Office Action

§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. Claim 30 is 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. Regarding Claim 30, it is unclear how the adhesion promoter is to comprise both a Ni alloy and a CoCr alloy. Are at least two different regions to be characterized with one being Ni alloy and the other CoCr alloy? Is there some other meaning, such as a NiCoCr alloy? Response to Amendment In view of applicant’s amendments and arguments, applicant traverses the section 112, paragraph (b) rejection of the Office Action mailed on 17 June 2026. Rejection is withdrawn expect to the extent repeated above. Applicant’s Response has not addressed this aspect of the repeated rejection. In view of applicant’s amendments and arguments, applicant traverses the section 102 rejection over Endress, the section 102 rejection over Osumi, the section 103 rejection over Endress, the section 103 rejection over Yoshihiro, and the section 103 rejection over Osumi of the Office Action mailed on 17 June 2026. Rejections are withdrawn. Allowable Subject Matter Claim 30 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 16-23, 25, and 26 are allowed. Regarding Claims 16-23, 25, 26, and 30, the reviewed prior art does not teach or suggest the subject matter of these claims for the reasons of record. See Office Action mailed on 17 June 2026 (paragraph 28). 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.
