Claim 28 is rejected under 35 U.S.C. 103 as being unpatentable over Yairi (US 20090259176 A1) in view of Coffee (US 6318640 B1). Regarding claim 28, Yairi discloses a medicament delivery device (Fig 5A-5B) comprising: a delivery assembly ([0057]) comprising a plurality of microneedles (Claim 16) configured to transdermally deliver medicament to a patient (drugs or agents; abstract), and a system (fluid detector 510; Fig 5A-5B) configured to provide information about a volume (volume of fluid; [0058]) of the medicament (drug delivery; [0008]) in the medicament delivery device (Fig 5A-5B), the system comprising: a sensing unit (fluid detector 510; Fig 5A-5B) configured to measure at least one physical parameter (resistivity; [0058]) dependent on the volume of the medicament in the medicament delivery device (presence of fluid or air within at least one of the microchannels 506; whether reservoir 501 is empty; and/or the resistivity between the electrodes, [0058]), wherein the sensing unit (510) comprises: a first electrode (1000, Annotated Fig 1), and a second electrode (1001, Annotated Fig 1). Yairi is silent wherein at least one of the first and second electrodes is permeable to a medicament. Coffee teaches medicament delivery device (pump; Fig 7) comprising a porous membrane (volume of powder silica 9 inside tube 7a, Fig 7); a first electrode (electrode 8a, Fig 7) and a second electrode (electrode 8b, Fig 7), wherein at least one of the first and second electrodes is permeable to a medicament (Col 8 lines 16-38). Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Yairi with similar permeable electrodes in contact with the fluid as taught by Coffee for the purpose of adjust the passage of liquid at a desired flow rate (Col 6, lines 59-63)(Col 8 lines 16-38) . Response to Arguments Applicant's arguments filed 02/24/2026 have been fully considered but they are not persuasive. Applicant submits: A. Neither of Cohen nor Yairi, alone or in combination discloses a fluid flowing between the first and second electrodes flows in a direction from the first electrode and towards the second electrode. B. The plates taught by Cohen function in a different way than the metallic surfaces of Yairi. C. It is unclear whether the conductive plates of Cohen are physically suitable for use with the microchannel Yairi due to size. Examiner respectfully disagrees. A. Cohen discloses the fluid 14 flowing in the direction shown in Annotated Fig 3. The fluid is flowing between first plate 10 and second plate 12 as shown in Annotated Fig 3 below. PNG media_image2.png 362 643 media_image2.png Greyscale Cohen teaches a system (Fig 1) comprising a fluid (fluid 14, Fig 1) flowing between the first (plate 10, Fig 1) and second (plate 12, Fig 1) electrodes flows in a direction (2000, Annotated Fig 3 above) from the first electrode (10) and towards the second electrode (12). As bag 13 empties, fluid 14 inside the bag 13 flows in the direction 2000, Annotated Fig 3. B. Both the plates of Cohen (Col 5, lines 3-15) and Yairi are ([0059]: “to detect the presence of fluid or air within at least one of the microchannels 506”) are capable of detecting fluid. The plates of Cohen are not required to exhibit all the functions of the plates of Yairi such as detection of air. They are analogous art since they both address detecting the presence of fluid. C. Applicant argues that the difference between the plates of Cohen and Yairi differ significantly in size. However the rejection relies in the position of the plates of Cohen to detect the presence of fluid 14, not for its specific dimensions. The implementation of the teaching is not limited by scale and its adaptation to the primary reference is within the ordinary skill in the art. Regarding Claim 28, applicant submits that one of ordinary skill in the art would not have been motivated to modify the metallic surfaces so that they are permeable to medicament in view of the teachings of Coffee (or another reference). Examiner respectfully disagrees. Yairi discloses all limitation of claim 28 except: “(…)wherein at least one of the first and second electrodes is permeable to a medicament.”. Teaching of Coffee would provide the benefit of adjusting the passage of liquid to a desired flow rate (Col 6, lines 59-63)(Col 8 lines 16-38). Yairi/Coffee as modified would exhibit the measuring function of Yairi and the incorporated teaching of Coffee. Conclusion THIS ACTION IS MADE FINAL. 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.
