Office Action

§102 §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 (i.e., changing from AIA to pre-AIA ) 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. 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 7 and 8 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. In regard to claim 7, the limitation “the magnifying lens” lacks antecedent basis. For examination purposes, it is presumed the limitation is “a magnifying lens”. In regard to claim 8, the limitation “the eyepiece lens” renders the scope of the claim unclear. Namely, it is unclear if the limitation is referring to the eyepiece housing of claim 1 or if a new element is being introduced in the claim. For examination purposes, it is presumed either will meet the limitation. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-20 are rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Kemper (US 2022/0341707 A1). In regard to claim 1, Kemper discloses a locking assembly 100 (denoted “diopter adjustment device”, see e.g. paragraph [0014] and Figure 2) comprising (see e.g. Figures 2-4): a scope tube 110 (denoted “diopter adjustment barrel”, see e.g. paragraph [0014] and Figure 2) including a first threading 120 (denoted “external threads”, see e.g. paragraph [0014] and Figure 3), wherein the first threading 120 comprises overlapping first rotating direction thread form 124 or 126 (denoted “left-handed external threads” and “right-handed external therads”) and second rotating direction thread form 126 or 124, and the second rotating direction thread form is opposite the first rotating direction thread form (see e.g. paragraph [0014] and note 124 and 126 are left handed and right handed rotating respectively); an eyepiece housing 130 (denoted “eyeshell”, see e.g. Figure 3 and paragraph [0014]) including a second threading 132 (denoted “internal threads”, see e.g. Figure 3 and paragraph [0014]) having the first rotating direction thread form (see e.g. paragraph [0014] where it is noted that the threads formed to engage with the first threading), wherein the second threading 132 is configured to engage with the first rotating direction thread form of the first threading (see e.g. paragraph [0014] where it is noted that the threads formed to engage with the first threading); and a binding nut 140 (denoted “stop nut”, see e.g. paragraph [0015] and Figure 3) including a third threading 144 (denoted “internal threads”, see e.g. paragraph [0015] and Figure 4) having the first rotating direction thread form (see e.g. paragraph [0015] where it is noted that 144 is set to engage with 120), wherein the third threading 144 is configured to engage with the second rotating direction thread form of the first threading (see e.g. paragraph [0015] where it is noted that 144 is set to engage with 120).
