Office Action

§103
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 . In light of the amendments to the claims filed 10/02/2025 in which claims 17-18, 23, 25, and 32 were amended, claims 17-32 are pending in the instant application and in light of the restriction requirement, claims 17-18, 21-26, and 30-32 are examined on the merits herein. Priority The instant application is a 371 of PCT/IB2021/050484 filed 01/22/2021 which claims priority to IT/102020000002170 filed 02/04/2020 and IT/102020000001387 filed 01/24/2020. Claims 17-32 receive priority to the prior-filed application, filed on 01/24/2020. Response to Arguments Objections to the Claims The objections to the claims are withdrawn in view of the amendments to the claims filed 10/02/2025. Rejections of the Claims under 35 U.S.C. 112(b) The rejections of the claims under 35 U.S.C. 112(b) are withdrawn in view of the amendments to the claims filed 10/02/2025. Rejections of the Claims under 35 U.S.C. 103 Applicant’s arguments, see pg. 8-12, filed 10/02/2025, with respect to the rejection(s) of claim(s) 17 under 35 U.S.C. 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Gargione and Kopfer as evidenced by Fisher as explained below. 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 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. 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. PNG media_image1.png 632 415 media_image1.png Greyscale Ex. Fig. 1 of Gargione Fig. 5A-5B PNG media_image2.png 514 600 media_image2.png Greyscale Ex. Fig. 2 of Kopfer Fig. 4-5 Claims 17-18, 21-26, and 30-32 are rejected under 35 U.S.C. 103 as being unpatentable over WO/02085429 A2 to Gargione in view of U.S. Patent no. 5,584,819 A to Kopfer as evidenced by US/2004/0049162 A1 to Fisher. Regarding claim 17, Gargione discloses a dosing syringe (Fig. 2B, syringe assembly 10) comprising: a hollow cylindrical body (Fig. 1, hollow cylindrical body 12) and a plunger configured to slide within the hollow cylindrical body (Fig. 1, elongated plunger 22; pg. 7 ln. 12-22), the hollow cylindrical body comprising a main body and a proximal end provided with an aperture (Ex. Fig. 1 showing main body and proximal end provided with aperture 20); wherein the proximal end is removable and blocked between a side surface of the adapter and a bottom wall provided with an aperture of the adapter (pg. 7 ln. 2-11 and 19-22 and pg. 8 ln. 1-3; Ex. Fig. 1 showing proximal end snugly seated in interior wall 44 of adaptor 30 and triangular shaped leaves 60 sealed about central aperture 56 of adaptor 30), the aperture of the proximal end and the aperture of the bottom wall being in direct fluid communication therebetween (Ex. Fig. 1 showing aperture 20 of the proximal end in direct fluid communication with central aperture 56 comprising leaves 60). Gargione differs from the instantly claimed invention in that Gargione fails to disclose the main body that has at least one portion having a cross-section smaller than that of the proximal end, wherein a surface is delimited between the main body and the proximal end, which is configured to abut against a corresponding surface of an adaptor. Kopfer teaches a connector for a syringe that has at least one portion having a cross-section smaller than that of the proximal end (Ex. Fig. 2 showing main body of needle hub 11 having groove 14 smaller than some sections of the proximal end of needle hub 11), wherein a surface is delimited between the main body and the proximal end, which is configured to abut against a corresponding surface of an adaptor (Ex. Fig. 2 showing abutment surface configured to abut against annular rim 24/24’ on adaptor 20), so that the proximal end is removable (col. 4 ln. 8-12). It would be considered obvious to one of ordinary skill in the art before the effective filing date of the instant application to modify the main body and adaptor of Gargione to comprise the connection means as taught by Kopfer, because Kopfer teaches that this provides for a releasable, locked engagement (col. 3 ln. 64-67 and col. 4 ln. 1-12), which would provide further security to the friction-fit connection of Gargione’s syringe and adaptor when filling the syringe. Fisher provides evidence that a luer slip adaptor, such as that of Gargione, could be improved upon as it allows for motion and loosening between the syringe and the device (para. 0004) and can leak fluid if improperly seated (para. 0007). In the modification of Gargione with Kopfer, the dosing syringe of Gargione would comprise all of the connection mechanisms of the body of the connector of the syringe as taught by Kopfer and the adaptor of Gargione would comprise all of the connection mechanisms of the adaptor as taught by Kopfer; therefore, the groove (14) of Kopfer would be considered the portion of the main body of Gargione that has a smaller cross-section than the proximal end, the abutment surface (Ex. Fig. 2) of Kopfer would be considered the surface of Gargione that is delimited between the main body and proximal end, and the annular tooth (24/24’) of Kopfer would be considered the corresponding surface of the adaptor of Gargione. Regarding claim 18, the cited prior art suggests the invention of claim 17. Gargione further discloses wherein said proximal end is hemispherical (Ex. Fig. 1 showing proximal end as generally hemispherical). Kopfer teaches (as noted in the rejection of claim 17) wherein said main body comprises at least one