Office Action

§102
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 . The instant application with Application Number 18/395,520 filed on 12/23/2023 is presented for examination. Claims 1-130 are pending. Information Disclosure Statment The Information Disclosure Statement dated 12/23/2023 is acknowledged and the cited references have been considered in this examination. Priority Receipt is acknowledged of certified copies of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Double Patenting The non-statutory 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 non-statutory 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 non-statutory 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 non-statutory 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 is provisionally rejected on the ground of non-statutory double patenting as being unpatentable over claim of co-pending Application No. 18/644,958. Although the claims at issue are not identical, they are not patentably distinct from each other because they both claim similar system/a fluid channel assembly for a connector of an Electric Vehicle (EV) charging gun, comprising: a fluid channel network for cooling a contact pin of the EV charging gun. This is a provisional non-statutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claim 1 of instant application 18/395,520 Claim 1, of co-pending application: 18/664,958 A fluid channel assembly for a connector of an Electric Vehicle (EV) charging gun, comprising: a fluid channel network for cooling a contact pin of the EV charging gun; a fluid inlet connected to the fluid channel network, the fluid inlet being configured to receive a coolant through an EV charging cable and to inject the coolant into the fluid channel network; a fluid outlet connected to the fluid channel network, the fluid outlet being configured to receive the coolant from the fluid channel network and to inject the coolant into the EV charging cable; wherein the fluid channel network is arranged around the contact pin and wherein the fluid in the channel network is in direct or indirect contact with the contact pin. A system for a connector of a charging gun for an electric vehicle, the system comprising: a contact pin of the charging gun and a fluid channel assembly, the fluid channel assembly comprising: a fluid channel network for cooling configured to cool a contact pin of the charging gun, wherein the fluid channel network is arranged around the contact pin and is in direct or indirect contact with the contact pin; a fluid inlet connected to the fluid channel network via a first single fluid transfer channel, the fluid inlet being configured to receive a coolant through a charging cable and to inject the coolant into the fluid channel network; a fluid outlet connected to the fluid channel network via a second single fluid transfer channel, the fluid outlet being configured to receive the coolant from the fluid channel network and to inject the coolant into the charging cable… Claims 2-8 are dependent on rejected claim 1 above, hence rejected. Claim 9 is provisionally rejected on the ground of non-statutory double patenting as being unpatentable over claim of co-pending Application No. 18/644,958. Although the claims at issue are not identical, they are not patentably distinct from each other because they both claim similar connector for an electric vehicle charging station, the connector comprising: a system comprising a contact pin of a charging gun for an electric vehicle and a fluid channel assembly. This is a provisional non-statutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claim 9 of instant application 18/395,520 Claim 10, of co-pending application: 18/664,958 A connector for an Electric Vehicle (EV) charging station, comprising: a fluid channel assembly comprising: a fluid channel network for cooling a contact pin of the EV charging gun; a fluid inlet connected to the fluid channel network, the fluid inlet being configured to receive a coolant through an EV charging cable and to inject the coolant into the fluid channel network; a fluid outlet connected to the fluid channel network, the fluid outlet being configured to receive the coolant from the fluid channel network and to inject the coolant into the EV charging cable; wherein the fluid channel network is arranged around the contact pin and wherein the fluid in the channel network is in direct or indirect contact with the contact pin; an inlet; an outlet; transfer channels; a fluid channel network; a contact pin (330); a contact terminal comprising an outlet for connecting outflow tubes, an inlet for connecting an inflow tube, and structures for connecting the at least one copper conductor on a first side and means for connecting the contact pin on a second side; wherein the contact terminal is configured to accommodate the first and the second single fluid transfer channels; and wherein the fluid channel network is arranged around the contact pin and the fluid in the channel network is in thermal contact with the DC contact pin.
