Daily teaches an adapter for a drug mixing and injection system (Fig 9A-B) a valve (fluid valve 210, Fig 9A) comprising a first (Fig 9A) and second position (Fig 9B); the second position (Fig 9B) enabling a second fluid flow between the second opening (opening defined by luer adapter 238) and the outlet port (outlet coupled to needle 34, Fig 9A-B) ([0087]), and blocking the fluid connection to the first opening ([0097]; once rotated from vertical to horizontal position the communication between the vial and the syringe barrel 242 is blocked) Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi with similar valve allowing selective communication as taught by Daily for the purpose of stablishing an isolated fluid communication between the syringe and the vial for in a first position and between the syringe and the and the outlet in a second position to dispense the drug ([0098]). Lavi/Daily are silent wherein the adapter activated position comprising the first and the second subunits are shifted towards each other. Foshee teaches an adapter for a drug mixing and injection system (Fig 1; abstract) comprising a first subunit (upper housing 101, Fig 6b, [0082]) comprising a first opening (opening where container 111 is located, Fig 6D) adapted to hold a vial (container 111 held in the opening, Fig 3b), said vial (111) comprising a pierceable lid (penetrable septum 111a, Fig 3b), and exhibiting a first longitudinal central axis (116, Fig 3), and a second opening (opening where intermediate container 112 is located, Fig 6D) adapted to hold a reservoir (intermediate container 112 held in the second opening, Fig 4B) comprising an injectable liquid (media 113, Fig 4B), and exhibiting a second longitudinal central axis (longitudinal axis of intermediate container 112), wherein the first and the second openings are arranged to hold the vial (111) and the reservoir (112) in a position with the first and the second longitudinal central axes positioned at an angle below 75 (first and second longitudinal axis of opening for vial 111 and reservoir 112 are parallel);a second subunit (lower housing 104, Fig 3B) comprising a valve (vent 117a, including a check valve; [0089]) and an outlet port (conduit opening 124a, Fig 9B) ; at least one internal adapter channel (accessing member 123, Fig 9B) enabling fluid connection between the first opening (opening where container 111 is located, Fig 6D), the second opening (opening where intermediate container 112 is located, Fig 6D), and the outlet port (conduit opening 124a, Fig 9B) (each of the openings houses a container of fluid that is connected to outlet port via accessing members (i.e., 116, 120) and accessing member 123; [0105]); a first cannula (spike 120, Fig 3B) positioned between the valve (117a) and the first opening (opening where container 111 is located, Fig 6D) ([0100]), said first cannula (120) being adapted to pierce the lid (111a) of the vial (111) and to enable fluid connection between the vial (111) and the at least one internal adapter channel (123) ([0100]), and wherein the first (101) and the second subunits (104) are engageable with each other (Fig 7B shows subunits in engagement position), in such a way that the adapter (123) has a resting position in which the first (101) and the second (104) subunits are releasably (Fig 5B) or unreleasably (Fig 7B) connected and the first cannula (120) does not pierce through the lid (111a) of the vial (111) (Fig 5B show position where spike 120 do not pierce the lid of vial 111); Foshee further teaches an activated position (Fig 7B) in which the first (101) and the second (104) subunits are shifted towards each other and are in a position in which the first cannula (120) pierces through the lid (111a) of the vial (111), thereby enabling fluid connection between the vial (111) and the at least one internal adapter channel (123) ([0100]) Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi with similar lower housing coupled to the conduit system having an engagement mechanism with the first subunit; the subunits having a relative movable position as taught by Foshee to improve the efficiency of the activation step and safety of the user by reducing chance of inadvertent puncture ([0100]). Regarding claim 17, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi is silent wherein the adapter comprises guiding means for guiding the first subunit and the second subunit when shifting them towards each other from the resting position into the activated position and/or wherein the first or the second subunit comprise at least one subunit locking means for the engagement of the first subunit with the second subunit Foshee teaches wherein the adapter (100) comprises guiding means (inner surface of upper housing 101, Fig 7B) for guiding the first subunit (101) and the second subunit (104) when shifting them towards each other from the resting position (initial position, Fig 5A-5C) into the activated position (activated position, 6A-6D ) and/or wherein the first or the second subunit comprise at least one subunit locking means for the engagement of the first subunit with the second subunit. Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi/Daily/Foshee with similar guiding surface as taught by Foshee for the purpose of provide alignment for the relative sliding fit of the subunits ([0100]; Fig 7B) Regarding claim 18, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi discloses wherein in the resting position (PAP) the first and the second subunits are unreleasably connected (the first subunit (FS) and second subunit (SS) are unreleasably connected, See Fig 17A), or wherein in the resting position and in the activated position the first and the second subunits are unreleasably connected. Regarding claim 19, Lavi/Daily/Foshee discloses the adapter according to claim 16, wherein the first and the second subunits are adapted such that they can be shifted towards each other single-handedly. Foshee further teaches wherein the first and the second subunits (101,104) are adapted such that they can be shifted towards each other single-handedly ([0100]: “(…) an external force, typically by the hand of a user, is employed to urge the upper housing into the lower housing of the device and subsequently allow the media container accessing spikes to pierce their respective media containers(…)”; Device of Foshee is structurally capable of being actuated to an active position with one hand). Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi/Daily/Foshee with similar lower housing coupled to the conduit system having an engagement mechanism with the first subunit; the subunits having a relative movable position by a force applied by the hand of the user as taught by Foshee to improve the efficiency of the activation step and safety of the user by reducing chance of inadvertent puncture ([0100]) Regarding claim 20, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi discloses wherein the first (1002, Annotated Fig 1) and the second (1004, Annotated Fig 1) longitudinal central axes are positioned at an angle between 50° and 0°, preferably between 20° and 0° (First 1002 and second 1004 longitudinal axes are parallel at an angle of 0°). Regarding claim 21, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi embodiment of Fig 32/17 is silent wherein the first opening is equipped with a vial locking means for unreleasably connecting the vial to the first opening. Lavi embodiment of Fig 20A teaches an adapter (drug delivery system 498, Fig 20A) wherein the first opening (2000, Annotated Fig 2) is equipped with a vial locking means (arms 505 having ridges 507, Fig 20A) for unreleasably connecting the vial to the first opening (Fig 20A) ((Page 31, lines 22-24):“Once inserted, the lip 505 A of a standard vial 500 is locked into position by means of a pair of arms 505 having ridges 507 projecting inwardly therefrom”). PNG media_image2.png 582 856 media_image2.png Greyscale Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi/Daily/Foshee with similar locking means as taught by Lavi embodiment of Fig 20 for the purpose of securing the vial from unintended disconnection (Page 31, lines 22-24). Regarding claim 22, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi is silent wherein the adapter, preferably the second subunit, further comprises at least one dedicated site for resting a finger when bringing the adapter from the resting position into the activated position. Foshee teaches the adapter (100), preferably the second subunit (104), further comprises at least one dedicated site for resting a finger when bringing the adapter from the resting position into the activated position ([0100]: second subunit of adapter of Foshee is structurally capable of performing the claimed function. Adapter can be held with one hand; the thumb can be placed on the lower surface of second subunit 104 while the rest of the fingers are placed on top of the first subunit 101 to exert the hand force). Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi/Daily/Foshee with similar lower housing coupled to the conduit system having an engagement mechanism with the first subunit; the subunits having a relative movable position by a force applied by the hand of the user as taught by Foshee to improve the efficiency of the activation step and safety of the user by reducing chance of inadvertent puncture ([0100]). Regarding claim 23, Lavi/Daily/Foshee discloses the adapter according to claim 16, Lavi discloses wherein the adapter is sterilizable (adapter of Lavi is structurally capable of being sterilized). Regarding claim 24, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi discloses wherein the adapter (760) comprises a second cannula (needle 394, Fig 17A)positioned between the valve and the second opening (See Fig 17A and 32A), said second cannula (394) being adapted to pierce the lid of the reservoir (390) (Fig 17A) and to enable a fluid connection between the reservoir (390) and the at least one internal adapter channel (398). Regarding claim 26, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi discloses wherein the outlet port comprises an injection means, or is adapted for attaching an injection means (outlet port comprises injection needle 731, Fig 32E). Regarding claim 27, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi discloses wherein the adapter (720) is preassembled prior to use (Fig 32B shows adapter 720 assembled prior to use). Claim 25 is rejected under 35 U.S.C. 103 as being unpatentable over Lavi et al. (WO 0172354 A2) in view of Daily et al. (US 20150182699 A1), in further view of Foshee et al. (US 20120089088 A1) in further view of Kraus et al. (US 20070079894 A1). Regarding claim 25, Lavi/Daily/Foshee discloses the adapter according to claim 16. Lavi/Daily/Foshee are silent wherein the first subunit has a gas-permeable and liquid-impermeable filter, said filter being configured to compensate and/or equilibrate pressure. Kraus teaches an adapter comprising a first subunit (covering element 360 + main body element 302, Fig 5) has a gas-permeable and liquid-impermeable filter (membrane 336 and carbon filter 340, Fig 4), said filter being configured to compensate and/or equilibrate pressure ([0177]: sterile air is allowed to pass, which contributes to pressure equilibrium in the system). Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the device of Lavi/Daily/Foshee with similar filter system as taught by Kraus for the purpose of allow free passage of air into the drug mixing system while preventing passage thereinto of liquid and air-borne particles, microorganisms ([0177]). Response to Arguments Applicant's arguments filed 02/25/2026 have been fully considered but they are not persuasive. Applicant submits that claims are non-obvious over the combination of Lavi, Daily, and Foshee because the combination does not teach, suggest, or hint at every element of the claims. Furthermore, the skilled person has no motivation to combine the references because the proposed modification would render the references being modified inoperable for their intended purposes. If a proposed modification would render the reference being modified unsatisfactory for its intended purpose, there is no suggestion or motivation to make the proposed modification. Examiner respectfully disagrees, Lavi discloses all limitations of claim 16. Lavi discloses a first position where communication between the syringe and vial is permitted. The diluent from the syringe is delivered into the vial. However, the device is structurally capable of reconstitution. The forwards and backwards movement of the plunger of the syringe any number of desired cycles permits further reconstitution if desired because the first position of the valve allow communication between the syringe and the vial. Lavi discloses a second position of the valve where there is communication with the outlet. However, as applicant stated, the connection is between the vial and the outlet. Daily teaches an adapter for a drug mixing and injection system (Fig 9A-B) a valve (fluid valve 210, Fig 9A) comprising a first (Fig 9A) and second position (Fig 9B); the second position (Fig 9B) enabling a second fluid flow between the second opening (opening defined by luer adapter 238) and the outlet port (outlet coupled to needle 34, Fig 9A-B) ([0087]), and blocking the fluid connection to the first opening ([0097]; once rotated from vertical to horizontal position the communication between the vial and the syringe barrel 242 is blocked) Daily, as seen above, teaches a valve allowing communication between the vial and the syringe in a first position, also structurally capable of reconstitution by forward and backwards movement of the piston. Daily further teaches a communication between the outlet and the syringe to dispense the medicament. Modification proposed do not indicate a direct replacement of one valve with another, but is intended to maintain the scope of the mechanism of Daily by having a similar valve that allows communication between the syringe and the vial in a first position and allow dispensing of medication in a second position. The modification will allow a communication between the outlet and the syringe in the second position, as taught by Daily. This will permit the user to dispense the medication through the syringe plunger as seen in Daily, [0098] or by the center button of the vial. Alternatively, the button function could be replaced by the syringe plunger to simplify the design and reduce the number of parts. The modification does not alter the intended function of the device, allowing dispensation of the medication. Applicant submits that Foshee does not teach the device to achieve a resting position in which the subunits are engaged but the system is not yet in an activated fluid-transfer state. Examiner respectfully disagrees please see relevant portion below: Foshee teaches that the adapter (123) has a resting position in which the first (101) and the second (104) subunits are releasably (Fig 5B) or unreleasably (Fig 7B) connected and the first cannula (120) does not pierce through the lid (111a) of the vial (111) (Fig 5B show position where spike 120 do not pierce the lid of vial 111); an activated position (Fig 7B) in which the first (101) and the second (104) subunits are shifted towards each other and are in a position in which the first cannula (120) pierces through the lid (111a) of the vial (111), thereby enabling fluid connection between the vial (111) and the at least one internal adapter channel (123) ([0100]) Modification will enhance safety of the user by reducing chance of inadvertent puncture ([0100]). Also, it will allow the user to maintain the vial sealed and sterile when assembled until the user proceed to inject the medication. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
