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 . 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 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. Status of Claims Below is the Final Action on the Merits for claim 31. Claims 1 – 30 and 32 are allowed. Claim Objections Claims 1 and 31 are objected to because of the following informalities: Claims 1 and 31 recite “a blowing function” in lines 8 respectively and should recite “the blowing function”. Appropriate correction is required. 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 31 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. Claim 31 recites the limitation “a bottom” in line 13. The limitation is vague in that it is unclear as to what exactly is being claimed. A bottom of what? For the purpose of examination the limitation will be examined as a bottom of a first stationary vane. Claim 31 recites the limitation “a top” in line 24. The limitation is vague in that it is unclear as to what exactly is being claimed. A top of what? For the purpose of examination the limitation will be examined as a top of a first stationary vane. Allowable Subject Matter Claim 31 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. Response to Arguments Applicant’s arguments, see Applicants Arguments/Remarks dated April 30, 2026 with respect to the rejection of claims 1 – 30 have been fully considered and are persuasive. Claims 21 and 26 where objected as being allowable subject matter in the Non-Final Office action dated 01/30/2026. Applicant has rewritten claims 21 and 26 in independent form, thus claims 1 – 30 and 32 are allowed. 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.
