Office Action

§102
DETAILED ACTION 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 . 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. Claim(s) 1-7 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CN 205941990 U to WU, Xue-dong (Wu). In Reference to Claim 1 Wu discloses: PNG media_image1.png 462 784 media_image1.png Greyscale A heat-insulated interface arrangement for an exhaust gas aftertreatment device (6), comprising: a first electric interface (optical fiber); an inner sheath (3) which ensheathes the first electric interface (optical fiber); and a heat-insulating sheath 4 which ensheathes the inner sheath (5) such that the heat-insulating sheath 4 circumferentially surrounds an outer circumferential surface of the inner sheath (3), wherein the heat-insulating sheath (4) has a ceramic material or is formed from a ceramic material. In Reference to Claim 2 Wu discloses: wherein the heat-insulating sheath (4) is frictionally connected to the inner sheath 3. In Reference to Claim 3 Wu discloses: an outer sheath (505) which ensheathes the heat-insulating sheath (4). In Reference to Claim 4 Wu discloses: wherein the outer sheath (505) is frictionally connected to the heat-insulating sheath (4). In Reference to Claim 5 Wu discloses: wherein the inner sheath (5) and/or an outer sheath (505) which ensheathes the heat-insulating sheath (4) has a metallic material or is formed from a metallic material. In Reference to Claim 6 [AltContent: textbox (A)]Wu discloses: [AltContent: connector][AltContent: arrow] PNG media_image2.png 443 675 media_image2.png Greyscale A heat-insulated interface arrangement for an exhaust gas aftertreatment device (6), comprising: a first electric interface (optical fiber); a heat-insulating sheath (4) which ensheathes the first electric interface (optical fiber), wherein the heat-insulating sheath (4) is formed by a gap (A) that circumferentially surrounds an outer circumferential surface of the first electric interface (optical fiber) and that is disposed between the outer circumferential surface of the first electric interface (optical fiber) and an outer sheath (505) ensheathing the heat- insulating sheath (7); and an intermediate element (101) which is disposed on the first electric interface (optical fiber), wherein the intermediate element (101) is adjacent to the heat- insulating sheath 4 and is ensheathed by the outer sheath (505). In Reference to Claim 7 Wu discloses: wherein: the intermediate element (21) is ring shaped; or the intermediate element (21) has at least two intermediate sub-elements (25). Reasons for Allowance The following is a statement of reasons for the indication of allowable subject matter: Claims 9-14 are allowed primarily because the prior art of record cannot anticipate Applicant’s claimed invention by a single reference nor render Applicant’s claimed invention obvious by the combination of more than one reference. Furthermore, the prior art of record does not teach “an exhaust gas aftertreatment housing (4) which has a wall (2), wherein an exhaust gas is flowable through the exhaust gas aftertreatment housing (4); a first electrical conduit (31.1); an electrical feedthrough (27) which passes the first electrical conduit (31.1) through the wall (2) of the exhaust gas aftertreatment housing (4); and a heat-insulated interface arrangement (1), wherein the heat-insulated interface arrangement (1) is disposed outside the exhaust gas aftertreatment housing (4) on the first electrical conduit (31.1) and is connected to the first electrical conduit (31.1) in an electrically conductive manner;” as within the context of the claimed invention as disclosed and within the context of the other limitations present in claim 9 and 10; Therefore, the prior art of record cannot anticipate Applicant’s claimed invention by a single reference nor render Applicant’s claimed invention obvious by the combination of more than one reference. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Response to Arguments Applicant’s arguments with respect to claim(s) 1-7 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. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
