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 . 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, 7, and 8 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 and 15 of U.S. Patent No. 12,284,021 (hereinafter ‘021). Although the claims at issue are not identical, they are not patentably distinct from each other. With respect to claim 1, patent ‘021 (claim 1) recites a solid constituent characterization method (utilizing the system), comprising: transmitting a transmit signal from a transmit antenna into a solid sample, the transmit signal is in a radio or microwave frequency range of the electromagnetic spectrum (lines 5-10); detecting a response at a receive antenna that results from transmission of the transmit signal to or into the solid sample (lines 11-15); and characterizing the solid sample based on the detected response (lines 21-23). With respect to claim 7, patent ‘021 (claim 1) recites the solid constituent characterization method of claim 1, wherein detecting the response comprises one or more electromagnetic response signals (lines 21-23). With respect to claim 8, patent ‘021 (claim 1) recites the solid constituent characterization method of claim 7, wherein characterizing the solid sample comprises comparing the one or more electromagnetic response signals with a stored reference signal (threshold; claim 15). 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. Claims 1-4 and 7-10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bosua et al. (US Publication 2022/0077918; hereinafter Bosua). With respect to claim 1, Bosua discloses a solid constituent characterization method (FIG. 6), comprising: transmitting a transmit signal from a transmit antenna (11; FIG. 1) into a solid sample (“medium”), the transmit signal is in a radio or microwave frequency range of the electromagnetic spectrum (74; [0106]; FIG. 6); detecting a response at a receive antenna (13; FIG. 1) that results from transmission of the transmit signal to or into the solid sample (76; [0106]); and characterizing the solid sample based on the detected response (78; [0106]). With respect to claim 2, Bosua discloses the solid constituent characterization method of claim 1, wherein the solid sample includes one or more constituents within a solid material ([0051]). With respect to claim 3, Bosua discloses the solid constituent characterization method of claim 1, wherein the solid sample is a homogenous solid material or a heterogeneous solid material ([0051]). With respect to claim 4, Bosua discloses the solid constituent characterization method of claim 1, wherein the solid sample comprises a metallic alloy, a concrete material, or a soil ([0051]).
