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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 31 December 2025 has been entered. 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 6 and 7 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 6 recites the limitation "wherein drying the hair comprises" in lines 1-2 There is insufficient antecedent basis for this limitation in the claim as claim 1 does not recite a step of drying the hair, but claim 1 does recite a step of “drying the section of hair” in line 31. For purposes of examination, Examiner will interpret claim 6 lines 1-2 as, and suggests amending to, “wherein drying the section of hair”. Claim 7 recites the limitation "wherein drying the hair comprises" in lines 1-2 There is insufficient antecedent basis for this limitation in the claim as claim 1 does not recite a step of drying the hair, but claim 1 does recite a step of “drying the section of hair” in line 31. For purposes of examination, Examiner will interpret claim 6 lines 1-2 as, and suggests amending to, “wherein drying the section of hair”.

Response to Arguments Applicant’s arguments, see p. 10, filed 31 December 2025, with respect to the rejection of claim 1 have been fully considered and are persuasive as the amendments overcome the prior art of record. The rejection of claim 1 and the rejection of dependent claims 3-10 and 21-22 has been withdrawn. Applicant's arguments filed 31 December 2025 regarding the rejection of claims 12 and 16 have been fully considered but they are not persuasive. Examiner notes that the Applicant’s arguments are narrower than the claim limitations as claims 12 and 16 are apparatus claims which do not recite the method of claim 1 and do not recite recognition of problems associated with lengthening curly or coily hair. In the above rejection, claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Rontal in view of Stewart and Botcher in view of Townsell, and claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Rontal in view of Botcher and Stewart in view of Townsell.
