Office Action

§102 §103 §112
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 . Response to Amendment Applicant’s amendments filed 25th February 2026 have been entered. Claims 1-20 are pending. Response to Arguments Applicant's arguments filed 25th February 2026 have been fully considered but they are not persuasive. Applicant’s arguments with regard to the prior art rejections are as follows: Applicant argues ‘Rao describes something entirely different than the amended claimed subject matter.’, Applicant provides amended claim language with item callouts. Applicant continues for clarification: ‘the sensor assembly is detachably coupled to the insertion device while the electronics assembly is located on the base. This is entirely different than what is described in Rao. For example, in Figs. 3A – 3G of Rao the sensor tray 810 contains the sensor assembly which is completely separate from the applicator 150. As shown in Figs. 3C-3E of Rao, the sensor becomes loaded with the applicator only after the applicator moved between it’s first and second positions. Applicants submit this is completely different than the amended claimed subject matter that includes an insertion device in a first position containing a slider to which a sensor assembly is detachably coupled.‘. Examiner respectfully disagrees with Applicant. With the amended subject matter changing the scope with clarifying structure. Examiner has included updated mapping to the citations provided in response to the clarifying structure within the amended subject matter regarding the arguments pertaining to claim 1: Rao discloses an insertion device (item 4150) containing a slider in a first position (Rao: item 4606 & item 4604 combined; Para. [0160] & Fig. 19A) and a sensor assembly detached from the electronics assembly (Rao: Para. [0147], [0219]; Para. [0158]; Note: by default, the sensor control device 102 is detached from the electronics assembly, but is capable of being removably coupled with it via Para. [0147] ‘At Step 1105, a sensor control device 102 is loaded into the applicator 150.’ & Para. [0098].) wherein the sensor assembly includes a sensor and at least one mating feature (Rao: Para. [0147]), the sensor assembly detachably couple to the slider in a first position (Rao: Para. [0147], [0219]; Para. [0158]; Note: by default, the sensor control device 102 is detached from the electronics assembly, but is capable of being removably coupled with it via Para. [0147] ‘At Step 1105, a sensor control device 102 is loaded into the applicator 150.’ & Para. [0098].) (updated citations added). The citations map to the structural requirements of the claims and thus meet the claim limitations, there are currently no amendments that result in a structural difference or inventive concept over the prior art of record. Specification The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Objections Claim 1 is objected to because of the following informalities: Claim 1 recites ‘an insertion device containing a slider in a first position and a sensor assembly detached from the electronics assembly wherein the sensor assembly includes a sensor and at least one mating feature’, Examiner suggesting amending this limitation to read ‘an insertion device containing a slider in a first position and a sensor assembly detached from the electronics assembly, wherein the sensor assembly includes a sensor and at least one mating feature’. Appropriate correction is required. 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. Claims 1-20 are 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 1 ‘detachably coupled to the slider in a first position’, it is unclear if this is referring to ‘a first position’, as previously recited or not, rendering claim 1 indefinite. Examiner interprets this limitation to intend ‘the first position’. Claim 18, ‘wherein the vent is formed in a receiver portion’, it is unclear if this is referring to ‘a receiver portion’ as previously recited in claim 1, rendering claim 18 indefinite. Examiner interprets this limitation to intend ‘the receiver portion’. Claims 2-20 are rejected by virtue of their dependence on a rejected parent claim. 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. Claim(s) 1-17, 19-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 20200196919 A1 to Rao et al. (hereinafter, Rao) Regarding Claim 1, Rao discloses an insertion assembly (Rao: Abstract), comprising: an electronics assembly being supported by a stand (Rao: item 4704 sheath), the electronics assembly including a base and a housing (Rao: Para. [0093] ‘the sensor applicator 150 contains an electronics housing (not shown) that retains the electrical components’ item 4702; Para. [0157] ‘sensor electronics carrier 4710’; Fig. 18A item 4710), the housing having an enclosed portion and a receiver portion (Rao: Para. [0169] bottom portion of applicator 4150 where the applicator deploys the sensor control device to the skin is interpreted to be the receiver portion. The enclosed portion is the portion of the housing that appears to enclose); an insertion device (item 4150) containing a slider in a first position (Rao: item 4606 & item 4604 combined; Para. [0160] & Fig. 19A) and a sensor assembly detached from the electronics assembly (Rao: Para. [0147], [0219]; Para. [0158]; Note: by default, the sensor control device 102 is detached from the electronics assembly, but is capable of being removably coupled with it via Para. [0147] ‘At Step 1105, a sensor control device 102 is loaded into the applicator 150.’ & Para. [0098].) wherein the sensor assembly includes a sensor and at least one mating feature (Rao: Para. [0147] ), the sensor assembly detachably coupled to the slider in a first position (Rao: Para. [0147], [0219]; Para. [0158]; Note: by default, the sensor control device 102 is detached from the housing, but is capable of being removably coupled with it via Para. [0147] ‘At Step 1105, a sensor control device 102 is loaded into the applicator 150.’ & Para. [0098]; Note: the sensor control device is loaded into the applicator with the slider in an initial position, where the slider is coupled with the carrier for the control device and thus coupled to the sensor assembly when loaded, then upon activation the slider is transitioned to an unloaded position driving the sensor control device to the base of the sheath/applicator to the target location of skin for in vivo analyte sensing.), wherein the slider is coupled to an energy storage system (Rao: Para. [0111], [0114], [0160] ‘drive spring… retraction spring… each in a preloaded state… a first end coupled to firing pin… and a second end coupled to sensor electronics carrier’); wherein the slider is further configured to transition to a second position that couples the sensor assembly to the receiver portion to define an on-body assembly (Rao: Para. [0084]; Rao: Para. [0147], [0219]; Para. [0158]; Note: by default, the sensor control device 102 is detached from the housing, but is capable of being removably coupled with it via Para. [0147] ‘At Step 1105, a sensor control device 102 is loaded into the applicator 150.’ & Para. [0098]; Note: the sensor control device is loaded into the applicator with the slider in an initial position, where the slider is coupled with the carrier for the control device and thus coupled to the sensor assembly when loaded, then upon activation the slider is transitioned to an unloaded position driving the sensor control device to the base of the sheath/applicator to the target location of skin for in vivo analyte sensing), the transition to the second position loads the energy storage system and upon actuation, the energy storage system is unloaded to transition the slider to the first position (Rao: Rao: Para. [0147], [0219]; Para. [0158]; Note: by default, the sensor control device 102 is detached from the housing, but is capable of being removably coupled with it via Para. [0147] ‘At Step 1105, a sensor control device 102 is loaded into the applicator 150.’ & Para. [0098]; Para. [0168]; Para. [0170] ‘As retraction spring 4604 expands in a proximal direction, sharp carrier 4602 is displaced to the third position within applicator 4150 (e.g., top of sheath 4704), which causes the sharp to withdraw from the skin surface.’; Para. [0244]; Note: the sensor control device is loaded into the applicator with the slider in an initial position, where the slider is coupled with the carrier for the control device and thus coupled to the sensor assembly when loaded, then upon activation the slider is transitioned to an unloaded position driving the sensor control device to the base of the sheath/applicator to the target location of skin for in vivo analyte sensing, then the slider retraction processes) and the on-body assembly is positioned to decouple from the slider (Rao: Para. [0098]). Regarding Claim 2, Rao discloses the insertion assembly as described in claim 1, Rao further discloses comprising: a slider engagement coupled with the slider (Rao: Para. [0244]); a sharp configured to be coupled with the slider (Rao: Para. [0125] ‘sensor electronics carrier 710 that can retain sensor electronics within applicator 150. It can also retain sharp carrier 1102 with sharp module 2500’; Para. [0160] ‘Drive spring 4606 includes a first end coupled to firing pin 4705 and a second end coupled to sensor electronics carrier 4710.’); and a patch coupled to the base, the patch having a skin-side adhesive configured to couple the on-body assembly to a subject (Rao: Para. [0098] ‘The adhesive patch 105 (FIG. 1) applied to the bottom of sensor control device 102 adheres to the skin to secure the sensor control device 102 in place.’). Regarding Claim 3, Rao discloses the insertion assembly as described in claim 2, Rao further discloses wherein a first coupling force between the skin-side adhesive and the subject is greater than a second coupling force between the on-body assembly and the slider (Rao: Para. [0126] ‘The adhesive force retains sensor control device 102 on the skin and overcomes the lateral force applied by spring arms 1518. As a result, spring arms 1518 deflect radially outwardly and disengage detents 1519 from sensor control device 102 thereby releasing sensor control device 102 from applicator 150.’; Para. [0158]). Regarding Claim 4, Rao discloses the insertion assembly as described in claim 1, Rao further discloses wherein the electronics assembly further includes electrical circuitry along with a power supply being contained within the enclosed portion (Rao: Para.

Claim Rejections - 35 USC § 103 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 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. Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over US 20200196919 A1 to Rao et al. (hereinafter, Rao) in view of US 20180353117 A1 to Bullington et al. (hereinafter, Bullington). Regarding Claim 18, Rao discloses The insertion assembly as described in claim 17, Rao does not explicitly disclose wherein the electronics assembly includes a vent being formed in a receiver portion. However, Bullington teaches wherein the electronics assembly includes a vent, wherein the vent is formed in a receiver portion (Bullington: Para. [0091]). One of ordinary skill in the art at the time the invention was filed would have found it obvious to modify the electronics assembly of Rao to include a vent as taught by Bullington to allow gas to vent from the assembly (Para. [0091] ‘the vent material 242 can be a self-sealing material configured to selectively allow a flow of gas (e.g., air) to vent from the sequestration portion 234 through the opening 235.’). 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.
