally conductive filler material
uniformly distributed throughout said base polymer matrix; the thermally
conductive main body being positioned about the core plate of carbon-
carbon matrix material thereby completely surrounding the outer surface of
core plate [sic], a portion of the thermally conductive main body being an
interface layer including the bottom interface surface, wherein the bottom
interface surface of the interface layer is in thermal communication with the
contact surface fo [sic] the heat generating object; and
a plurality of thermally conductive fins integrally connected to and
emanating from said top surface and being made of a polymer composition
molded with thermally conductive filler material interdispersed therein.
The Examiner relies upon the evidence in these references:
Ruechardt US 3,564,109 Feb. 16, 1971
Ross US 5,572,070 Nov. 5, 1996
Unger US 5,834,337 Nov. 10, 1998
Mahulikar US 5,939,214 Aug. 17, 1999
Appellant requests review of the grounds of rejection of claims 7 and
8 advanced on appeal (Br. 3-4): under 35 U.S.C. § 112, first paragraph, as
failing to comply with the written description requirement (Answer 3); and
under 35 U.S.C. § 103(a) as unpatentable over Mahulikar in view of Unger,
further in view of Ruechardt and Ross (id.).
1 We reproduce claim 7 as it stands of record as of the Amendment filed
July 26, 2004, in view of the errors in the claim as presented in the Claim
Appendix to the Brief. Br. 12.
