Office Action

§102 §103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Allowable Subject Matter Claim s 5 , 6, and 11-18 are allowable over the prior art of record. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. 1. Claim s 1 -4 , 7 -9 , and 19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Rowley et al. ( US20180154754 ). 2 . Regarding claims 1-4 , 7-9 and 19, Rowley teaches a cooling box (see Figure below) , comprising: a chassis, wherein the chassis is provided with a first side wall, a bottom wall and a lower accommodation cavity surrounded by the first side wall and the bottom wall; and a cooling assembly, arranged in the lower accommodation cavity, wherein the cooling assembly comprises a lower flow-channel plate and an upper flow-channel plate, the upper flow-channel plate is sealingly connected to the chassis, a sealed accommodation space is formed between the upper flow-channel plate and the chassis, the lower flow-channel plate is arranged in the accommodation space, and a flow-channel space is formed between the upper flow-channel plate and the lower flow-channel plate (see Figure below) . 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 of this title, 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. 3. Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable Rowley et al. ( US20180154754 ) in view of Wang ( US20200161721 ). 4 . Regarding claim 10 , the complete discussion of Rowley as applied to claim s 1, 7 is incorporated herein. However, they are silent about the limitations of claim 10 . 5. Wang teaches an upper cover (lid structure 150 [0032], Figure 1) , wherein the upper cover has an upper accommodation cavity (lid structure 150 can include a module current collector 155… The module current collector 155 can house or include a set of conductive lines [0033]) , the upper cover (lid structure 150 [0032], Figure 1) , is sealingly connected to the chassis (chassis 110, Figure 1) , a mounting space (space between 150 and 110, Figure 1) is formed by the upper accommodation cavity and the lower accommodation cavity, and the mounting space is configured to accommodate a battery module (battery modules 145, Figure 1) for the benefit of improvement in integrity of the battery pack by lowering a risk of fluid leakage [0002] 6 . It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have modified Rowley with Wang’s teachings for the benefit of improvement in integrity of the battery pack by lowering a risk of fluid leakage .
