Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 3, 7, and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Allen in view of Montgelas et al. (US 2015/0362691 A1, herein Montgelas”). Regarding claim 3, Allen discloses the invention of claim 2, but Allen does not teach the securing portion comprises a T-slot. Montgelas teaches a base (plate 26) having tabs (422) defined by T-shaped portions for detachably securing optical cables with hook loop straps or the like (Para [0166] and Fig. 29). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to recognize the T-shaped tabs can be punched into the base of Allen’s cable management device for securing optical cables as taught by Montgelas. One would be motivated to use T-shape tabs for securing optical cables so that the cables can be secured and/or easily removable for readjustments. Regarding claim 7, Allen discloses the invention of claim 4, however, Allen does not disclose the fiber storage portion comprises a fiber spool. Montgelas teaches a spool (475) is provided on base plate (28) for organizing optical cables (Fig. 46). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to recognize the Allen’s modular splice tray can be modified to support a spool on the base (102) to organize the optical cables. One would be motivated to provide a spool to organize the cables while preventing the optical fiber from damage. Regarding claim 14, Allen discloses the invention of claim 12, but Allen does not teach the securing portion comprises as a T-slot. Montgelas teaches a base (plate 26) having tabs (422) defined by T-shaped portions for detachably securing optical cables with hook loop straps or the like (Para [0166] and Fig. 29). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to recognize the T-shaped tabs can be punched into the base of Allen’s cable management device for securing optical cables as taught by Montgelas. One would be motivated to use T-shape tabs for securing optical cables so that the cables can be secured and/or easily removable for readjustments. Response to Arguments Applicant's arguments filed on December 29, 2025 have been fully considered but they are not persuasive. Applicant’s main argument is with respect to the anticipatory rejection over Allen does not disclose the amended limitations of independent claims 1, 12, and 20. And the rejection of claims 3, 7, and 14 over Allen in view of Montgelas do not correct the deficiencies of the amended independent claims. The examiner addressed each and every limitations to all of the amended claims 1-8, 10-16, 18-20, and 22-24, including new claim 25 in the rejections above. In summary, the original rejection teaches the edge connecting portions removably connect to an edge connection portion of an other device are two identical splice trays are edge coupled to modularly expand the cable management system. The amended claims distinguished the “an other device” to be a device that is not identical to the cable management device. The frame portion 121 with receiving portions 120 function as the recited “an other device” that is not identical to the cable management device (splice tray 100). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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. 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 nonprovisional extension fee (37 CFR 1.17(a)) 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. For these reasons, the examiner finds applicant arguments of prior arts to Allen and Montgelas failing to the teach the amended claims to be not persuasive.
