Office Action

§102 §103
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 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. 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 and 19 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Smith (US 2015/0097060). As to claim 1, Smith discloses a spray gun comprising: A head for spray nozzle to spray paint A handle formed on the lower portion of the head Side air nozzles with vertical slits (figure 1, 48 and 58) Lower and Upper nozzles with horizontal slits (figure 1, 28 and 38) Air is sprayed from the upper, lower, and side nozzles (figure 11). As to claim 19, slit is formed in an arc-shaped curve (figure 1). Claim Rejections - 35 USC § 103 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. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 2-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Smith (US 2015/0097060). As to claims 2 and 3, Smith discloses upper, lower, and side nozzles, but fail to teach gasket and a cut groove having a “U” shape. However, it would have been obvious to one of ordinary skill in the art to modify the slit of Smith to include a shape that would produce an effective spraying angle to control the paint particles from scattering all over. As to claims 4-6, Smith discloses slits and controlling of the flow, but fails to teach spreader between inclined portions, separators for separating flow from the cut groove. However, it would have been obvious to one of ordinary skill in the art to modify the airflow depending on the design choice and controlling of the airflow. As to claim 7, Smith shows that the side air nozzles spray the air through slits and capable of temporarily accommodating the air supplied in the through-hole. Allowable Subject Matter Claims 8-18 and 20 are 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.
