CTNF 18/580,435 CTNF 69182 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. 07-06 AIA 15-10-15 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 07-21-aia AIA Claim s 1-8 are rejected under 35 U.S.C. 103 as being unpatentable over KR 101934756B1 . KR 101934756B1 teaches treating magnesia-carbon waste refractory material with a water treatment step, then drying (which reads on the instantly claimed heat treatment) to evaporate moisture, then grinding (which reads on the instantly claimed pulverizing. The treated product may be used/reused as a refractory. Unlike the instant invention, KR 101934756B1 does not specify the water treatment or drying temperatures. Those persons having ordinary skill in the art would have found it obvious to conduct routine experimentation of these parameters in order to determine the best results.
