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. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale , or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1 is/are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Lim (CN 110114183) with references made to US equivalent (US 2021/0162529) Lim discloses, Regarding claim 1, A coolant drop prevention system for preventing, when electrodes are removed from a tip of a welding gun in a spot welder (a welding gun having a coolant blocking system for preventing coolant from leaking when a tip is being replaced. See Abstract) , coolant circulated into the electrodes through a coolant supply passage and a coolant discharge passage from dropping from the tip of the welding gun, (coolant is circulated through coolant supply passage 27 and coolant discharge passage 33, See Paragraph [0035], and Fig 1) the coolant drop prevention system comprising: a first stop valve at an intermediate position along the coolant supply passage to stop supply of the coolant into the electrodes; (a first valve 15 is positioned along the coolant supply passage controlled by blocking the coolant from flowing into the electrodes, See Paragraph [0050] and Fig 2) a second stop valve at an intermediate position along the coolant discharge passage to stop discharge of the coolant from the electrodes; (A second valve 19 is shown as being along the coolant discharge passage to stop discharge of the coolant. See Paragraph [0054] and Figs 3 and 5C) a first pipe having a first end connected to a portion of the coolant supply passage closer to the welding gun than the first stop valve; (main supply pipeline 25 is connected to the coolant supply closer to the welding gun, See Figs 1-4) a second pipe having a first end connected to a portion of the coolant discharge passage closer to the welding gun than the second stop valve; (Main discharge is connected closer than the second valve. See Figs 1-4) a drain pipe having a first end connected to a portion of the coolant discharge passage farther from the welding gun than the second stop valve; (manifold 55 or suction pipeline functions as a drain and would be located further from the welding gun based on the circuit. See Fig 4. Element 55 is located on a separate circuit after the suction device 37. Fig 5A also shows a coolant out passage which could be considered a drain) and a pump unit connected to a second end of each of the first pipe, the second pipe, and the drain pipe to suck in the coolant from the first pipe and the second pipe and discharge the sucked coolant into the drain pipe. (Suction means 35 functions as a pump for sucking the coolant from the first pipe and the second pipe into the discharge pipe 31, See Paragraph [0041]) Allowable Subject Matter Claim 2 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
