Therefore it would have been obvious to one of ordinary skill before the effective filling date of the claimed invention was made to modify the system of Frank in view of CN by using a filter configured to remove contaminants from exhaust gasses passing therethrough; and a vent configured to direct exhaust gasses through the filter and to direct an air stream in which a downstream direction is a direction in which air is guided through the filter, wherein the filter is downstream of the ignition device such that the ignition device is configured to combust the exhaust gases prior to the exhaust gases being directed through the filter, as taught by Sculto in order to achieve efficient testing of exhaust gas (Sculto; [0019]). Regarding Claim 14, Frank in view of CN in view of Sculto teaches the exhaust gas treatment device of claim 13. Frank in view of CN is silent about wherein the filter comprises a cyclone filter adjacent to and downstream of the ignition device. Sculto further teaches wherein the filter comprises a cyclone filter adjacent to and downstream of the ignition device (filter 22 performs at high temperature regeneration of particles, therefore 22 is cyclone filter; See [0014]). Therefore it would have been obvious to one of ordinary skill before the effective filling date of the claimed invention was made to modify the system of Frank in view of CN by using the filter comprises a cyclone filter adjacent to and downstream of the ignition device, as taught by Sculto in order to achieve efficient testing of exhaust gas (Sculto; [0019]). Regarding Claim 16, Frank in view of CN in view of Sculto teaches the exhaust gas treatment device of claim 14. Frank in view of CN is silent about further comprising a second gas inlet between the ignition device and the filter and configured to introduce non-exhaust gases to exhaust gases after the combustion thereof and prior to the combusted exhaust gases being directed through the filter. Sculto further teaches further comprising a second gas inlet between the ignition device and the filter (second gas inlet 20 between 16 and 22 in Fig. 1; See [0013]) and configured to introduce non-exhaust gases to exhaust gases after the combustion thereof and prior to the combusted exhaust gases being directed through the filter (20 introduces non-exhaust gases/oxidation catalyst before going to filter 22 and after combustion from 16 in fig. 1; See [0013]). Therefore it would have been obvious to one of ordinary skill before the effective filling date of the claimed invention was made to modify the system of Frank in view of CN by using a filter configured to remove contaminants from exhaust gasses passing therethrough; and a vent configured to direct exhaust gasses through the filter and to direct an air stream in which a downstream direction is a direction in which air is guided through the filter, wherein the filter is downstream of the ignition device such that the ignition device is configured to combust the exhaust gases prior to the exhaust gases being directed through the filter, as taught by Sculto in order to achieve efficient testing of exhaust gas (Sculto; [0019]). Regarding Claim 17, Frank in view of CN in view of Sculto teaches a method for exhaust gas treatment in the battery testing system as claimed in claim 1. Frank further teaches the method comprising: performing a battery test procedure on a battery; igniting exhaust gases produced during the battery test procedure to combust the exhaust gases; Frank in view of CN is silent about guiding the combusted gases through a filter; and filtering pollutants from the guided combusted gases. Sculto teaches guiding the combusted gases through a filter (filter 22 in fig. 1; See [0014]); and filtering pollutants from the guided combusted gases (filtering from guided combustion gas 16 in fig. 1; See [0014]); Therefore it would have been obvious to one of ordinary skill before the effective filling date of the claimed invention was made to modify the system of Frank in view of CN by guiding the combusted gases through a filter; and filtering pollutants from the guided combusted gases, as taught by Sculto in order to achieve efficient testing of exhaust gas (Sculto; [0019]). Allowable Subject Matter Claim 10 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. Regarding Claim 10, none of the prior art fairly teaches or suggests the battery testing system of claim 8, wherein the hood structure comprises a safety flap mounted on a top portion of the hood structure such that: when the vent is operated, the generated air stream forces the safety flap to a closed position against a safety outlet in the hood structure thereby directing the air stream to a gas outlet in the hood structure; and when the vent is not operated, the safety flap is released to an open position away from the safety outlet in the hood structure thereby permitting a flow of exhaust gases through the safety outlet in the hood structure, wherein the test chamber comprises an air inlet configured to provide air from outside the test chamber into the test chamber.
