§102 §103 §DP
CTFR 18/514,517 CTFR 76599 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 08-33 AIA 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. 08-34 AIA Claim s 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim s 1, 14, and 17 of U.S. Patent No. 11,856,565 B2 . Although the claims at issue are not identical, they are not patentably distinct from each other because comparing claims 1, 14, and 18 of the application with claims 1, 14, and 17 of the patent claims 1, 14, and 18 of the application are anticipated by patent claims 14, and 17 in that claims 1, 14, and 17 of the patent contain all the limitations of claims 1, 14, and 18 of the application. Claims 1, 14, and 18 of the application therefore are not patently distinct from the earlier patent claims as such are unpatentable for obvious-type double patenting .

Patentability shall not be negated by the manner in which the invention was made. 07-21-aia AIA Claim s 12 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Patil (same as above) in view of Ibars Casas et al. (US 12,494,865 B2) hereinafter Ibars . Regarding claim 12 – Patil discloses claim 1. Patil does not explicitly disclose transceiver circuitry coupled to the processing circuitry, the transceiver circuitry coupled to two or more patch antennas for receiving signaling in accordance with a multiple-input multiple-output (MIMO) technique. Ibars discloses transceiver circuitry coupled to the processing circuitry, the transceiver circuitry coupled to two or more patch antennas for receiving signaling in accordance with a multiple-input multiple-output (MIMO) technique, refer to paragraph (60) - a microstrip antenna, such as a rectangular microstrip patch antenna or a quarter-wave patch antenna , also, paragraph [0093] - indicate which RUs are allocated for MU-MIMO transmission, also, paragraph (342) - wireless transceiver 2226 can be a Wi-Fi transceiver, a Bluetooth transceiver, or a mobile network transceiver such as a 3G, 4G, or Long Term Evolution (LTE) transceiver , also, paragraph (470) - frequency region require high spectral efficiency enabled by multi-user MIMO (MU-MIMO) At the time of the invention before the effective filing date of the application it would have been obvious to an ordinary person of skill in the art to combine Patil with Ibars to provide Patil with transceiver circuitry coupled to the processing circuitry, the transceiver circuitry coupled to two or more patch antennas for receiving signaling in accordance with a multiple-input multiple-output (MIMO) technique. Suggestion/motivation is that Patil discloses multiple antennas and MIMO, refer to [0004] - multiple concurrent communication links (MIMO) , also, refer to paragraph [0108] - the wireless communication device 500 can include, or be coupled with, multiple transmit antennas (each with a corresponding transmit chain) and multiple receive antennas , also, Figure 6A and paragraph [0111] - The AP 602 also includes multiple antennas 620 coupled with the wireless communication device 610 to transmit and receive wireless communications .

Patil does not explicitly disclose transceiver circuitry coupled to the processing circuitry, the transceiver circuitry coupled to two or more microstrip antennas for receiving signaling in accordance with a multiple-input multiple-output (MIMO) technique. Ibars discloses transceiver circuitry coupled to the processing circuitry, the transceiver circuitry coupled to two or more microstrip antennas for receiving signaling in accordance with a multiple-input multiple-output (MIMO) technique, refer to paragraph (60) - a microstrip antenna, such as a rectangular microstrip patch antenna or a quarter-wave patch antenna , also, paragraph [0093] - indicate which RUs are allocated for MU-MIMO transmission, also, paragraph (342) - wireless transceiver 2226 can be a Wi-Fi transceiver, a Bluetooth transceiver, or a mobile network transceiver such as a 3G, 4G, or Long Term Evolution (LTE) transceiver , also, paragraph (470) - frequency region require high spectral efficiency enabled by multi-user MIMO (MU-MIMO) At the time of the invention before the effective filing date of the application it would have been obvious to an ordinary person of skill in the art to combine Patil with Ibars to provide Patil with the transceiver circuitry coupled to two or more microstrip antennas for receiving signaling in accordance with a multiple-input multiple-output (MIMO) technique. Suggestion/motivation is that Patil