Office Action

§112 §DP
DETAILED ACTION Claims 16-22 are currently pending in the application. Claims 1-15 are original claims to patent US 10,522,168 B2 to Nagel et al. (herein Nagel ‘168) and claims 16-22 are newly added claims. Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Reissue Applications For reissue applications filed before September 16, 2012, all references to 35 U.S.C. 251 and 37 CFR 1.172, 1.175, and 3.73 are to the law and rules in effect on September 15, 2012. Where specifically designated, these are “pre-AIA ” provisions. For reissue applications filed on or after September 16, 2012, all references to 35 U.S.C. 251 and 37 CFR 1.172, 1.175, and 3.73 are to the current provisions. Applicant is reminded of the continuing obligation under 37 CFR 1.178(b), to timely apprise the Office of any prior or concurrent proceeding in which Patent No. 10,522,168 is or was involved. These proceedings would include any trial before the Patent Trial and Appeal Board, interferences, reissues, reexaminations, supplemental examinations, and litigation. Applicant is further reminded of the continuing obligation under 37 CFR 1.56, to timely apprise the Office of any information which is material to patentability of the claims under consideration in this reissue application. These obligations rest with each individual associated with the filing and prosecution of this application for reissue. See also MPEP §§ 1404, 1442.01 and 1442.04. Information Disclosure Statement The information disclosure statements (IDS)s submitted on 08/08/2024, 11/26/2024, 02/15/2025, and 05/14/2026 are considered by the examiner in accordance with 37 CFR 1.97, 37 CFR 1.98, MPEP 609, and MPEP 1406, to the fullest extent of the items presented including any concise explanation. Documents not meeting particular criteria are lined through and not considered. Several documents were not found in the record and therefore lined through as they could not be considered. ADS Objections The ADS filed 08/08/2024 is objected to because of the following informalities in the Domestic Benefit section: (1) in the Domestic Benefit section, the filing date of application 18/797,996 should be corrected to 2024-08-08; and (2) the applicant information section should indicate “Assignee”, as the patent to be reissued (Nagel ‘168) is already assigned. The corrected ADS should comply with 37 CFR 1.76(c)(2), which requires that any changes to an ADS be identified with markings (see Reissue Application Filing Guide at http://www.uspto.gov/sites/default/files/forms/uspto_reissue_ads_guide_Sept2014.pdf for more information). Applicant can also use the Corrected Web-based ADS. See the Quick Start Guide for Corrected Web-based ADS at https://www.uspto.gov/sites/default/files/documents/Corrected-WebADS-QSG.pdf. Consent of Assignee This application is objected to under 37 CFR 1.172(a) as lacking the written consent of all assignees owning an undivided interest in the patent. The consent of the assignee must be in compliance with 37 CFR 1.172. See MPEP § 1410.01. Specifically, in accordance with MPEP 1410.02 and MPEP 325, the consent of assignee must be signed by a party authorized to act on behalf of the assignee. A person having a title that does not clearly set forth that person as an officer of the assignee is not presumed to have authority to sign the submission on behalf of the assignee. In this application, the consent of assignee has been signed by “TITLE: Authorized Signatory”. Specifically, MPEP 1410.02 states that “The consent of assignee must be signed by a party authorized to act on behalf of the assignee. For applications filed on or after September 16, 2012, the consent may be signed by the assignee or a patent practitioner of record. Where the assignee is a juristic entity, the consent may be signed by a person in the organization having apparent authority to sign on behalf of the organization, or a person who makes a statement of authorization to act on behalf of the assignee. For a discussion of parties authorized to act on behalf of the assignee, see MPEP § 325 (for applications filed on or after September 16, 2012).” MPEP 325 specifically states that, “The submission may be signed by a person in the organization having apparent authority to sign on behalf of the organization. 37 CFR 3.73(d)(2). An officer (chief executive officer, president, vice-president, secretary, or treasurer) is presumed to have authority to sign on behalf of the organization…A person having a title (administrator, general counsel) that does not clearly set forth that person as an officer of the assignee is not presumed to have authority to sign the submission on behalf of the assignee. In this application, the consent of assignee has been signed by “Team Leader Patents” which does not meet the requirement of 37 CFR 3.73(d)(2). See MPEP 325 for a list of persons in an organization having the authority to sign on behalf of the organization. A proper assent of the assignee in compliance with 37 CFR 1.172 and 3.73 is required in reply to this Office action. Oath/Declaration Objections The reissue oath/declaration filed 10/14/2024 for this application is defective (see 37 CFR 1.175 and MPEP § 1414) and objected to because it fails: (1) it is not properly signed by the assignee of the entire interest (37 CFR 1.175(c)), the declaration is signed by the same person lacking apparent authority to sign on behalf of the organization as found in the Consent of Assignee (see above discussion objecting to the Consent of Assignee). Claim Rejections – 35 USC § 251 Claims 16-22 are rejected as being based upon a defective reissue declaration under 35 U.S.C. 251 as set forth above. See 37 CFR 1.175 and MPEP 1414. The nature of the defect(s) in the declaration is set forth in the discussion above in this Office action (see Oath/Declaration Objections): (1) it is not properly signed by the assignee of the entire interest (37 CFR 1.175(c)). Specification Objections The amendment to the Specification of 08/08/2024 is defective because of the following: (1) the cross-referenced continuation reissue applications are not properly identified by application number (see 37 CFR 1.177(a)). Additionally, the attorney docket number is not necessary for identifying the cross-referenced continuation reissue applications. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 22 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 22 recites the limitation "the method" in the preamble. There is insufficient antecedent basis for this limitation in the claim. 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.

