Office Action

§102 §112
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 . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-8 and 11-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 1, 2, 6, and 11 are rejected as being indefinite because it is unclear whether these claims are directed to a cleaning device alone or to a cleaning device attached to a support. The preambles of each of these claims recite “a cleaning device adapted to be attached to a support”, which indicates the invention is directed to a cleaning device alone; however, line 5 of each of these claims further positively recites “an inner face of the support” , which would indicate the invention is directed to a cleaning device attached to a support. Claims 3-5, 12, and 13 are rejected for depending from indefinite claim 1. Claims 14-18 are rejected for depending from indefinite claim 2. Claims 7-8 and 19-20 are rejected for depending from indefinite claim 6. Claim 8 recites the limitation "the guide" in line 4. There is insufficient antecedent basis for this limitation in the claim. 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. Claims 1-22 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ishikawa (JP 2014-193649).

Regarding claim 2, Ichikawa teaches a cleaning device (fig. 2) adapted to be attached to a support (100) having an opening (101), the cleaning device comprising: a nozzle (4) configured to jet fluid toward a target (300); a bracket (5) holding the nozzle in place (figs. 1, 2); and an adhesive portion (23, which is interpreted to be “adhesive” since these form a portion that holds fast by grasping) adhering the bracket to an inner face of the support (p. 5, ln. 3-13; fig. 1), wherein the bracket includes a guide having a recessed face (20) that is configured to guide the fluid toward the target (fig. 1; p. 3, ln. 27-32); wherein the nozzle is disposed so as to be at least partially covered by the support when the cleaning device is attached to the support (fig. 1 – the nozzle is at least partially “concealed” by the support); and wherein an outer edge of the guide is configured to be located inside an inner edge of the opening when the cleaning device is attached to the support (figs. 1, 2). Regarding claim 3, Ichikawa teaches the cleaning device described regarding claim 1, and further comprising: a deflector (22) configured to deflect the fluid toward the target (figs. 1, 2). Regarding claim 4, Ichikawa teaches the cleaning device described regarding claim 1, and further wherein the bracket is formed with an aperture (6) that allows at least the fluid to pass through (fig. 1); and wherein the opening is disposed so as to be covered by the support at least at a position where is vertically under the nozzle when the cleaning device is attached to the support (fig. 1). Regarding claim 5, Ichikawa teaches the cleaning device described regarding claim 1, and further wherein the bracket is formed with an aperture (9a) that allows at least the fluid to pass through (p. 2, ln. 33); and wherein the opening is disposed so as to face the guide (fig. 1). Regarding claim 6, Ichikawa teaches a cleaning device (fig. 2) adapted to be attached to a support (5/100) having a recessed face (20, see fig. 1), the cleaning device comprising: a nozzle (4) configured to jet fluid toward a target (fig. 1); a bracket (3) holding the nozzle in place (see p. 3, ln. 19-20; fig. 1); and an adhesive portion (11/12, which is interpreted to be “adhesive” since these form a portion that holds fast by grasping) adhering the bracket to an inner face of the support (p. 4, ln. 25-29; fig. 1), wherein the bracket includes an opening (10) configured to receive the recessed face at a side corresponding to the inner face of the support (fig. 1 – the upper end of bracket 3 is open at 10 and together with the recessed face 20 forms the spray path); wherein the nozzle is disposed such that the fluid is guided toward the target by the recessed face when the cleaning device is attached to the support (fig. 1); and wherein the nozzle is disposed so as to be at least partially covered by the support as viewed from a side corresponding to an outer face of the support when the cleaning device is attached to the support (fig. 1 – the nozzle is at least partially “concealed” by the support). Regarding claim 7, Ichikawa teaches the cleaning device described regarding claim 6, and further wherein the bracket is formed with an aperture (6) that allows at least the fluid to pass through (fig. 1); and wherein the opening is disposed so as to be covered by the support at least at a position where is vertically under the nozzle when the cleaning device is attached to the support (fig. 1). Regarding claim 8, Ichikawa teaches the cleaning device described regarding claim 6, and further wherein the bracket is formed with an aperture (9a) that allows at least the fluid to pass through (p. 2, ln. 33); and wherein the opening is disposed so as to face the guide (fig. 1). Regarding claim 9, Ichikawa teaches a cleaning device (fig. 2) adapted to be attached to a support having a recessed face (20, see fig. 1), the cleaning device comprising: a nozzle (4) configured to jet fluid toward a target (fig. 1); and an engaging portion (10) configured to engage with the support at a side corresponding to an inner face of the support to hold the nozzle in place (see p. 3, ln. 19-20), wherein the nozzle is disposed such that the fluid is guided toward the target by the recessed face when the cleaning device is attached to the support (fig. 1, 2); and wherein the nozzle is disposed so as to be at least partially covered by the support as viewed from a side corresponding to an outer face of the support when the cleaning device is attached to the support (figs. 1, 2). Regarding claim 10, Ichikawa teaches the cleaning device described regarding claim 9, and further wherein the nozzle is disposed such that the fluid is deflected toward the target by a part of the recessed face when the cleaning device is attached to the support (fig. 1). Regarding claim 11, Ichikawa teaches a cleaning device (fig. 2) adapted to be attached to a support (100) having an opening (101), the cleaning device comprising: a nozzle (4) configured to jet fluid toward a target (300); a bracket (5) holding the nozzle in place (fig. 1, 2); and an adhesive portion (23, which is interpreted to be “adhesive” since these form a portion that holds fast by grasping) adhering the bracket to an inner face of the support (p. 5, ln. 3-13; fig. 1), wherein the nozzle is disposed such that the fluid that has passed the opening is jetted toward the target when the cleaning device is attached to the support (fig. 1); and wherein the nozzle is disposed so as to be at least partially covered by the support as viewed from a side corresponding to an outer face of the support when the cleaning device is attached to the support (figs. 1, 2 – by portion 16).
