Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 14 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Connors in view of official notice. Regarding claims 14 and 20. Connors does not disclose that the assembly is located in the interior of a housing. However, the use of heat pipe assemblies inside of electronic housings to improve heat dissipation from the heat generating electronic components is old and well known in the art and would have been obvious to one of ordinary skill in the art. Claims 14 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Tong in view of official notice. Regarding claims 14 and 20.
