Office Action

§102 §103 §112
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 § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 8 and 18 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The phrase “the second extend direction” in claim 8 and “the second extent direction” in claim 18 lack proper antecedent basis in the claims. Claim Rejections - 35 USC § 102 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 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, 2, 4-7 and 14-17 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by DE-102015007523 (DE’523). Re: claim 1.

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. Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Baek in view of US Patent Application 2019/0353214 to Philpott et al. Baek includes a surface, as labeled, pointing in the second or upward extent of the holding groove, has a surface texture, but is silent with regards to the surface texture being a roughness that corresponds to or is greater than a minimum roughness, wherein the minimum roughness corresponds to an average roughness value of 0.8 micrometers. Philpott et al. teach in claim 6 the use of a brake anchor having a surface with a roughness that corresponds to or is greater than the average roughness value of 0.8 micrometers. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to have modified the surface of the holding groove of Baek to have had a roughness corresponding to or being greater than the average roughness value of 0.8 micrometers, in view of the teachings of Philpott et al., in order to provide a means of more securely holding the protruding part of the clip to help prevent unwanted decoupling of the guide element from the brake anchor thereby improving the stability and durability of braking. Response to Arguments Applicant's arguments filed 9/3/25 have been fully considered but they are not persuasive. Examiner notes that the explanation in response to the drawing objection has changed Examiner’s understanding of the claim language in claims 10 and 18. The claims have now been rejected based on the new understanding. A non-final office action has been issued as a result of the new rejections. With respect to the 112 rejections, Examiner has maintained the rejection of claim 18 since improper antecedent basis still exists in the claim as set forth above. With regard to the 102 rejections, Examiner has interpreted the second end of DE’523 to be in the new position set forth above, and the fixing portion, as labeled, is arranged at the newly labeled second end as shown. Examiner maintains that the fixing portion is a spring element to the extent that it forms a part of the return or restoring device 30 which is described and shown as being made of thin sheet metal that under force serves as an elastically deformable spring element. With regard to the 102 rejections using Baek, Examiner notes that the amendments necessitated the use of a new interpretation of the fixing portion of the Baek reference as set forth above.
