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 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 21-25 and 30-31 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chappell (US 8,726,534). The claims are reasonably and broadly construed in light of the accompany specification, to be disclosed by Chappell as teaching: a shoe care device (see title and abstract and column 6 lines 7-9) comprising: an accommodation space 12 configured to accommodate shoes; an outer cabinet 10, 82 defining an exterior of the shoe care device (column 8 line 60 through column 9 line 2); a blower 30 configured to circulate air in the accommodation space; a power supply (column 7 lines 4-9) configured to supply power to the blower; an electrical inlet electrically connected to the power supply, the electrical inlet being configured such that external power enters therethrough (column 9 lines 2-13); and an electrical outlet electrically connected to the power supply, the electrical outlet being configured such that power exits therethrough (column 10 lines 36-46). Chappell also discloses the claim 22 feature wherein the electrical inlet and the electrical outlet are located on a rear surface of the outer cabinet (figures 6, 13b). the claim 23 feature wherein the electrical inlet is exposed at one side of the outer cabinet, and wherein the shoe care device further comprises a flap coupled to the outer cabinet, the flap being configured to selectively shield or expose the electrical outlet (column 10 lines 3-35), the claim 24 feature of an outlet hole extending through the outer cabinet, the electrical outlet being exposed through the outlet hole; a hinge coupling the flap to the outer cabinet at an edge of the outlet hole; and a flap spring configured to elastically bias the flap in a direction in which the flap shields the outlet hole (column 10 lines 3-35), the claim 25 feature wherein the flap and the flap spring are located inside the outer cabinet, and wherein the flap is configured to open the outlet hole when an outer surface of the flap is pressed inward (column 10 lines 3-35), the claim 31 feature of power cord including an inlet connector, the inlet connector being configured to be detachably connected to the electrical inlet; and a connection cord including: a first connector configured to be detachably connected to the electrical outlet; a second connector configured to be detachably connected to the electrical inlet; and a cable electrically interconnecting the first connector and the second connector, wherein the first connector is coupled to the electrical outlet, and wherein the first connector is not coupled to the electrical inlet (column 10 lines 36-45), the claim 31 feature a connection cord including: a first connector configured to be detachably connected to the electrical outlet, the first connector having a terminal; a second connector configured to be detachably connected to the electrical inlet; and a cable electrically interconnecting the first connector and the second connector, wherein the electrical outlet includes a movable pin, and wherein, when the first connector is coupled to the electrical outlet, the movable pin of the electrical outlet moves outward to be electrically connected the terminal of the first connector (figures 6, 13b). Claim 37 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Eichten (US 5,592,758). The claims are reasonably and broadly construed in light of the accompany specification, to be disclosed by Eitchten as teaching: a shoe care system (see title and abstract and column 4 line 43) comprising: two or more shoe care devices 151, 160 each shoe care device including: an accommodation space 111 configured to accommodates shoes (column 4 lines 18-45, especially line 43); an operation unit 113 configured to adjust one or more of temperature 112, humidity, and air flow in the accommodation space; and a power supply 106 configured to supply power to the operation unit; and a connection cord 109 configured to electrically interconnect a first shoe care device of the two or more shoe care devices and a second shoe care device of the two or more shoe care devices such that power from the power supply of the first shoe care device is supplied to the power supply of the second shoe care device (figure 4). 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 26-29 and 32-36 are rejected under 35 U.S.C. 103 as being unpatentable over Chappell. Chappell discloses the claimed invention, as rejected above, except for the claimed flap spring, movable bracket, or push ribs. It would have been an obvious matter of design choice to recite those features, since the teachings of Chappell would perform the invention, as claimed regardless of those features and applicants have not claimed or specified the criticality of those features as being necessary for patentability. Claims 38-40 are rejected under 35 U.S.C. 103 as being unpatentable over Eichten in view of Chappell. Eichten discloses the claimed invention, as rejected above, except for the claimed electrical inlet/outlet, plural connectors, or cable. Eitchten discloses those features, as discussed in the first anticipatory rejection above. It would have been obvious to one skilled in the art to combine the teachings of Chappell with the teachings Eichten for the purpose of providing electrical power to a shoe care device. Furthermore, Eichten in view of Chappell discloses the claimed invention, except for the claimed flap spring, movable bracket, or push ribs. It would have been an obvious matter of design choice to recite those features, since the teachings of Eichten in view of Chappell would perform the invention, as claimed regardless of those features and applicants have not claimed or specified the criticality of those features as being necessary for patentability. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Other prior art references cited with this application, may teach one or more claim features, but do not rise to a level of anticipation, obviousness, and/or double patenting such that a rejection would be proper or reasonable under current Office practice and procedure. References A, B, C, N, O, cited with this action are patent publications from the same inventive entity. References D, E, F, G, H, I, J, K, cited with this action teach shoe care type devices.
