Office Action

§102 §DP
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 . Response to Amendment Receipt is acknowledged of the Preliminary Amendment filed on June 24, 2024. Accordingly, claims 1-8 and newly added claims 9-20 are currently pending in the application. Information Disclosure Statement The information disclosure statement (IDS) submitted on June 24, 2024 is being considered by the examiner. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of copending Application No. 18/722,588 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the reference application claims all that is claimed. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. It is noted that: The term “gradation of light” as recited in the claims is given its broadest reasonable interpretation, which is common and consistent with the interpretation that those skilled in the art would reach, as “light reception level”. The term “a camera” as recited in the appealed claims at issue was given its broadest reasonable interpretation, which is common and consistent with the interpretation that those skilled in the art would reach, as “light receiving element”. Claim Rejections - 35 USC § 102 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. 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. Claims 1-5 and 7-16 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Blanche (US 2020/0158855 A1). Blanche teaches a method for measuring a property possessed by an object comprising: PNG media_image1.png 524 930 media_image1.png Greyscale PNG media_image2.png 654 964 media_image2.png Greyscale With regard to claim 1, a propagation environment estimation method for estimating a propagation environment of a radio wave (electromagnetic (EM) waves in a radiofrequency (RF) range) using a scale model (FIG. 2A, target 210), the propagation environment estimation method comprising: creating a scale model (FIG. 2A, target 210); installing, in the scale model (FIG. 2A, target 210), a light source (FIG. 2A, laser source 220) regarded as a transmission station of a radio wave (electromagnetic (EM) waves in a radiofrequency (RF) range); irradiating (FIG. 2A, light beam 240) a measurement range in the scale model (FIG. 2A, target 210) by the light source (FIG. 2A, laser source 220); capturing (FIG. 11, camera 1120) the measurement range irradiated by the light source (FIG. 2A, laser source 220); and calibrating (using scaled-reduction factor N) gradation of light (FIG. 2A, 2D image 260 of the target 210) obtained by the capture for converting (using scale reduction factor N) it into a reception level (signal intensity) of the radio wave (electromagnetic (EM) waves in a radiofrequency (RF) range) (For more details, please read: Abstract; paragraphs: [0006]-[0008], [0026]-[0037], [0042]-[0045], [0063]-[0068], [0077]-[0080]; and claim 1).
