Office Action

§DP
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 . Double Patenting 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. Claim 1-14 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of U.S. Patent No. 9833588 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘588 patent are more narrow than claims 1-14 of the instant application. Claim 1-14 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-13 of U.S. Patent No. 10328277 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘277 patent are more narrow than claims 1-14 of the instant application. Claim 1-15 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of U.S. Patent No. 11376389 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘389 patent are more narrow than claims 1-15 of the instant application. Claim 1-15 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11998699 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘699 patent are more narrow than claims 1-14 of the instant application. Allowable Subject Matter The closest pieces of prior art are Koenig (US 3,169,529), Linderoth (US 2002/0029782 A1) Hinshaw et al. (US 4,306,743 A), Blease (GB 649,230). Regarding claims 1 and 11, the prior art fails to anticipate or make obvious, the three levels of protection claimed (threaded connection, BNC connection and pressure relief valve on elbow). While threaded connections and BNC connectors are known in the art, the combination of the inner/outer cannula threaded connection, BNC connector between the inserting cannula and elbow adaptor, and the elbow adaptor having a pressure release valve is unique. Koenig teaches a threaded connection between inner and outer cannular (see figure 5). Blease discloses BNC connectors between various components (see figures 1-5). The BNC connection in Blease is not between the inserting cannula (7) and an elbow adapter (figure 2), but between 7 and neck plate (figure 1) and further Blease fails to disclose wherein the two or more channels are arcs that are curved 90 degrees or more and extend longitudinally as claimed in the instant application. Linderoth teaches an elbow adaptor connector (E) attached to an inserting cannula (figure 5), but fails to teach or disclose the type of BNC connector claimed. Hinshaw teaches BNC connectors as a safety arrangement (figures 1-6). It would be impermissible hindsight to modify all the connections and arrangements of components in the prior art to arrive at the claimed invention.
