PNG media_image3.png 445 434 media_image3.png Greyscale Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Iwabuchi in view of Sato WO 2020174705 A1. Re claim 11, Sato teach A thermal management system, comprising: a compressor (7); a first heat exchanger; a second heat exchanger (50, 60); a third heat exchanger (110); a throttling component 10). Sato fail to explicitly teach valve details. Iwabuchi teach and the fluid management apparatus according to claim 1 (see the rejection of claim 1), wherein the fluid management apparatus comprises a first connecting port, a second connecting port, a third connecting port, a fourth connecting port, a fifth connecting port, a sixth connecting port, a seventh connecting port and an eighth connecting port (noting 5 valves with an inlet and outlet which make at least ten ports in fig 7), an outlet of the compressor is in communication with the first connecting port, an inlet of the compressor is in communication with the eighth connecting port, the second connecting port and the third connecting port are in communication with a refrigerant flow passage of the first heat exchanger, respectively, wherein a refrigerant flow passage of the second heat exchanger is in communication with the fourth connecting port and the fifth connecting port, respectively, and the sixth connecting port is in communication with the seventh connecting port through the throttling component and the third heat exchanger (in the instant combination the fluid management apparatus according to claim 1 modifies 20 of the primary reference) to provide integrated plates with multiple valves. It would have been obvious to one of ordinary skill in the art at the time the invention was made to include valve details as taught by Iwabuchi in the Sato invention in order to advantageously allow for advanced process refrigerant flow controls and gas flow rates. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20170029679 A1, US 20240384808 A1.
