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. Claims 17 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Tamura in view of Kodama US 2018/0015747 A1 (hereinafter “Kodama”). Tamura teaches the claimed invention except for a "post-processing apparatus" (claim 17) or for "a relay apparatus" (claim 18) comprising the uneven roller. Kodama employs the uneven roller (FIG. 6) feeding sheets in a relay apparatus and post-processing apparatus (500 in FIG. 1) It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to employ Tamura's uneven roller arrangement in a the same setting as Kodama Uchida, for the predictable result of feeding sheets requiring relay and post-processing. Allowable Subject Matter Claims 11-12 and 16 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Response to Arguments Applicant’s arguments with respect to claims 1, 7, 19 and 20 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
