Office Action

§112
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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. Response to Arguments Applicant’s arguments, see pages 7-11 of Remarks, filed 03/05/2026, with respect to claims 1-14 have been fully considered and are persuasive. The rejection under 35 U.S.C. 103 of claims 1-14 has been withdrawn. 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 2 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. 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). In the present instance, claim 2 recites the broad recitation “a regular 2n-gon”, and the claim also recites “n=3 being selected” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Claim 13 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. 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). In the present instance, claim 13 recites the broad recitation “a semiconductor light source”, and the claim also recites “in particular a laser or LED light source” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Allowable Subject Matter Claims 1, 3-12, and 14-17 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 1, the prior art of record, taken either alone or in combination, fails to disclose or render obvious an optical measuring cell for absorption spectroscopic determination of at least one chemical and/or physical parameter of a fluid, the optical measuring cell comprising, among other essential features, deflecting elements connected to the cover and the base, the deflecting elements reflecting an incident light beam running substantially in parallel to the optical main axis laterally offset into the interior of the housing substantially in parallel to the optical main axis, wherein n (n>1) deflecting elements designed as roof prisms are connected to the cover and/or to the base such that they are arranged on each second side of a regular 2n-gon, and wherein the coupling-in element and/or the coupling-out element has/have an optical element connected to a roof prism of the roof prisms. Claims 3-12 and 14-17 are allowed by dependency. Claims 2 and 13 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) set forth in this Office action.
