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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 03/05/2026 has been entered. Status of Claims Claims 1, 4, 6, 8, and 9 are currently amended, Claims 2, 3, and 10 are as previously presented, Claims 5 and 7 are as originally filed, Claims 11-20 are withdrawn, and Claims 21 and 22 are new. 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 4-9 are 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 4 recites the limitation "the entire portion" in lines 2 and 3. There is insufficient antecedent basis for this limitation in the claim. The entire portion” should be “the first portion” since the “entire portion” includes “a first portion and a second portion” in Claim 1, lines 3 and 4. see [0014, 0047-48, 0053]. Claim 6 recites the limitation "the entire portion" in line 2. There is insufficient antecedent basis for this limitation in the claim. The entire portion” should be “the first portion” since the “entire portion” includes “a first portion and a second portion” in Claim 1, lines 3 and 4. see [0014, 0047-48, 0053]. Claim 8 recites the limitation "the entire portion" in lines 2 and 3. There is insufficient antecedent basis for this limitation in the claim. The entire portion” should be “the first portion” since the “entire portion” includes “a first portion and a second portion” in Claim 1, lines 3 and 4. see [0014, 0047-48, 0053]. The heat treatment assembly cannot be configured and dimensioned to be simultaneous if the entire portion is heated to a sub-solvus temperature and the second portion, which is part of the first portion, is heated to a super-solvus temperature. Claim 9 recites the limitation "the entire portion" in line 3. There is insufficient antecedent basis for this limitation in the claim. The entire portion” should be “the first portion” since the “entire portion” includes “a first portion and a second portion” in Claim 1, lines 3 and 4. see [0014, 0047-48, 0053]. The heat treatment assembly cannot be configured and dimensioned to be simultaneous if the entire portion is heated to a super-solvus temperature and the second portion, which is part of the first portion, is heated to a sub-solvus temperature. Claims dependent on any of the rejected claims are likewise rejected under this statute. Allowable Subject Matter Claims 1-3, 10, 21, and 22 are allowed. Claims 4-9 would be allowable if rewritten 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 and to include all the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: JP S57-94524, cited in the previous office action, teaches a heating device for continuous annealing but does not suggest the furnace is configured to heat an entire portion of the metal component as claimed.
