Office Action

§102 §103 §DP
Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. The preliminary amendment filed 5/10/2024 has been entered. Claims 21-38 are pending. Claims 21-38 stand rejected. 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. Claim 21 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 10,615,851 in view of Monogioudis et al. (Pub. No.: US 20100009717 A1), hereafter referred to as Monogioudis. Although the claims at issue are not identical, they are not patentably distinct from each other because both conflicting claims recite A method of transmitting a data stream to a mobile terminal in a communications network including a plurality of transmitting sites, comprising: designating at least two of the plurality of transmitting sites as cooperating sites, each cooperating site comprising at least two antennas; receiving a precoder report from the mobile terminal for each cooperating site wherein the precoder report is selected from a precoder set; and at each cooperating site, transmitting the data stream to the mobile terminal using a beam formed by the cooperating site's antennas. Claim 1 of U.S. Patent No. 10,615,851 fails to clearly recite wherein the precoder report for each cooperating site is independent of the precoder report for the other cooperating sites. Monogioudis teaches wherein the precoder report for each cooperating site is independent of the precoder report for the other cooperating sites (The first precoder weight of the mobile station W 100 p 220 may be different than the second precoder weight W 100 p 210 since the precoder weights correspond to the two independent channels from the two base stations, Para. 24, FIG. 1). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Monogioudis with the limitations of claim 1 of U.S. Patent No. 10,615,851 since Monogioudis provides a technique for base stations to perform joint beamforming, which can be introduced in the limitations of claim 1 of U.S. Patent No. 10,615,851 to permit transmitting sites to cooperate more efficiently through joint beamforming. Claim 22 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 10,615,851 in view of Monogioudis. Although the claims at issue are not identical, they are not patentably distinct from each other because both conflicting claims recite at one or more of the cooperating sites, applying a phase adjustment to the transmission. Claim 30 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 11 of U.S. Patent No. 10,615,851 in view of Monogioudis et al. (Pub. No.: US 20100009717 A1), hereafter referred to as Monogioudis. Although the claims at issue are not identical, they are not patentably distinct from each other because both conflicting claims recite A communications system comprising: a plurality of transmitting sites, at least two of the plurality of the transmitting sites designated as cooperating sites and configured to transmit a data stream to a mobile terminal, each cooperating site comprising at least two antennas and further configured to: receive a precoder report from the mobile terminal for each cooperating site wherein the precoder report is selected from a precoder set; and transmit the data stream to the mobile terminal using a beam formed by the cooperating site's antennas. Claim 11 of U.S. Patent No. 10,615,851 fails to clearly recite wherein the precoder report for each cooperating site is independent of the precoder report for the other cooperating sites. Monogioudis teaches wherein the precoder report for each cooperating site is independent of the precoder report for the other cooperating sites (The first precoder weight of the mobile station W 100 p 220 may be different than the second precoder weight W 100 p 210 since the precoder weights correspond to the two independent channels from the two base stations, Para. 24, FIG. 1). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Monogioudis with the limitations of claim 11 of U.S. Patent No. 10,615,851 since Monogioudis provides a technique for base stations to perform joint beamforming, which can be introduced in the limitations of claim 11 of U.S. Patent No. 10,615,851 to permit transmitting sites to cooperate more efficiently through joint beamforming. Claim 32 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 11 of U.S. Patent No. 10,615,851 in view of Monogioudis. Although the claims at issue are not identical, they are not patentably distinct from each other because both conflicting claims recite one or more of the cooperating sites is further configured to apply a phase adjustment to the transmission. Claim 21 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 8,693,442 in view of Monogioudis et al. (Pub. No.: US 20100009717 A1), hereafter referred to as Monogioudis. Although the claims at issue are not identical, they are not patentably distinct from each other because both conflicting claims recite A method of transmitting a data stream to a mobile terminal in a communications network including a plurality of transmitting sites, comprising: designating at least two of the plurality of transmitting sites as cooperating sites, each cooperating site comprising at least two antennas; receiving a precoder report from the mobile terminal for each cooperating site; and at each cooperating site, transmitting the data stream to the mobile terminal using a beam formed by the cooperating site's antennas. Claim 1 of U.S. Patent No. 8,693,442 fails to clearly recite wherein the precoder report is selected from a precoder set and wherein the precoder report for each cooperating site is independent of the precoder report for the other cooperating sites. Monogioudis teaches wherein the precoder report is selected from a precoder set (A Nominal Precoder Matrix that is known by a mobile station 100 allows the mobile station 100 to calculate the precoder weights communicated to the base station 210 and 220. The Nominal Precoder Matrix may be a unitary matrix or any other matrix that is a-priori known to both the mobile station 100 and base stations 210 and 210. In many instances, the Nominal Precoder Matrix is downloadable to the mobile station upon network entry, Para. 20, FIG. 1. The elements of the joint channel matrix are the feedback precoder weights, Para. 28, FIG. 1) and wherein the precoder report for each cooperating site is independent of the precoder report for the other cooperating sites (The first precoder weight of the mobile station W 100 p 220 may be different than the second precoder weight W 100 p 210 since the precoder weights correspond to the two independent channels from the two base stations, Para. 24, FIG. 1). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Monogioudis with the limitations of claim 1 of U.S. Patent No. 8,693,442 since Monogioudis provides a technique for base stations to perform joint beamforming, which can be introduced in the limitations of claim 1 of U.S. Patent No. 8,693,442 to permit transmitting sites to cooperate more efficiently through joint beamforming. Claim 22 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 3 of U.S. Patent No. 8,693,442 in view of Monogioudis.

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 pre-AIA 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 – (e) the invention was described in (1) an application for patent, published under section 122(b), by another filed in the United States before the invention by the applicant for patent or (2) a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent, except that an international application filed under the treaty defined in section 351(a) shall have the effects for purposes of this subsection of an application filed in the United States only if the international application designated the United States and was published under Article 21(2) of such treaty in the English language. Claim(s) 21, 24 and 30-31 is/are rejected under pre-AIA 35 U.S.C. 102(e) as being anticipated by Monogioudis et al. (Pub. No.: US 20100009717 A1), hereafter referred to as Monogioudis. In regard to Claim 21, Monogioudis teaches A method of transmitting a data stream to a mobile terminal (mobile station 100, Para. 19, FIG. 1) in a communications network including a plurality of transmitting sites (the MIMO system includes more than two base stations, Para. 19, FIG. 1), comprising: designating at least two of the plurality of transmitting sites as cooperating sites (Referring to FIG. 1, the MIMO system includes a base station 210, and a controlling base station 220.

Claim Rejections - 35 USC § 103 The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under pre-AIA 35 U.S.C. 103(a) are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 22-23 and 32-33 is/are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Monogioudis in view of Fukuoka et al. (Pub. No.: US 20090103648 A1), hereafter referred to as Fukuoka.

The phase rotation difference between pilot symbols P1 and P2 and the phase rotation difference between data symbols S1 and S1' are both ΦA=Φ2-Φ1, Para. 68, FIG. 5A). It would have been obvious to one of ordinary skill in the art at the time of the invention to combine the teachings of Fukuoka with the teachings of Monogioudis since Fukuoka provides a technique for phase rotation of signals in an arraignment involving a mobile station in the coverage of two base stations, which can be introduced into the system of Monogioudis to permit a base station to alter signal transmissions toward a mobile with respect to signals of a neighboring base station for improving communications with the mobile station.
