Office Action

§102
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 . 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 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. DETAILED ACTION This is an AIA application filed October 12, 2023. The earliest effective filing date of this AIA application is seen as March 31, 2020, the date of the earliest priority application (United States provisional patent application serial number 63/002,981) for any claims which are fully supported under 35 U.S.C. 112(a) by the provisional application. The same is similarly true for the following United States provisional or non-provisional patent application(s): United States patent application serial number 17/962,831 filed October 10, 2022, now U.S. Patent No. 11,789,209; and United States patent application serial number 17/190,488 filed March 3, 2021, now U.S. Patent No. 11,487,063*. (*) Data provided by applicant is not consistent with PTO record. The effective filing date of this AIA application is seen as October 12, 2023, the actual filing date, for any claims that are not fully supported by the foregoing provisional or non-provisional application(s). The present application is also related to the applications giving rise to the following patent publication(s) (please note that redundancies are generally present and no guarantees are given regarding completeness): Office Application App. Date Pub. # Pub. Date US 17190488 03/03/2021 US 20210302660 A1 US 11487063 B2 09/30/2021 11/01/2022 JP 2021050156 03/24/2021 JP 2021164162 A JP 7703346 B2 10/11/2021 07/07/2025 EP 21166069 03/30/2021 EP 3890219 A1 EP 3890219 B1 10/06/2021 07/05/2023 CN 202110352099 03/31/2021 CN 113473269 A 10/01/2021 US 17962831 10/10/2022 US 20230034669 A1 US 11789209 B2 02/02/2023 10/17/2023 JP 2025106029 06/23/2025 JP 2025134922 A 09/17/2025 The claims filed September 24, 2025 are entered, currently outstanding, and subject to examination. This action is in response to the filing of the same date. The current status and history of the claims is summarized below: Last Amendment/Response Previously Amended: 1-4, 10, 11, 13-16, 19, & 20 1, 7, 13, 18, & 20 Cancelled: none none Withdrawn: none none Added: none none Claims 1-20 are currently pending and outstanding. Regarding the last reply: Claims 1-4, 10, 11, 13-16, 19, and 20 were amended. No claims were cancelled. No claims were withdrawn. No claims were added. Claims 1-20 are currently outstanding and subject to examination. This is a final action and is the fourth action on the merits. Allowable subject matter is not indicated below. Often, in the substance of the action below, formal matters are addressed first, claim rejections second, and any response to arguments third. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on September 24, 2025 has been entered. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Applicant must provide the same terminology/vocabulary/phrasing in the specification that is present in the claims. At least one term or phrase is missing from the specification present in the claim(s). Correction is required as the following amendment(s)/text in the claims find(s) no antecedent in the specification. Claim(s) Antecedent Missing For 1, 2, 10, 11, 13, 14, 19, 20 "plurality of cables" 1, 13, 20 "plurality of cables connecting one or more transmission sites" As set forth in MPEP § 608.01(o): The meaning of every term used in any of the claims should be apparent from the descriptive portion of the specification with clear disclosure as to its import; and in mechanical cases, it should be identified in the descriptive portion of the specification by reference to the drawing, designating the part or parts therein to which the term applies. A term used in the claims may be given a special meaning in the description. See MPEP § 2111.01 and § 2173.05(a). Usually the terminology of the original claims follows the nomenclature of the specification, but sometimes in amending the claims or in adding new claims, new terms are introduced that do not appear in the specification. The use of a confusing variety of terms for the same thing should not be permitted. . . . While an applicant is not limited to the nomenclature used in the application as filed, he or she should make appropriate amendment of the specification whenever this nomenclature is departed from by amendment of the claims so as to have clear support or antecedent basis in the specification for the new terms appearing in the claims. This is necessary in order to insure [sic, ensure] certainty in construing the claims in the light of the specification, Ex parte Kotler, 1901 C.D. 62, 95 O.G. 2684 (Comm’r Pat. 1901). See 37 CFR 1.75 and MPEP §§ 608.01(i), § 1302.01. Consequently, identity between terms and phrases in the specification and claims is preferred and is seen as mandatory to ensure “certainty in construing the claims in the light of the specification”. Further, under 37 C.F.R. § 1.121(e) regarding disclosure consistency in making amendments: The disclosure must be amended, when required by the Office, to correct inaccuracies of description and definition, and to secure substantial correspondence between the claims, the remainder of the specification, and the drawings. Examiner considers direct correspondence between the specification and the claims to be important with respect to determining the scope of the claims. Examiner strongly urges Applicant to review its claims with a fine-toothed comb and scrutinize them for any discrepancies between claim language and language that is used in the written description/specification as originally filed. Applicant is responsible for what it drafts. Discrepancies may be interpreted to Applicant’s detriment. Special Definitions for Claim Language - MPEP § 2111.01(IV) No special definitions are seen as present in the specification regarding the language used in the claims. Consequently, the words and phrases of the claims are given their plain meaning. MPEP §§ 2173.01, 2173.05(a), and 2111.01. If special definitions are present, Applicant should bring those to the attention of the examiner and the prosecution history with its next response in a manner both specific and particular. In doing so, there will be no mistake, confusion, and/or ambiguity as to what constitutes the special definition(s). To date, Applicant has provided no indication of special definitions. 