Related Patents 8,386,268 Claims 16-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-9 of U.S. Patent No. 8,386,268 to Nagel et al. (herein Nagel ‘268) in view of US 6,680,972 B1 to Liljeryd et al. (herein Liljeryd ‘972) in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. (herein Nagel ‘948). Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims read upon the claimed features of the reference patent/application as follows: instant claim 16 is found in at least claim 1 of Nagel ‘268 (compare: the claimed “patch generator” to the “patch generator” of Nagel ‘268; the claimed “spectral converter” to the “first converter” of Nagel ‘268; the claimed “signal processor” to the “manipulator” of Nagel ‘268; and the claimed “combiner” to the “combiner” of Nagel ‘268). Additionally, Liljeryd ‘972 shows transposing/patching implemented using time-domain transposers (Liljeryd ‘972: column 12, lines 1-12). It would have been obvious to one of ordinary skill in the art at the time of invention to implement the spectral domain patching of Nagel ‘268 as time domain patching with filterbank for adjusting the envelope as suggested by the teachings of Liljeryd ‘972. This implementation would have been obvious because one of ordinary skill in the art would have found: Liljeryd ‘972 “presents the opportunity to adjust the envelope of the created spectrum while maintaining the simplicity and low computational cost of a time domain transposer” (Liljeryd ‘972: column 12, lines 1-8); and both references are analogously directed to spectral bandwidth replication patching. Further, Nagel ‘948 shows “wherein the raw signal processor is adapted to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions” (Nagel ‘948: claim 1, raw signal processor and spectral band replication parameters; 5:42-6:50, discussing spectral signal processor adapted to process by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions). It would have been obvious to implement the claimed manipulator (i.e. raw signal processor) and spectral band replication parameters of Nagel ‘268 to process the spectral representation (i.e. raw signal spectral representation) in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions as shown in Nagel ‘948. This implementation would have been obvious because one of ordinary skill in the art would have found: the analogous Nagel ‘268 (patching algorithms control) claims similar patching algorithms as to those claimed by Nagel ‘948; Nagel ‘268 claims a spectral band replication parameter (see claim 1); as such, the implementation of is an application of a known element/technique yielding a predictable result using an acceptable piece of prior art (implementing SBR parameters in the context of similar patching algorithms). The remaining instant claims 17-22 are similarly not patentably distinct from the claims 1-9 of Nagel ‘268 in view of Liljeryd ‘972 in view of Nagel ‘948. 9,076,433 Claims 16-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-12 of U.S. Patent No. 9,076,433 to Nagel et al. (herein Nagel ‘433) in view of US 6,680,972 B1 to Liljeryd et al. (herein Liljeryd ‘972) claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. (herein Nagel ‘948). Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims read upon the claimed features of the reference patent/application as follows: instant claim 16 is found in at least claim 1 of Nagel ‘433 (compare: the claimed “patch generator” to the “patch generator” of Nagel ‘433; the claimed “spectral converter” to the “first converter” of Nagel ‘433; the claimed “signal processor” to the “manipulator” of Nagel ‘433; and the claimed “combiner” to the “combiner” of Nagel ‘433). Additionally, Liljeryd ‘972 shows transposing/patching implemented using time-domain transposers (Liljeryd ‘972: column 12, lines 1-12). It would have been obvious to one of ordinary skill in the art at the time of invention to implement the spectral domain patching of Nagel ‘433 as time domain patching with filterbank for adjusting the envelope as suggested by the teachings of Liljeryd ‘972. This implementation would have been obvious because one of ordinary skill in the art would have found: Liljeryd ‘972 “presents the opportunity to adjust the envelope of the created spectrum while maintaining the simplicity and low computational cost of a time domain transposer” (Liljeryd ‘972: column 12, lines 1-8); and both references are analogously directed to spectral bandwidth replication patching. Further, Nagel ‘948 shows, wherein the raw signal processor is adapted to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions. It would have been obvious to combine Nagel ‘948 with Nagel ‘433 for the same reasons as discussed above under Nagel ‘268. The remaining instant claims 17-22 are similarly not patentably distinct from the claims 1-9 of Nagel ‘433 in view of Liljeryd ‘972 in view of Nagel ‘948. RE50,601; RE50,676; RE50,692; RE50,693; RE50,710; RE50,767; RE50,780 As reissues of Nagel ‘433 with corresponding limitations, claims 16-21 are rejected on the grounds of nonstatutory double patenting (for similar reasons as above under