Office Action

§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 . Response to Amendment This office action is responsive to the amendment filed on 3/10/26. As directed by the amendment: claims 1, 2, 11, 16, and 17 have been amended, claims 3 and 18 have been cancelled, and no new claims have been added. Thus, claims 1, 2, 4-17, 19, and 20 are presently pending in this application. The amendments to the claims are sufficient to overcome the rejections under 35 U.S.C. 112(b) from the prior action. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 2, 4-17, 19, and 20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding independent claims 1, 11, and 16, there is insufficient written description for the newly recited limitation of “a molded bellows structure” in the original disclosure, which constitutes new matter. The remaining claims inherit the deficiencies of their respective parent independent claim. 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. Claim(s) 1, 2, 4-17, 19, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Vandenbrink et al.

However, Burkholz et al. is in the field of an extension set for vascular access (para. [0007]) and teaches a system (Fig. 2, extension set 100 and PIVC 200 define a system), comprising a connection portion (Fig. 1A, extension set 100) having a distal end (Fig. 1A, distal end 100a) and a proximal end (Fig. 1A, proximal end 100b), the connection portion (Fig. 1A, extension set 100) comprising a connector interface (Fig. 1A, distal connector 110) disposed at the distal end (Fig. 1A, distal end 100a) and a fluid path member (Fig. 1A, extension tube 120) fluidly coupled to the connector interface (Fig. 1A, distal connector 100) and configured to be coupled to the fluid connector component of the fluid access assembly (Fig. 2, extension tube 120 is coupled to a fluid connector component of vacuum tube receiver 220 via connector 130; para. [0029]-[0030]; para. [0040]; para. [0047]), wherein the fluid path member (Fig. 1A, extension tube 120) is configured to reduce hemolysis of a blood sample passing therethrough (Fig. 1A, the configuration of extension tube 120 is optimized to minimize hemolysis while providing adequate flow rate; para. [0031]), and wherein the connection portion (Fig. 1A, extension set 100) comprises a compact connector (Fig. 1A, Fig. 2, extension set 100 defines a compact connector), the compact connector (Fig. 1A, Fig. 2, the defined compact connector) comprising a proximal connector portion (Fig. 1A, proximal connector 130) configured to couple the compact connector (Fig. 1A, Fig. 2, the defined compact connector) to the fluid connector component (Fig. 1A, Fig. 2, proximal connector 130 is configured in any form that would enable another device, such as vacuum tube 220, to be connected to extension set 100; para. [0030]; para. [0038]; para. [0040]), a distal connector portion (Fig. 1A, distal connector 110) 10) configured to couple the compact connector (Fig. 1A, Fig. 2, the defined compact connector) to an access port of a vascular access device (Fig. 1A, Fig. 2, distal connector 110 is configured in any form that would enable it to be coupled to a vascular access device; para.

[0031]; Bullington et al., para. [0136]), thereby minimizing sample damage during collection. Regarding claim 2, modified Vandenbrink et al. discloses the system of claim 1. Vandenbrink et al. does not explicitly disclose wherein the fluid path member comprises a flexible tube. However, Burkholz et al. is in the field of an extension set for vascular access (para. [0007]) and teaches a system (Fig. 2, extension set 100 and PIVC 200 define a system), wherein the fluid path member comprises a flexible tube (Fig. 1A, element 140). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Vandenbrink et al. to include a tube as taught by Burkholz et al., the motivation being to allow selective access to tube 120 while also shielding from exposure to blood or other fluids (Burkholz et al., para. [0038]). Regarding claim 4, modified Vandenbrink et al. discloses the system of claim 1. Vandenbrink et al. does not explicitly disclose wherein the connector interface comprises one of a threaded luer, a slip luer, a threaded luer lock with collar, a blunt plastic cannula, a male luer, a cannula for PRN access,aneedle-free connector, or a needle access cannula.

[0007]) and teaches a system (Fig. 2, extension set 100 and PIVC 200 define a system), wherein the connector interface (Fig. 1A, distal connector 110) comprises one of a threaded luer, a slip luer, a threaded luer lock with collar, a blunt plastic cannula, a male luer, a cannula for PRN access, a needle-free connector, or a needle access cannula (Fig. 1A, distal connector 110 is configured in any form, includinga blunt cannula snap connect, athreated male luer, asslip luer: para. [0030]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Vandenbrink et al. to include connector as taught by Burkholz et al., the motivation being to facilitate connection to a vascular access device (Burkholz et al., para. [0030]). Regarding claim 5, modified Vandenbrink et al. discloses the system of claim 1. Regarding wherein the fluid component connector is integrated with the fluid access assembly, It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention for the fluid component connector to be integrated with the fluid access assembly, since the use of a one piece construction would have required only routine skill in the art. The motivation for doing so would have been to minimize part shifting and simplify manufacture. Regarding claim 6, modified Vandenbrink et al. discloses the system of claim 1. Regarding wherein the fluid component connector is removably coupled to the fluid access assembly, It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention for the fluid component connector to be removably coupled to the fluid access assembly, since separating parts involves only routine skill in the art. The motivation for doing so would have been to facilitate sterilization of parts. Regarding claim 7, modified Vandenbrink et al. discloses the system of claim 1, Vandenbrink et al. further disclosing wherein the container assembly (Fig. 2B, container assembly 210) is configured to be transitioned from the first configuration to a second configuration (Fig. 2G, the system 200 is transitioned from the firsts configuration to a second configuration; para.
