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 . This action is in response to Applicant’s election filed on July 7th, 2026. Claims 18-20 are withdrawn. Election/Restrictions Applicant’s election without traverse of Claims 1-17 in the reply filed on July 7th, 2026 is acknowledged. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(1) because they are unclear/poor quality with low resolution. Corrected drawing sheets in compliance with 37 CFR 1.121(d), or amendment to the specification to add the reference character(s) in the description in compliance with 37 CFR 1.121(b) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. In addition to Replacement Sheets containing the corrected drawing figure(s), applicant is required to submit a marked-up copy of each Replacement Sheet including annotations indicating the changes made to the previous version. The marked-up copy must be clearly labeled as “Annotated Sheets” and must be presented in the amendment or remarks section that explains the change(s) to the drawings. See 37 CFR 1.121(d)(1). Failure to timely submit the proposed drawing and marked-up copy will result in the abandonment of the application. 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. Claims 11-17 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 11 recites “a user-wearable infusion pump” on line 4 rending the claim indefinite because it is unclear whether it is referring to the same user-wearable infusion pump introduced in the preamble on line 1. Claims 13-15 similarly recite “a user-wearable infusion pump” and Examiner recommends amending the claims to recite “the user-wearable infusion pump”. Appropriate action is required. All remaining claims are rejected by virtue of dependency on the rejected independent claim. 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.

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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 3-6 and 13-14 are rejected under 35 U.S.C. 103 as being unpatentable over Cook. Regarding claim 3, the embodiments of Cook as depicted in Figs.1A-2F disclose the user-wearable infusion pump system (patch pump 100, 200 – Fig.1A) of claim 1, as recited above. The embodiments do not appear to expressly disclose wherein the pump retention features comprising a rigid material include one or more guide rails extending upwardly from the frame base interior of the outer perimeter of the frame base. However, the embodiments of Cook as depicted in Figs.4A-4F disclose wherein the pump retention features comprising a rigid material include one or more guide rails (rail 407 – Fig.4A) extending upwardly from the frame base interior of the outer perimeter of the frame base. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the embodiments depicted in Figs.1A-2F with the embodiments depicted in Figs.4A-4F to disclose the pump retention feature comprising one or more guide rails (“the embodiments herein are specifically described…singly or in combination with one another”, see para [0035]). Regarding claim 4, the embodiments of Cook as depicted in Figs.1A-2F disclose the user-wearable infusion pump system (patch pump 100, 200 – Fig.1A) of claim 3, as recited above. The embodiments do not appear to expressly disclose wherein the one or more guide rails are configured to interface with a corresponding recess on the user-wearable infusion pump to aid in proper alignment of the user-wearable infusion pump on the pump holder. However, the embodiments of Cook as depicted in Figs.4A-4F disclose wherein the one or more guide rails are configured to interface with a corresponding recess on the user-wearable infusion pump to aid in proper alignment of the user-wearable infusion pump on the pump holder (“rail 407 terminates at the sealing membrane 412 to properly align the pump 402 with the sealing membrane 412. As can be seen in FIG. 4F, both the cartridge 416 and the drive unit 418 can include slots 417, 419 that mate with rail 407”, see para [0028]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the embodiments depicted in Figs.1A-2F with the embodiments depicted in Figs.4A-4F so that the guide rails are configured to interface with a corresponding recess on the user-wearable infusion pump (“the embodiments herein are specifically described…singly or in combination with one another”, see para [0035]).

