Office Action

§DP
DETAILED ACTION This action is in response to communications filed 11/27/2024: Claims 1-20 are pending 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 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 12192739. Although the claims at issue are not identical, they are not patentably distinct from each other. For example: Regarding claim 1, 12192739 teaches a computer-implemented method (claim 1, a computer-implemented method) comprising: determining a target location in an environment (claim 1, determining a target location in an environment); computing a first coherence value indicating a level of coherence between a first sub-band impulse response and a second sub-band impulse response for a first frequency sub-band, the first and second sub-band impulse responses being associated with corresponding locations that are proximate to the target location (claim 1, determining a set of sub-band impulse responses for a first frequency sub-band, each sub-band impulse response in the set of sub-band impulse responses being associated with a corresponding location that is proximate to the target location…computing a first coherence value indicating a level of coherence between sub-band impulse responses in the first pair); combining the first and second sub-band impulse responses using non-linear interpolation when the first coherence value is below a coherence threshold (claim 1, determining that the first coherence value is below a coherence threshold…in response to determining that the first coherence value is below the coherence threshold, combining the sub-band impulse responses in the first pair using a non-linear interpolation technique…) or using linear interpolation when the first coherence value is equal to or above the coherence threshold to generate an estimated impulse response for the first frequency sub-band for the target location (claim 6, in response to determining that the second coherence value is equal to or above the coherence threshold, combining the sub-band impulse responses in the second pair using a linear interpolation technique to generate a second estimated impulse response for the second frequency sub-band for the target location); generating, based at least on the estimated impulse response, a filter for a speaker (claim 1, generating, based at least on the estimated impulse response, a filter for a speaker); filtering, by the filter, an audio signal to generate a filtered audio signal (claim 1, filtering, by the filter, an audio signal to generate a filtered audio signal); and causing the speaker to output the filtered audio signal (claim 1, causing the speaker to output the filtered audio signal). The remaining independent and/or dependent claims are similarly rejected using one or more claims of the patent (whether alone or in combination). Allowable Subject Matter Claims 1-20 are allowable upon overcoming the above rejection(s). The following is an examiner’s statement of reasons for allowance: regarding claims 1, 10, and 17, the prior art or combination thereof fails to disclose and make obvious the invention as a whole. A previous rationale for allowance was provided in the parent application (NOA mailed 8/28/2024) and considered to be similarly applicable in the current application and therefore the same rationale will not be copied here. The respective dependent claims are also allowable as they depend upon an allowable parent claim. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Refer to PTO-892, Notice of References Cited for a listing of analogous art.