Nagel ‘433) as being unpatentable over each of the following: (1) claims 13-18 of U.S. Patent No. RE50,601 to Nagel et al. (herein Nagel ‘601) in view of US 6,680,972 B1 to Liljeryd et al. in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (2) claims 13-18 of U.S. Patent No. RE50,676 to Nagel et al. (herein Nagel ‘676) in view of US 6,680,972 B1 to Liljeryd et al. in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (3) claims 1-8 of U.S. Patent No. RE50,692 to Nagel et al. (herein Nagel ‘692) in view of US 6,680,972 B1 to Liljeryd et al. in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (4) claims 13-21 of U.S. Patent No. RE50,693 to Nagel et al. (herein Nagel ‘693) in view of US 6,680,972 B1 to Liljeryd et al. in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (5) claims 13-17 of U.S. Patent No. RE50,710 to Nagel et al. (herein Nagel ‘710) in view of US 6,680,972 B1 to Liljeryd et al. in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (6) claims 13-18 of U.S. Patent No. RE50,767 to Nagel et al. (herein Nagel ‘767) in view of US 6,680,972 B1 to Liljeryd et al. in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; and (7) claims 13-17 of U.S. Patent No. RE50,780 to Nagel et al. (herein Nagel ‘780) in view of US 6,680,972 B1 to Liljeryd et al in further view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. Family Patents/Applications 8,731,948 Claims 16-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. (herein Nagel ‘948). Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims read upon the claimed features of the reference patent/application as follows: instant claim 16 is found in at least claim 1 of Nagel ‘948 (compare: the claimed “patch generator” to the “patch generator” of Nagel ‘948; the claimed “spectral converter” to the “spectral converter” of Nagel ‘948; the claimed “signal processor” to the “signal processor” of Nagel ‘948; and the claimed “combiner” to the “combiner” of Nagel ‘948). Additionally, Nagel ‘948 shows “wherein the raw signal processor is adapted to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions” (Nagel ‘948: claim 1, raw signal processor and spectral band replication parameters; 5:42-6:50, discussing spectral signal processor adapted to process by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions). Alternatively, any one of US 10,014,000 (Nagel ‘000), US 18/797,996 (Nagel ‘996), US 18/798,057 (Nagel ‘057, US 18/798,128 (Nagel ‘128), US 18/798,194 (Nagel ‘194), US 18/798,242 (Nagel ‘242), US 18/798,399 (Nagel ‘399), US 18/798,479 (Nagel ‘479), and US 18/798,516 (Nagel ‘516) also disclose the afore-mentioned limitation (see corresponding descriptions). It would have been obvious to implement the claimed raw signal processor and spectral band replication parameters of Nagel ‘948 to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions. This would have been obvious as any of Nagel ‘948 and/or the other listed patents/applications claiming a benefit to Nagel ‘948 described such an arrangement as an implementation. The remaining instant claims 17-22 are similarly not patentably distinct from the claims 1-10 of Nagel ‘948. 10,014,000 Claims 16-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. (herein Nagel ‘948) in view of claims 1-8 of U.S. Patent No. 10,014,000 to Nagel et al. (herein Nagel ‘000). Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims read upon the claimed features of the reference patent/application as follows: for the same reasons as discussed in the preceding Nagel ‘948 double patenting rejection. Claim 1 of Nagel ‘000 outputs audio data stream, the claim showing the complementary encoding of the audio data stream that Nagel ‘948 claims to decode/synthesize) in the same context of patching algorithms. It would have been obvious to one of ordinary skill in the art at the time of invention to implement the patching algorithms of Nagel ‘000 and Nagel ‘948 in both encoding and decoding operations for a data stream as suggested by the teachings of Nagel ‘000 and Nagel ‘948, both showing “wherein the raw signal processor is adapted to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions”. This implementation would have been obvious because one of ordinary skill in the art would have found: the analogous Nagel ‘000 (same inventors) claims patching algorithms similar to those claimed by Nagel ‘948; an encoded stream must be decoded and a decoded stream must have been encoded. The remaining instant claims 17-22 are similarly not patentably distinct from the claims 1-10 of Nagel ‘948 in view of claims 1-8 of Nagel ‘000. 18/797,996; 18/798,057; 18/798,128; 18/798,194; 18/798,242; 18/798,399; 18/798,479; 18/798,516 Claims 16-22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 16-28 of U.S. Patent Application 18/797,996 to Nagel et al. (herein Nagel ‘996) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. (herein Nagel ‘948). Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims read upon the claimed features of the reference patent/application as follows: instant claim 16 is found in at least claim 1 of Nagel ‘996 (compare: the claimed “patch generator” to the “patch generator” of Nagel ‘996; the claimed “spectral converter” to the “spectral converter” of Nagel ‘996; the claimed “signal processor” to the “signal processor” of Nagel ‘996; and the claimed “combiner” to the “combiner” of Nagel ‘996). Additionally, Nagel ‘948 shows the claimed “wherein the raw signal processor is adapted to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions” (see above discussion under Nagel ‘948 double patenting rejection). It would have been obvious to implement the claimed raw signal processor and spectral band replication parameters of Nagel ‘996 to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions as suggested by the teachings of Nagel ‘948. This implementation would have been obvious because one of ordinary skill in the art would have found: the analogous Nagel ‘996 (a descendant application of Nagel ‘948) claims similar patching algorithms as to those claimed by Nagel ‘948 albeit with differing scopes; as such, the implementation of is an application of a known element/technique yielding a predictable result using an acceptable piece of prior art. The remaining instant claims 17-22 are similarly not patentably distinct from the claims 16-28 of Nagel ‘996 in view of claims 1-10 of Nagel ‘948. As reissues of Nagel ‘168 with corresponding limitations (ultimately corresponding to Nagel ‘948), claims 16-22 are rejected on the grounds of nonstatutory double patenting (for similar reasons as above under Nagel ‘996) as being unpatentable over each of the following: (1) claims 16-22 of co-pending U.S. Patent Application 18/798,057 to Nagel et al. (herein Nagel ‘057) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (2) claims 16-20 of co-pending U.S. Patent Application 18/798,128 to Nagel et al. (herein Nagel ‘128) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (3) claims 16-22 of co-pending U.S. Patent Application 18/798,194 to Nagel et al. (herein Nagel ‘194) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (4) claims 16-22 of co-pending U.S. Patent Application 18/798,242 to Nagel et al. (herein Nagel ‘242) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (5) claims 16-22 of co-pending U.S. Patent Application 18/798,399 to Nagel et al. (herein Nagel ‘399) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; (6) claims 16-22 of co-pending U.S. Patent Application 18/798,479 to Nagel et al. (herein Nagel ‘479) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al.; and (7) claims 16-21 of co-pending U.S. Patent Application 18/798,516 to Nagel et al. (herein Nagel ‘516) in view of claims 1-10 of U.S. Patent No. 8,731,948 to Nagel et al. These are provisional nonstatutory double patenting rejections. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: the prior art of record does not teach or reasonably suggest the combined limitations of the independent claims. For example, the prior art of record does not show the combined limitations of claim 16 to a method for generating a synthesis audio signal comprising a first frequency band and a second replicated frequency band derived from the first frequency band, comprising: performing at least two different patching algorithms, wherein each patching algorithm generates a raw signal comprising signal components in the second replicated frequency band using an audio signal comprising signal components in the first frequency band, and wherein the patching is performed such that one of the at least two different patching algorithms is selected in response to a control information for a first time portion and the other of the at least two different patching algorithms is selected in response to the control information for a second time portion different from the first time portion to acquire the raw signal for the first and the second time portion; converting the raw signal into a raw signal spectral representation; processing the raw signal spectral representation in response to spectral domain spectral band replication parameters to acquire an adjusted raw signal spectral representation; and combining the audio signal comprising signal components in the first band or a signal derived from the audio signal with the adjusted raw signal spectral representation or with a further signal derived from the adjusted raw signal spectral representation to acquire the synthesis audio signal, wherein the raw signal processor is adapted to process the raw signal spectral representation in response to the spectral domain spectral band replication parameters by means of a spectral envelope adjustment at a frequency resolution which is controlled via the data stream in a manner enabling changing the frequency resolution between two time portions with selecting the patching algorithm for the two time portions to be equal for the two time portions. The remaining claims have allowable subject matter for similar reasons as to claim 16. As allowable subject matter has been indicated, applicant's reply must either comply with all formal requirements or specifically traverse each requirement not complied with. See 37 CFR 1.111(b) and MPEP § 707.07(a).
