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 . This non-final Office action is in response to Applicant’s patent application number 18/986,780. Currently, claims 1-20 are pending and examined. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement (IDS) submitted on 12/19/2024 is being considered by the examiner. 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 1-20 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. Re claim 1, line 6; a phrase “which” renders the claim indefinite and confusing because it’s unclear whether “which” referring to which structure? Correction is required. Claims 2-20 depending upon the rejected claim 1 are also rejected. Claims 9, 10, 11, 20; having the same issue as mentioned are also rejected. Re claim 4, line 3; a conditional phrase “when” renders the claim indefinite and confusing because "when" is language that suggests or makes optional the subsequent limitation or limitations. Language that suggests or makes optional but does not require steps to be performed or does not limit a claim to a particular structure does not limit the scope of a claim or claim limitation. See § MPEP 2103 (C). Correction is required. Claims 6, 15, 17; having the same issue as mentioned are also rejected. Allowable Subject Matter Claims 1-20 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. The following is an examiner’s statement of reasons for allowance: no prior art discloses combination structures of a substrate processing apparatus, including the substrate is immersed in the phosphoric acid aqueous solution in the inner tub, and the circuitry controls a supply flow rate Q of the pure water based on a detection value H2_det of the liquid level H2 as set forth in the claims. 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 The prior art made of record and not relied upon is considered pertinent to applicant's disclosure (see attached PTO-892).