groove formed on an external surface of the main body that extends along a perimeter length of the main body immediately above said abutment surface and at an end of the major axis of the cross-section of the main body (col. 3 ln. 64-67 and col. 4 ln. 1-12; Ex. Fig. 2 showing main body of needle hub 11 having groove 14 extending along perimeter of main body immediately above abutment surface and around the cross-section of the main body). The prior art differ from the instantly claimed invention in that they fail to disclose wherein the main body has an elliptical cross-section. It would have been an obvious matter of design choice to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the main body to define an elliptical cross-section, since a modification would have involved a mere change in the form or shape of a component. A change in form or shape is generally recognized as being within the level of ordinary skill in the art. In re Dailey, 149 USPQ47 (CCPA 1976). In the device as modified, the main body of the syringe would have an elliptical cross-section. Regarding claim 21, the cited prior art suggests the invention of claim 17. Kopfer teaches (as noted in the rejection of claim 17) wherein said surface between the main body and the proximal end, for abutment against the adapter, is orthogonal or inclined with respect to a longitudinal axis of main body (Ex. Fig. 2 showing abutment surface inclined to a longitudinal axis of the main body of needle hub 11). Regarding claim 22, the combination of Gargione and Kopfer suggests the invention of claim 18; however, the prior art differ from the instantly claimed invention in that they fail to disclose wherein said at least one groove comprises two grooves, each of the grooves extending at a respective end of the major axis of the elliptical cross-section of the main body. It would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application to have duplicated the groove to comprise two grooves since it has been held that mere duplication of the essential working parts of a device involves only routine skill in the art. Furthermore, the court held that mere duplication of parts has no patentable significance unless a new and unexpected result is produced. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). See MPEP 2144. Regarding claim 23, the cited prior art suggests the invention of claim 17. Gargione further discloses: an adapter for use with the dosing syringe according to claim 17 (Fig. 4A, vial insert 30 as an adaptor; Fig. 5A-B showing syringe assembly 10 in use with adaptor 30), comprising a hollow cylindrical body (Fig. 5B, cylindrical body 32 of adaptor 30) and a flange extending from the hollow cylindrical body (Fig. 5B, flange 34 extending from cylindrical body 32); wherein the hollow cylindrical body comprises a bottom wall including an aperture configured to abut against the hemispherical proximal end of the dosing syringe (Fig. 5B, cylindrical body 32 comprising bottom wall 54 including aperture 56 comprising leaves 60 configured to abut against proximal end of syringe assembly 10), and the proximal end of the hollow cylindrical body contacting adaptor above the bottom wall (Fig. 5A-B showing proximal end of hollow cylindrical body in contact with adaptor 30 above bottom wall 54). Kopfer teaches (as noted in the rejection of claim 17 above) an annular tooth extending internally to an adaptor body which delimits an annular surface configured to abut against the abutment surface of the main body (Ex. Fig. 2 showing annular tooth 24/24’ extending internally delimiting an annular surface that abuts against abutment surface). Regarding claim 24, the cited prior art suggests the invention of claim 23. Kopfer teaches (as noted in the rejection of claim 17 above) wherein said annular tooth is complementary to that of at least one groove formed in the hollow cylindrical body of the dosing syringe (Ex. Fig. 2 showing annular tooth 24/24’ has shape complementary to groove 14). Regarding claim 25, the cited prior art suggests the invention of claim 23. Gargione further discloses: wherein said aperture has a diameter different from the diameter of the aperture of the proximal end of the dosing syringe (Fig. 5B showing central aperture 56 having a different size than that of discharge opening 20; Fig. 5B showing triangular shaped leaves 60 covering central aperture 56 allowing for different sized opening based on pressure put on triangular shaped leaves 60) and is coaxial and in direct fluid communication with the aperture of the proximal end of the dosing syringe (Fig. 5B showing central aperture 56 coaxial with and in direct fluid communication with discharge opening 20), and wherein the dosing syringe is coupled to the adapter (Fig. 5A showing coupled engagement between 10 syringe assembly and 30 adaptor). Regarding claim 26, the cited prior art suggests the invention of claim 23. The combination of the art further suggests wherein the distance between the aperture of the bottom wall and the annular surface of the annular tooth is smaller than the distance between the aperture of the proximal end and the abutment surface of the dosing syringe as the aperture of the proximal end of the syringe (20) passes through the central aperture (56) of the bottom wall of the adaptor of Gargione such that the proximal end aperture is below the central aperture and the abutment surface (Ex. Fig. 2) and annular surface of