At the time of the filing, it would have been obvious to one of ordinary skill in the art to have replaced one(s) of the filters in Takeuchi (e.g., 13B) with the filter of Schmalzl. The modification would have been obvious because of substitution of similar filter (MPEP 2143(B) and as taught by Schmalzl (Col. 5 lines 45-47, Col. 6 lines 31-37). 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. Claim(s) 31-41, 50 is/are rejected under 35 U.S.C. 103 as being unpatentable over Takeuchi US 10,547,288 in view of Schmalzl US 10,840,887. 31.
