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 . Election/Restrictions This application is in condition for allowance except for the presence of claims 2, 12, 21-22 directed to an invention non-elected with traverse in the reply filed on 6/13/2023 (and are mutually exclusive with the allowed claims and therefore unable to be rejoined; claim 2 would bring about a 112 4th issue since it appears to not add anything to claim 1 that isn’t already present as elevations and depressions would have to be demarcated since they are structural risings and fallings). Applicant is given TWO (2) MONTHS from the date of this letter to cancel the noted claims or take other appropriate action (37 CFR 1.144). Failure to take action during this period will be treated as authorization to cancel the noted claims by Examiner’s Amendment and pass the case to issue. Extensions of time under 37 CFR 1.136(a) will not be permitted since this application will be passed to issue. The prosecution of this case is closed except for consideration of the above matter. Claims 1, 16-18, 20, 23 are allowable. The restriction requirement between species, as set forth in the Office action mailed on 3/23/2023, has been reconsidered in view of the allowability of claims to the elected invention pursuant to MPEP § 821.04(a). The restriction requirement is hereby withdrawn as to any claim that requires all the limitations of an allowable claim. Specifically, the restriction requirement of 3/23/2023 is partially withdrawn. Claims 3-4, 7-9, 11, 13, 15, directed to a species no longer withdrawn from consideration because the claims requires all the limitations of an allowable claim. However, claims 2, 12, 21, 22, directed to a species withdrawn from consideration because they have structure that is mutually exclusive from the claims that they depend (see above for further explanation). In view of the above noted withdrawal of the restriction requirement, applicant is advised that if any claim presented in a divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application. Once a restriction requirement is withdrawn, the provisions of 35 U.S.C. 121 are no longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01. Allowable Subject Matter Claims 1, 3-4, 7-9, 11, 13, 15-18, 20, 23 are allowed. The following is an examiner’s statement of reasons for allowance: The closest prior art of Holand and Arai show similar layer construction, but lack the specific makeup of each layer as now claimed and how the various characteristics vary from layer to layer and across the middle layer therebetween. 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.” 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.