the annular tooth (Ex. Fig. 2) of Kopfer are in direct overlapping connection. Regarding claim 30, the cited prior art suggests the invention of claim 23. Gargione further discloses: wherein said bottom wall is arched upwards, so that when the dosing syringe is coupled to the adapter, an interspace is delimited between the proximal end and the bottom wall (Ex. Fig. 1 showing 54 bottom wall flared upwards to delimit a space between the proximal end and 54 bottom wall when 10 syringe assembly and 30 adaptor are in coupling arrangement). Regarding claim 31, the cited prior art suggests the invention of claim 23. Kopfer teaches (as noted in the rejection of claim 17 above) wherein the annular surface of the annular tooth is orthogonal or inclined with respect to a longitudinal axis of the adapter (Ex. Fig. 2 showing annular surface of annular tooth 24/24’ inclined to longitudinal axis of the main body of needle hub 11). Regarding claim 32, Gargione discloses a kit for administering a product in liquid or semi-liquid form (pg. 3; Fig. 5A showing syringe assembly 10 and adaptor 30) comprising a dosing syringe (Fig. 2B, syringe assembly 10) comprising: a hollow cylindrical body (Fig. 1, hollow cylindrical body 12) and a plunger sliding within the hollow cylindrical body (Fig. 1, elongated plunger 22; pg. 7 ln. 12-22), the hollow cylindrical body comprising a main body and a proximal end provided with an aperture (Ex. Fig. 1 showing main body and proximal end provided with aperture 20); wherein the proximal end is removable and blocked between a side surface of the adapter and a bottom wall provided with an aperture of the adapter (pg. 7 ln. 2-11 and 19-22 and pg. 8 ln. 1-3; Ex. Fig. 1 showing proximal end snugly seated in interior wall 44 of adaptor 30 and triangular shaped leaves 60 sealed about central aperture 56 of adaptor 30), the aperture of the proximal end and the aperture of the bottom wall being in direct fluid communication therebetween (Ex. Fig. 1 showing aperture 20 of the proximal end in direct fluid communication with central aperture 56 comprising leaves 60) and the adaptor comprises a hollow cylindrical body (Fig. 5B, cylindrical body 32 of adaptor 30) and a flange extending from the hollow cylindrical body (Fig. 5B, flange 34 extending from cylindrical body 32); wherein the hollow cylindrical body comprises a bottom wall including an aperture configured to abut against the hemispherical proximal end of the dosing syringe (Fig. 5B, cylindrical body 32 comprising bottom wall 54 including aperture 56 comprising leaves 60 configured to abut against proximal end of syringe assembly 10) Gargione differs from the instantly claimed invention in that Gargione fails to disclose the main body that has at least one portion having a cross-section smaller than that of the proximal end, wherein a surface is delimited between the main body and the proximal end, which is configured to abut against a corresponding surface of an adaptor, and the adaptor comprising an annular tooth extending internally to the hollow cylindrical body, and which delimits an annular surface configured to abut against the abutment surface. Kopfer teaches a connector for a syringe that has at least one portion having a cross-section smaller than that of the proximal end (Ex. Fig. 2 showing main body of needle hub 11 having groove 14 smaller than some sections of the proximal end of needle hub 11), wherein a surface is delimited between the main body and the proximal end, which is configured to abut against a corresponding surface of an adaptor (Ex. Fig. 2 showing abutment surface configured to abut against annular rim 24/24’ on adaptor 20), and an adaptor comprises an annular tooth extending internally to the hollow cylindrical body and above the bottom wall, and which delimits an annular surface configured to abut against the abutment surface of the hollow cylindrical body of the dosing syringe (Ex. Fig. 2 showing annular tooth 24/24’ extending internally delimiting an annular surface that abuts against abutment surface). It would be considered obvious to one of ordinary skill in the art before the effective filing date of the instant application to modify the main body and adaptor of Gargione to comprise the connection means as taught by Kopfer, because Kopfer teaches that this provides for a releasable, locked engagement (col. 3 ln. 64-67 and col. 4 ln. 1-12), which would provide further security to the friction-fit connection of Gargione’s syringe and adaptor when filling the syringe. Fisher provides evidence that a luer slip adaptor could be improved upon as it allows for motion and loosening between the syringe and the device (para. 0004) and can leak fluid if improperly seated (para. 0007). In the modification of Gargione with Kopfer, the dosing syringe of Gargione would comprise all of the connection mechanisms of the body of the connector of the syringe as taught by Kopfer and the adaptor of Gargione would comprise all of the connection mechanisms of the adaptor as taught by Kopfer; therefore, the groove (14) of Kopfer would be considered the portion of the main body of Gargione that has a smaller cross-section than the proximal end, the abutment surface (Ex. Fig. 2) of Kopfer would be considered the surface of Gargione that is delimited between the main body and proximal end, and the annular tooth (24/24’) of Kopfer would be considered the corresponding surface of the adaptor of Gargione.