However, the embodiments of Cook as depicted in Figs.8A-8F disclose wherein the pump retention features comprising a rigid material include a locking projection (snap portion 815 – Fig.8A) extending upwardly from the outer perimeter of the frame base. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the embodiments depicted in Figs.1A-2F with the embodiments depicted in Figs.8A-8F to disclose the pump retention feature comprising a locking projection (“the embodiments herein are specifically described…singly or in combination with one another”, see para [0035]). Regarding claim 6, the embodiments of Cook as depicted in Figs.1A-2F disclose the user-wearable infusion pump system (patch pump 100 – Fig.1A) of claim 1, as recited above. The embodiments do not appear to expressly disclose, wherein the locking projection is configured to interface with a switch on the user-wearable infusion pump that can slide between locked and unlocked positions to releasably lock the user-wearable infusion pump on the pump holder. However, the embodiments of Cook as depicted in Figs.8A-8F disclose wherein the locking projection (snap portion 815 – Fig.8A) is configured to interface with a switch on the user-wearable infusion pump that can slide between locked and unlocked positions to releasably lock the user-wearable infusion pump on the pump holder (“the snap portion 815 is initially pushed away from the pump 802 and then snaps into place when aligned with the recess 839 to cause an audible clicking or snapping sound that provides an indication to the user that the pump 802 is properly mated to the attachment portion 806”, see para [0032], Fig.8E). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the embodiments depicted in Figs.1A-2F with the embodiments depicted in Figs.8A-8F to disclose the pump retention feature comprising a locking projection configured to interface with a switch on a user-wearable infusion pump that can slide between locked and unlocked positions (“the embodiments herein are specifically described…singly or in combination with one another”, see para [0035]). Regarding claim 13, the embodiments of Cook as depicted in Figs.1A-2F disclose the user-wearable infusion pump system (patch pump 100, 200 – Fig.1A) of claim 11, as recited above. The embodiments do not appear to expressly disclose wherein the pump retention features comprising a rigid material include one or more guide rails extending upwardly from the frame base interior of the outer perimeter of the frame base, the one or more guide rails configured to interface with a corresponding recess on a user-wearable infusion pump to aid in proper alignment of the user- wearable infusion pump on the pump holder. However, the embodiments of Cook as depicted in Figs.4A-4F disclose wherein the pump retention features comprising a rigid material include one or more guide rails (rail 407 – Fig.4A) extending upwardly from the frame base interior of the outer perimeter of the frame base (“retention frame 406 can be provided with tabs that mate with recesses in pump 402, similar to any of the previous embodiments”, see para [0028], Fig.1A), the one or more guide rails configured to interface with a corresponding recess on a user-wearable infusion pump to aid in proper alignment of the user- wearable infusion pump on the pump holder (“rail 407 terminates at the sealing membrane 412 to properly align the pump 402 with the sealing membrane 412. As can be seen in FIG. 4F, both the cartridge 416 and the drive unit 418 can include slots 417, 419 that mate with rail 407”, see para [0028]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the embodiments depicted in Figs.1A-2F with the embodiments depicted in Figs.4A-4F to disclose the pump retention feature comprising one or more guide rails configured to interface with a corresponding recess on a user-wearable infusion pump (“the embodiments herein are specifically described…singly or in combination with one another”, see para [0035]). Regarding claim 14, the embodiments of Cook as depicted in Figs.1A-2F disclose the user-wearable infusion pump system (patch pump 100 – Fig.1A) of claim 1, as recited above. The embodiments do not appear to expressly disclose wherein the pump retention features comprising a rigid material include a locking projection extending upwardly from the outer perimeter of the frame base, the locking projection configured to interface with a switch on a user-wearable infusion pump that can slide between locked and unlocked positions to releasably lock the user- wearable infusion pump on the pump holder. However, the embodiments of Cook as depicted in Figs.8A-8F disclose wherein the pump retention features comprising a rigid material include a locking projection (snap portion 815 – Fig.8A) extending upwardly from the outer perimeter of the frame base, the locking projection configured to interface with a switch on a user-wearable infusion pump that can slide between locked and unlocked positions to releasably lock the user- wearable infusion pump on the pump holder (the snap portion 815 is initially pushed away from the pump 802 and then snaps into place when aligned with the recess 839 to cause an audible clicking or snapping sound that provides an indication to the user that the pump 802 is properly mated to the attachment portion 806”, see para [0032], Fig.8E). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the embodiments depicted in Figs.1A-2F with the embodiments depicted in Figs.8A-8F to disclose the pump retention feature comprising a locking projection configured to interface with a switch on a user-wearable infusion pump that can slide between locked and unlocked positions (“the embodiments herein are specifically described…singly or in combination with one another”, see para [0035]). Claims 10 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Cook in view of Moberg et al. (US 20080097381 A1, herein. Moberg). Regarding claim 10, Cook discloses the user-wearable infusion pump (patch pump 100 – Fig.1A) of claim 1, as recited above. Cook does not appear to expressly disclose wherein the flexible material is selected from the set consisting of silicone, thermoplastic elastomer and thermoplastic polyurethane.
