DETAILED ACTION 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 . Acknowledgment is made of the amendment filed November 26, 2025. The application has been updated accordingly. Claim Objections The objections to claims 10, 13 and 16 have been withdrawn. Claim Rejections - 35 USC § 102 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 (i.e., changing from AIA to pre-AIA ) 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. 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, 4-9 and 13-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wolner et al. (2010/0226748) hereinafter Wolner. Wolner discloses: Claim 1: A lifeline apparatus comprising: a housing (Fig. 3; 101/121) defining an interior portion (Fig. 4; 137) configured for storing at least a portion of a retractable lifeline (Fig. 4; 225) therein; a spool lock assembly (Fig. 4; 145) selectively configurable between a locked configuration (Fig. 10, Para. [0034]) and an unlocked configuration (Fig. 14, Para. [0034]) to facilitate a selective deployment of at least a portion of the retractable lifeline from within the housing (Para.

[0034]). Claim 17: The lifeline apparatus of claim 1, wherein the spool lock assembly further comprises a biasing spring (Fig. 5A; 154) engaged with the lock arm (Fig. 5A; 155b) and configured to apply one or more bias forces to the lock arm to bias a rotation thereof towards the locked position (Para. [0055]). Claim 18: The lifeline apparatus of claim 17, wherein at least a portion of the lock arm is in physical contact with an arm engagement tab provided along an underside of the latch plate (Fig. 10; 155b is depicted as having physical contact with 280) such that a biased configuration of the lock arm causes the latch plate to be biased towards the nominal position (Para. [0055]). Claim 19: The lifeline apparatus of claim 1, wherein the latch plate includes an underside (Fig. 10; see detail) accessible to a user via an opening between the latch plate and the exterior of the housing. Claim 20: The lifeline apparatus of claim 1, wherein the actuated position of the latch plate is defined at least in part by at least a portion of the latch plate protruding outward in a direction at least partially away from an exterior surface of the housing (Fig. 5A; 155b protrudes away from the exterior surface of 101). 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 10-12 are rejected under 35 U.S.C. 103 as being unpatentable over Wolner et al. (2010/0226748) hereinafter Wolner, in view of Kolb (3,517,570). Claim 10: Wolner discloses the lifeline apparatus of claim 6, but fails to disclose further comprising one or more ball plungers configured to facilitate a retention of the latch plate in one or more of the nominal position and the actuated position by engaging a surface of the latch plate to cause an interference between the latch plate and an adjacent surface of a tray of the spool lock assembly that operably resists a rotational movement of the latch plate away from one or more of the nominal position and the actuated position. However, Kolb discloses ball plungers (Fig. 2; 62) and openings (Fig. 2; 76) to receive the ball plungers. Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to modify the latch plate and adjacent surface (146) of Wolner to include the ball plungers and openings, as taught by Kolb, with a reasonable expectation of success because it would facilitate discrete positioning when turning the knob (Col. 3, Lines 10-16). Thus, in combination Wolner and Kolb disclose the one or more ball plungers, of Kolb, to configured to facilitate a retention of the latch plate, of Wolner, in one or more of the nominal position and the actuated position by engaging a surface of the latch plate to cause an interference between the latch plate and an adjacent surface of a tray of the spool lock, modified by Kolb to include openings, assembly that operably resists a rotational movement of the latch plate away from one or more of the nominal position and the actuated position (Kolb - Col. 3, Lines 10-16). Claim 11: Wolner and Kolb disclose the lifeline apparatus of claim 10, wherein the latch plate (Wolner - Fig. 3; 148) defines one or more indentions (Kolb - Fig. 2; 76) provided at respective lateral side surfaces thereof is configured such that, when the latch plate is positioned in one or more of the nominal position and the actuated position, the latch plate is configured to receive at least a portion of the one or more ball plungers (Kolb - Fig. 2; 62) within the one or more indentions, wherein the one or more ball plungers being at least partially disposed within the one or more indentions at least partially secures the latch plate relative to the adjacent surface of the tray to resist a relative movement of the latch plate away from the adjacent surface of the tray (Kolb - Col. 3, Lines 10-16). Claim 12: Wolner and Kolb disclose the lifeline apparatus of claim 11, wherein the one or more ball plungers (Kolb - Fig. 2; 62) comprises a first ball plunger disposed between a first lateral side surface of the latch plate (Wolner - Fig. 5A; 148, once modified by Kolb Fig. 2; 62 right) and a first lateral side surface of the tray adjacent thereto (Wolner - Fig. 5A; 146, once modified by Kolb Fig. 2; 76 right), and a second ball plunger disposed between an opposing second lateral side surface of the latch plate (Wolner - Fig. 5A; 148, once modified by Kolb Fig. 2; 62 left) and a second lateral side surface of the tray adjacent thereto (Wolner - Fig. 5A; 146, once modified by Kolb Fig. 2; 76 left), wherein the one or more indentions defined by the latch plate comprises a first indention provided along the first lateral side surface and configured to receive at least a portion of the first ball plunger therein when the latch plate is positioned in the actuated position, and a second indention provided along the second lateral side surface and configured to receive at least a portion of the second ball plunger therein when the latch plate is positioned in the actuated position (Kolb - Col. 3, Lines 10-16). Allowable Subject Matter Claims 2-3 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claim 2 is considered allowable due to the recitation of the latch plate being hingedly connected to a latch pin. Claim 3 is considered allowable due its dependency from claim 2. Response to Arguments Applicant’s arguments with respect to claims 1 and 4-5 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant's arguments filed November 26, 2025 have been fully considered but they are not persuasive. With respect to the prior art rejections, applicant argues that the primary reference of Wolner fails to disclose a latch plate movable from a nominal position to an actuated position by pulling at least at portion of the latch plate outward from the exterior of the housing. This argument is not persuasive because Fig. 10 depicts feature 148 as closer to 146 where the outer perimeter of 148 are seated in a groove of 146 and Fig. 14 depicts feature 148 with that same outer perimeter as separated from the groove of 146. Moreover, Para. [0059] describes another embodiment where a tool can be used to move 148 and pull it outward, indicating that the function of 148 is to move inward and outward in addition to rotating. For at least these reasons applicants remarks are not found persuasive and the claims remain rejected as advanced above. 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.
