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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 09/03/2026 has been entered. Specification objections in the Office action of 08/042026 are withdrawn. 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, 3 and 8 is/are rejected under 35 U.S.C. 102 (a) (1) as being anticipated by D1 (Boco Boddecker, DE 203 13 556). For claim 1, D1 discloses, in Figures 1-8, a key cylinder device (10) for a vehicle door, the key cylinder device comprising: a key cylinder turnable between an operation position at which a door lock device can be switched to a locked state or an unlocked state and a non-operation position at which the door lock device cannot be switched (P3, para. [5], Figures 1-3, 6.); a turning member (19) attached to the key cylinder and turnable integrally with the key cylinder (P4, para. [1-2]); and a pulling member (25, 36) having one end (26) connected to the turning member (19) and configured to transmit an operating force of the key cylinder by key operation to the door lock device via the turning member (P4, para. [1-2]); wherein the turning member (19) includes a winding portion (the portion, on which the cable winds, includes 29, 33) around which the pulling member (cable 36) is windable by turning of the key cylinder from the non-operation position to the operation position (Figures 3, 6.); and wherein the winding portion (29, 33) includes a concave groove (29, Figures 2-3) formed in an arc shape (As shown below, Figure 3) and defined by a pair of sidewalls (As shown below in Figure 8) and a groove bottom (As shown below in Figure 3 and 8), wherein the pair of sidewalls extends radially outward from the groove bottom relative to a rotation axis (20, Figure 1) of the key cylinder (as shown below in Figure 2), each sidewall of the pair of sidewalls extending a same distance from the groove bottom (As shown below in Figure 8.)

For claim 8, D1 discloses the key cylinder device for a vehicle door according to claim 1, wherein the winding portion (29, 33) extends in a circumferential direction around the rotation axis of the key cylinder (Figure 2.) 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. 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. Claim(s) 4 and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over D1 (Boco Boddecker, DE 203 13 556) in view of D2 (Knott, US 4,080,812). For claim 4, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose wherein the key cylinder is disposed at a lower end portion of the vehicle door. D2 teaches, in Figures 1-7, a key cylinder lock 18 disposed at a lower end portion of the vehicle trunk door to facilitate the opening of the door to utilize the entire trunk space. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 to have the key cylinder disposed at a lower end portion of the vehicle door, as taught by D2 with a reasonable expectation of success of providing a way to use the entire trunk space. For claim 9, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose wherein the key cylinder is disposed at a lower end portion of the vehicle door. D2 teaches, in Figures 1-7, a key cylinder lock 18 disposed at a lower end portion of the vehicle trunk door to facilitate the opening of the door to utilize the entire trunk space. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 to have the key cylinder disposed at a lower end portion of the vehicle door, as taught by D2 with a reasonable expectation of success of providing a way to use the entire trunk space. Claim(s) 5-7, and 10-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over D1 (Boco Boddecker, DE 203 13 556) in view of D3 (Katagiri, et al., US Pub. App. 2012-0137743). For claim 5, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose wherein the key cylinder is disposed such that a key hole is directed to a lower side. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having the key hole directed to a lower side to protect the key hole. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a key cylinder is disposed such that a key hole is directed to a lower side, as taught by D3 with a reasonable expectation of success of protecting the key hole. For claim 6, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose comprising a cover configured to cover at least the key cylinder and suppress operation from outside. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having a pivotable shutter (cover) 4 to cover the key hole. The shutter 4 pivots to reveal the key hole only by pivoting the door handle beyond a certain limit (Para. [0050-0052]), thus protecting the key hole. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a cover configured to cover at least the key cylinder and suppress operation from outside, as taught by D3 with a reasonable expectation of success of protecting the key hole. For claim 7, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose comprising a cover configured to cover at least the key cylinder and prevent entering of water. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having longitudinal axis tilted such that the key hole faces the ground, and a pivotable shutter (cover) 4 to cover the key hole. The shutter 4 pivots to reveal the key hole only by pivoting the door handle beyond a certain limit (Para. [0050-0052]). Both the shutter and the tilting of key cylinder protect the key hole from elements. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a cover configured to cover at least the key cylinder and prevent entering of water, as taught by D3 with a reasonable expectation of success of protecting the key hole from elements. For claim 10, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose wherein the key cylinder is disposed such that a key hole is directed to a lower side. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having the key hole directed to a lower side to protect the key hole. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a key cylinder is disposed such that a key hole is directed to a lower side, as taught by D3 with a reasonable expectation of success of protecting the key hole. For claim 11, D1 discloses the key cylinder device for a vehicle door according to claim 3, but does not disclose wherein the key cylinder is disposed such that a key hole is directed to a lower side. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having the key hole directed to a lower side to protect the key hole. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a key cylinder is disposed such that a key hole is directed to a lower side, as taught by D3 with a reasonable expectation of success of protecting the key hole. For claim 12, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose comprising a cover configured to cover at least the key cylinder and suppress operation from outside. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having a pivotable shutter (cover) 4 to cover the key hole. The shutter 4 pivots to reveal the key hole only by pivoting the door handle beyond a certain limit (Para. [0050-0052]), thus protecting the key hole. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a cover configured to cover at least the key cylinder and suppress operation from outside, as taught by D3 with a reasonable expectation of success of protecting the key hole. For claim 13, D1 discloses the key cylinder device for a vehicle door according to claim 1, but does not disclose comprising a cover configured to cover at least the key cylinder and prevent entering of water. D3 teaches, in Figures 1-2, 4-12, and 14, a vehicle door with a key cylinder 5 having longitudinal axis tilted such that the key hole faces the ground, and a pivotable shutter (cover) 4 to cover the key hole. The shutter 4 pivots to reveal the key hole only by pivoting the door handle beyond a certain limit (Para. [0050-0052]). Both the shutter and the tilting of key cylinder protect the key hole from elements. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify D1 with a cover configured to cover at least the key cylinder and prevent entering of water, as taught by D3 with a reasonable expectation of success of protecting the key hole from elements.