discloses multiple antennas and MIMO, refer to [0004] - multiple concurrent communication links (MIMO) , also, refer to paragraph [0108] - the wireless communication device 500 can include, or be coupled with, multiple transmit antennas (each with a corresponding transmit chain) and multiple receive antennas , also, Figure 6A and paragraph [0111] - The AP 602 also includes multiple antennas 620 coupled with the wireless communication device 610 to transmit and receive wireless communications . The benefit being an inexpensive small antennas can be used to provide MIMO communications . Response to Arguments 07-37 AIA Applicant's arguments filed 4/6/26 have been fully considered but they are not persuasive. The examiner respectfully disagrees . Applicants argue on page 8 of the response – “ Patil simply does not disclose that the "AP" of claim 1 includes in a "first beacon frame" the "channel switch announcement element, the extended channel switch announcement element, the max channel switch time element, or the quiet channel element" of the "affected AP" "in response to" the "affected AP" "transmitting a second beacon frame," which includes these elements. ” The examiner respectively disagrees. The examiner relies on the reference Patil (US 2021/0321243 A1) paragraphs [0007] and [0009] to reject the above element. Paragraphs [0007] and [0009] disclose the following – “ the method may also include receiving, from a respective secondary AP of the AP MLD, a notification of a critical update for the respective secondary AP, also, refer to paragraph [0009] - the one or more operation parameters include at least one of a channel switch announcement (CSA), an extended CSA, a wide bandwidth CSA, enhanced distributed channel access (EDCA) parameters, multi-user (MU) EDCA parameters, a quiet time element, ” The examiner would like to point out the argument states - "first beacon frame" – the claim refers to a “ second beacon frame ” and the term is used in conjunction with an “OR” statement in which the examiner is only required to find one of the elements referred to in the “OR” statement. As an aside - referring to paragraph [0003] - An AP periodically broadcasts beacon frames to enable any STAs within wireless range of the AP to establish or maintain a communication link with the WLAN , also, refer to paragraph [0006] - The frame may be one of a beacon frame, a probe response frame, an association response frame, a reassociation response frame, or a fast initial link setup (FILS) discovery frame . Since the examiner was not required to find a second beacon frame as part of the “OR” statement – other elements were relied upon. Going back to the claim element in question - Paragraph [0007] – refers to “ a respective secondary AP of the AP MLD , (the affected AP), also, refer to paragraph [0009] - a channel switch announcement (CSA), and a quiet time element, both of which meet the requirements of the claim. The applicants argue on page 8 or the response – “ During the interviews, questions arose about the term "affected AP." The term "affected" is used in the specification at paragraph [00139] with "The affected link in FIGS. 17 and 18 correspond to 5 GHZ band 838, in accordance with the examples above." In FIGS. 17 and 18, the links are referred to as "Link 1 (AP1)" and "Link 2 (AP2)." The term "affected" can be interpreted as the entity that controls the link, which here is an AP. ” Specification paragraph [00139] – “ [00139] FIG. 18 illustrates the operation 1800 of an AP carrying a Channel Switch Announcement element to signal channel switching on another link, in accordance with some embodiments. AP1 and AP2 are part of the same ML AP logical entity 808. Quiet count is a value indicated by quiet count 1206 or quiet count 1308, in accordance with some embodiments. Time increases from left to right. The affected link in FIGS. 17 and 18 corresponds to 5 GHZ band 838, in accordance with the examples above. ” The paragraph only mentions an affected link not an affected AP . There is a difference and the examiner believes the affected AP in the claim does not have support in the specification. The affected link in the paragraph refers to channel quieting on another link not an AP. The examiner believes the rejection to be reasonable, therefore this action is made final. If the applicants want a telephone interview to advance prosecution, please call the examiner . Conclusion 07-39 AIA THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
