CTNF 18/518,973 CTNF 91138 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Double Patenting 08-33 AIA The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg , 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman , 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi , 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum , 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel , 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington , 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA/25, or PTO/AIA/26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. 08-34 AIA Claim s 1-18 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim s 1-15 of U.S. Patent No. 12208229B1 . Although the claims at issue are not identical, they are not patentably distinct from each other because - claim 1 recites the limitation a method of connecting a first tubing to a second tubing for aseptic fluid transfer (Patent, Claim 1, Col. 6, lines 37-67), comprising: placing the first tubing within a first channel and the second tubing within an opposing channel (Patent, Claim 1, Col. 6, lines 37-67); attaching a male connector to a female connector (Patent, Claim 1, Col. 6, lines 37-67); attaching a first tape with adhesive on one surface to a portion of the first tubing (Patent, Claim 1, Col. 6, lines 37-67); attaching the second tape with adhesive on one side to a portion of the second tubing (Patent, Claim 1, Col. 6, lines 37-67), wherein the second tape has sufficient length to extend past the distal end of the female connector and placing the mating surfaces of the holders (Patent, Claim 1, Col. 7, lines 1-6). Claim 1 of the current application is border that claim of the patent as it is has no tape adhesive on tape that extend from the end of the connectors. Also, the limitation of claims 2-18 of the current application can be found in claims 1-15 of the patent such as: claim 2 ( Patent, Claim 2), claim 3 (Patent, Claim 1), claim 4 (Patent, Claim 4), claim 5 (Patent, Claim 5), claim 6 (Patent, Claim 6), claim 7 (Patent, Claim 7), claim 8 (Patent, Claim 8), claim 9 (Patent, Claim 9), claim 10 (Patent, Claim 10), claim 11(Patent, Claim 11), claim 12 (Patent, Claim 12), claim 13 ( Patent, Claim 13), claim 14 (Patent, Claim 1), claim 15 (Patent, Claim 1), claim 16 (Patent, Claim 1), claim 17 (Patent, Claim 13), claim 18 (Patent, Claim 18) .

Re Claim 16, Tenczar discloses wherein the elastic material is formed from flexible layer/layers (34, Col. 4, line 15) . Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-21-aia AIA Claim (s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tenczar in view of Kellogg (US. 4418945) . Re Claim 2, Tenczar fails to disclose further including attaching a third tape with adhesive on one surface to a portion of the male connector and to a portion of the first tubing such that said third tape opposes said first tape, and adhering the adhesive surface of said third tape to the opposed adhesive surface of the first tape; attaching a fourth tape with adhesive on one surface to a portion of the female connector and a portion of the second tubing such that said fourth tape opposes said second tape, and adhering the adhesive surface of said fourth tape to the opposed adhesive surface of the second tap; pulling the ends of the first tape and the third tape apart and pulling the ends of the second tape and the fourth tape apart so that the male connector is pulled inside the female connector. However, Kellogg discloses a method of connecting tubings (abstract, Figs. 11-13) including attaching a third tape (13 tape attaches to left 16 on top side) with adhesive on one surface to a portion of the male connector (left 1, Fig. 11) and to a portion of the first tubing (left 16 on right side) such that said third tape opposes said first tape (left 15), and adhering the adhesive surface of said third tape to the opposed adhesive surface of the first tape (Col. 4, lines 25-40, Fig. 11); attaching a fourth tape (13 tape attaches to right 16 on lower side) with adhesive on one surface to a portion of the female connector (right 1) and a portion of the second tubing such that said fourth tape opposes said second tape (right 16 on the left side), and adhering the adhesive surface of said fourth tape to the opposed adhesive surface of the second tap (right 15); pulling the ends of the first tape and the third tape apart (left and top 20, 12) and pulling the ends of the second tape and the fourth tape apart so that the male connector is pulled inside the female connector lower 12 and right 20, Col. 6, line 60 up to Col 7 lines 10). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify method of Tenczar to include including attaching a third tape with adhesive on one surface to a portion of the male connector and to a portion of the first tubing such that said third tape opposes said first tape, and adhering the adhesive surface of said third tape to the opposed adhesive surface of the first tape; attaching a fourth tape with adhesive on one surface to a portion of the female connector and a portion of the second tubing such that said fourth tape opposes said second tape, and adhering the adhesive surface of said fourth tape to the opposed adhesive surface of the second tap; pulling the ends of the first tape and the third tape apart and pulling the ends of the second tape and the fourth tape apart so that the male connector is pulled inside the female connector as taught by Kellogg for the purpose of keeping the tube in a sterilized status in an art recognized sterilization (Kellogg, Col. 6, line 60 up to Col 7 lines 10) . 07-21-aia AIA Claim (s) 5, 17-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tenczar in view of Johnson et al. (US. 20030030272A1) ("Johnson") . Re Claim 5, Tenczar fails to disclose a pinch valve on the first or second tubing to prevent fluid flow to the male or female connector before the connection is made. However, Johnson discloses a pinch valve on the first or second tubing to prevent fluid flow to the male or female connector before a connection is made (Fig. 6, 200 valve, tube 190). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify method of Tenczar to include a pinch valve on the first or second tubing to prevent fluid flow to the male or female connector before a connection is made as taught by Johnson for the purpose of keeping the tube in a sterilized status (Johnson, ¶0081). Re Claim 17, Tenczar fails to disclose a secondary sterilisation procedure using an aerosolized or gaseous sterilisation applied to the connector to further reduce the risk of contamination. However, Johnson discloses connected tube comprising a secondary sterilisation procedure using an aerosolized or gaseous sterilisation applied to the connector to further reduce the risk of contamination (¶0081). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify method of Tenczar to include a secondary sterilisation procedure using an aerosolized or gaseous sterilisation applied to the connector to further reduce the risk of contamination as taught by Johnson for the purpose of keeping the tube in a sterilized status in an art recognized sterilization (Johnson, ¶0081). Re Claim 18, Tenczar fails to disclose wherein sterilisation is performed using steam, atomised ethanol or ethylene gas. However, Johnson discloses connected tube comprising sterilisation is performed using steam, atomised ethanol or ethylene gas (¶0081). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify method of Tenczar so that sterilisation is performed using steam, atomised ethanol or ethylene gas as taught by Johnson for the purpose of keeping the tube in a sterilized status in an art recognized sterilization (Johnson, ¶0081) . 07-21-aia AIA Claim (s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tenczar in view of Faldt et al. (US. 10946183B2) ("Faldt") . Re Claim 8 , Tenczar fails to disclose a plurality of first and second tubings to form multiple fluid networks. However, Faldt discloses a multiple connector together to join multiple fluid networks at once (Fig. 1, 120 tubes and 126 connectors, abstract). Thus, it would have been prima facie obvious to one having ordinary skill in the art at the time the invention was made to have modify method of Tenczar to have plurality of first and second tubings to form multiple fluid networks as taught by Faldt for the purpose connecting multiple lines together for multiple fluid flow at once (Faldt, Col. 4, lines 50-65).
