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 8-10 are rejected under 35 U.S.C. 103 as being unpatentable over Krehmer et al. (US-20180209478) in view of Kanamaru et al et al. (US-20210010561). Regarding claims 8-10, Krehmer et al. discloses the use of a rigid polymer for the material of the at least one auxiliary member, but is silent as to a specific rigid polymer. Regarding claim 8, Kanamaru et al. teaches wherein a retention feature formed of a thermoset polymeric material ([0059] at least wherein nylon is a thermoplastic). Regarding claim 9, Kanamaru et al. teaches wherein a thermoset polymeric material comprising one or more of aliphatic polyamides ([0059]). Regarding claim 10, Kanamaru et al. teaches wherein the thermoset polymeric material comprising one or more of aromatic polyamides, aromatic polyimides, and aliphatic polyimides ([0059]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use a polymeric material with vibration damping characteristics as taught by Kanamaru et al. to achieve a desired result based on the engineering design. Claims 17 is rejected under 35 U.S.C. 103 as being unpatentable over Krehmer et al. (US-20180209478) in view of Fitzgerald (US-7735812). Regarding claim 17, Krehmer et al. discloses the use of a metal for the material of the mount but is silent as to iron or steel. Fitzgerald teaches wherein steel (col. 4, lines 18-45) is the metal used for a material of an engine mount. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use iron or steel as taught by Fitzgerald to achieve a desired result based on the engineering design. Allowable Subject Matter Claim 16 is 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 filed 2/11/2026 have been fully considered but they are not persuasive. Regarding claims 1 and 18, Applicant argues that the prior art of record Krehmer lacks wherein “the retention feature includes a first portion and a second portion, the first portion comprising openings or the second portion comprising grooves”, Examiner respectfully disagrees. As set forth above, it has been interpreted that the retention feature 5a/5b in at least figure 5 includes a first portion (fig 5, 10a or 10b) and a second portion (11a-d), the spaces 9a-d in 10a and 10b, open towards 4, and between elements 11a and 11b, or 11c and 11d have been interpreted as openings. With regards to the “or” clause and under a different interpretation, the spaces 9a-d between elements 11a and 11b or 11c and 11d have been interpreted as grooves. Applicant also argues that the prior art of record Kanamaru lacks wherein a retention feature is “tunable to provide a selected precompression of the vibration mitigation element and a selected rate for the vibration mitigation element” Examiner respectfully disagrees. In [0017]-[0020] Kanamaru describes limiting the displacement and deformation of a movable part and the mount holding part 20 (retention feature). It has been interpreted that the ability to limit the displacement and deformation of the movable part and the mount holding part 20 reads over being tunable to provide a selected precompression and selected rate. The selection has been interpreted as the appropriate limit that has been set. With regards to the amendment, as set forth above Kanamaru discloses wherein the retention feature includes a first portion (20/51) and a second portion (22), the first portion comprising openings (fig 1, at least 21a) or the second portion comprising grooves (fig 1, at least grooves on 22a). Regarding claims 1 and 18, it appears that the arguments are more specific than the limitation set by the claims. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
