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 . Applicant has amended the claims resulting in new grounds of rejection under section 112. 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 7 depends from claim 1 Claim 1 recites step ii) hydrothermal treatment in a range of 75ºC to 400ºC while claim 7 recites 25ºC as the bottom of the range attempting thereby to broaden the range and rendering the claimed range indefinite. Similarly claim 1 recites the pressure range of 2 to 25 bar while claim 7 recites 1 bar again attempting to broaden the range and rendering the claimed range indefinite. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). Allowable Subject Matter Claims 1-6, 8-9 and 17-20 are allowed. The following is an examiner’s statement of reasons for allowance: the remarks filed 8/21/2026 are persuasive. The cited prior art does not teach the claimed method steps in the order as claimed working on the claimed combination of materials. The prior art does not teach or fairly suggest the claimed method. 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 Response to Arguments The examiner notes that withdrawn claims will need to be canceled. Claim 10 is a product by process claim (i.e. a carbonated material of hydrated cement and aggregate). The allowable claims are not directed to a product. There is no information on the unique or distinguishing properties of the product of claim 1; the product appears to be rendered obvious by previously cited prior art. The examiner notes that claims 11 and 12 do not set forth additional steps and do not further limit claim 1 as such they would be subject to rejection under section 112. Etc. 37 CFR 1.144 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.