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 1-20 are rejected under 35 U.S.C. § 102(a)(1) as being anticipated by U.S. Patent Application Publication No. 20200052788 of Grubb et al. (Grubb). With respect to claim 1, Grubb discloses a computer implemented method (Figs. 1, 2; ¶ 12, “The invention can be implemented in numerous ways, including as a process; an apparatus; a system; a composition of matter; a computer program product embodied on a computer readable storage medium; and/or a processor, such as a processor configured to execute instructions stored on and/or provided by a memory coupled to the processor."), comprising: selecting, using at least one processor (“processor”, above), a plurality of fiber pairs (¶ 22, "In various embodiments, network connections between CLSs 121, 123, 125, and/or 127 may be fiber connections including multiple fiber pairs.") from a plurality of cables for routing of at least one transmission ("Additionally, feeder submarine cables 135 and 137 connect offshore switching unit 101 to CLSs 125 and 127, respectively."), the plurality of cables connecting one or more transmission sites ("Additionally, feeder submarine cables 135 and 137 connect offshore switching unit 101 to CLSs 125 and 127, respectively."), the plurality of fiber pairs being selected from different cables in the plurality of cables (¶ 23, "In addition, conventional optical fiber switches may also be used in conjunction with WSS ROADMs for fiber reconfiguration between the fiber pairs of the submarine cables.” N.B., Applicant should please note the use of the plural in “cables”.), and forming a selection group having the plurality of fiber pairs selected from the plurality of cables in accordance with at least one transmission site in the one or more transmission sites (This step actually occurs before the selecting step as the candidate step has to occur before the final selection. Abstract, Fig. 4, ¶¶ 17, 18, "The offshore switching unit is configured to dynamically connect data communication channels of a selected feeder submarine cable among the plurality of feeder submarine cables with data communication channels of the trunk submarine cable.” ¶ 22, "In various embodiments, network connections between CLSs 121, 123, 125, and/or 127 may be fiber connections including multiple fiber pairs."); assigning, using the at least one processor (“processor”, above), using the selection group (per above re the "fiber connections including multiple fiber pairs"), at least one optical transmission path in one or more optical transmission paths to the selected plurality of fiber pairs (¶ 23, "In the event of an optical connection failure, an offshore switch unit is able to re-route the connection including performing wavelength routing using a new data communication channel."); forming, using the at least one processor (“processor”, above), an optical pathway using the selected plurality of fiber pairs and the assigned at least one optical transmission path (¶ 23, "In the event of an optical connection failure, an offshore switch unit is able to re-route the connection including performing wavelength routing using a new data communication channel."); and transmitting, using the at least one processor (“processor”, above), the at least one transmission using the optical pathway between the one or more transmission sites (¶ 23, "In the event of an optical connection failure, an offshore switch unit is able to re-route the connection including performing wavelength routing using a new data communication channel.").

Per claim 1, above. Response to Arguments Applicant's arguments filed September 24, 2025 have been fully considered but they are not persuasive and the claim rejections are not rebutted. Applicant argues that: However, Grubb fails to disclose that "selecting, using at least one processor, a plurality of fiber pairs from a plurality of cables for routing of at least one transmission, the plurality of cables connecting one or more transmission sites, the plurality of fiber pairs being selected from different cables in the plurality of cables, and forming a selection group having the plurality of fiber pairs selected from the plurality of cables in accordance with at least one transmission site in the one or more transmission sites," "assigning, using the at least one processor, using the selection group, at least one optical transmission path in one or more optical transmission paths to the selected plurality of fiber pairs," "forming, using the at least one processor, an optical pathway using the selected plurality of fiber pairs and the assigned at least one optical transmission path," and "transmitting, using the at least one processor, the at least one transmission using the optical pathway between the one or more transmission sites," as recited in claim 1. (Emphasis supplied). Examiner response: Grubb, ¶ 23 states that "In addition, conventional optical fiber switches may also be used in conjunction with WSS ROADMs for fiber reconfiguration between the fiber pairs of the submarine cables.” The rejection to claim 3 cited this text directly. While Applicant cites to ¶ 23 in its arguments, somehow it overlooked this specific reference to reconfiguration not just between fiber pairs of a single submarine cable, but to "reconfiguration between the fiber pairs of the submarine cables". Applicant should please note the use of the plural in “cables” and not the singular “cable”. As such, Grubb does not “inherently” disclose the use of fiber pairs in different cables, but explicitly discloses such use. As such, Grubb is seen to routing through selection of fiber pairs from different cables and not just cable-based routing. As such, the Applicant’s assertions that the rejection based on Grubb is flawed are not seen to withstand scrutiny in light of the actual description in Grubb. Grubb describes routing (and therefore re-routing) based on fiber pairs in different cables. As such, the rejection is not seen as rebutted and the rejection is maintained. Applicant's arguments with regards to the remaining claims all rely upon the arguments set forth above. Consequently, these remaining arguments as seen as being addressed by the examiner's corresponding remarks. Applicant’s remaining arguments fail to comply with 37 CFR 1.111(b) because they amount to a general allegation that the claims define a patentable invention without specifically pointing out how the language of the claims patentably distinguishes them from the references. As such, the examiner makes no remarks regarding them. Conclusion Applicant’s publication US 20240045148 A1 published October 12, 2023 was previously cited. No new art is cited. This is a request for continued examination/RCE of the current application. All claims are drawn to the same invention claimed in the earlier application and could have been finally rejected on the grounds and art of record in the next Office action if they had been entered in the earlier application. Accordingly, THIS ACTION IS MADE FINAL even though it is a first action in this case. See MPEP § 706.07(b). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). If the claims are not drawn to the same invention, they would be subject to restriction and the claims would then not be entered due to restriction by original presentation. A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
