Office Action

§102 §103
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 amendment filed on 2/25/2026 has been entered. Claim Objections The following claim is objected to because of the following informalities: In claim 1, line 2, the term “An” has typographical error. Appropriate corrections are required. 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. Claims 1 and 3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lee (KR 200398227 Y1). Regarding claim 1, Lee discloses a fill nozzle (fig.1-5) comprising: an angled tube (13, fig.3) having a first end (by marked area 12) and a second end (by marked area 14); wherein the angled tube is comprised of one tube (see fig.2-3); a valve connected to the first end of the angled tube (12); a fire hose connection (11) having a first end (area 11a) and a second end (area of 11 connected to 12), wherein the first end of the fire hose connection is configured to connect to a fire hose (2, via 3), and the second end of the fire hose connection is connected to the valve (see fig.2-3); and wherein the second end of the angled tube is configured to expel fluid (see fig.3). Regarding claim 3, Lee discloses a handle (15) attached to the first end of the angled tube. Claim Rejections - 35 USC § 103 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 2 is rejected under 35 U.S.C. 103 as being unpatentable over Lee (KR 200398227 Y1) in view of Lee Young-hyun (KR 200256304 Y1). Lee is silent in disclosing the second end of the angled tube further comprises a plurality of apertures configured to expel the fluid. However, Lee Young-hyun teaches the commonality of having the second end of the angled tube further comprises a plurality of apertures configured to expel the fluid (113, fig.1 and see attached translation, page 3, ll.28-31). It would have been obvious to one having ordinary skill in the art before the effective filling date of the application to modify the second end of the tube of Lee as such to include a plurality of apertures as taught by Lee Young-hyun, in order to be able to spray a large area of an object. Response to Arguments Applicant’s arguments with respect to the above claims have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
