Office Action

§102 §103 §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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 12/17/25 has been entered. Response to Arguments Applicant amended in an After Final Response (12/11/25), however, the amendments appear to broaden the claims such that a new rejection is merited. 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. Claim 11 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. The limitation “corresponding to the same opening angle between the door and the case” is not understood. The apparatus appears to travel through a large angular range and the purported perpendicular distances and third angle and fourth angle change relative to the opening angle. It is not clear how the claim can be evaluated. 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. Claim(s) 1-2 and 12-14 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Squire, U.S. Patent 2,867,839. Regarding Claim 1, Squire teaches: a case (see below), defining a receiving space (see below) having an opening (see below); a door (see below), configured to block the opening; and a hinge assembly (see below), disposed body at a pivot side of the case and configured to pivotally connect the case to the door (Figs. 1-4); wherein the door has an inner edge (see below) and an outer edge (see below) at the pivot side, the door has a first reference plane (see below) and a second reference plane (see below); when the door is in a closed state relative to the case, the inner edge is located on and extend along the first reference plane, and the first reference plane is parallel to a plane in which the opening is located; when the door is in the closed state relative to the case, the outer edge is located on and extend along the second reference plane, and the second reference plane is perpendicular to the plane in which the opening is located, the first reference plane and the second reference plane stay stationary with respect to the case while the door is being opened with respect to the case (see below); a first hinge point (15) and a second hinge point (14) are formed on the hinge assembly; the second hinge point, compared to the first hinge point, is located further away from the outer edge; the hinge assembly comprises an outer shaft (15) and an inner shaft (14) arranged in the case, and an outer slot (26) and an inner slot (27) defined on the door, the outer slot and the outer shaft engages with each other to form the first hinge point at a center of the outer shaft, the inner slot and the inner shaft engages with each other to form the second hinge point at a center of the inner shaft; a first perpendicular line (First PL below) is generated from the center of the outer shaft to the outer edge; the (second PL below) is generated from the center of the outer shaft to the inner edge; the center of the outer shaft has a second perpendicular distance, along the second perpendicular line, to the inner edge; a third angle is generated between the first perpendicular line and the first reference plane, a fourth angle is generated between the second perpendicular line and the first reference plane; when the door is being opened from the closed state to a position of a first opening angle relative to the case, each of the first perpendicular distance and the second perpendicular distance is gradually decreased, the third angle is within a range of 0 degrees to 90 degrees and is gradually decreased, and the fourth angle is in a range of 0 degrees to 90 degrees and is gradually increased (see figs. 1-4 in light of annotated drawing); in process of the door being opened from the closed state to a maximum opening angle, the outer slot and the inner slot move together with the door such that at beginning of movement, the outer shaft is located at first end of the outer slot, the inner shaft is located at first end of the inner slot, at end of the movement, the outer shaft is located at second end of the outer slot, the inner shaft is located at second end of the inner slot, and a position of the outer shaft relative to the outer slot changes from the first end of the outer slot to the second end of the outer slot (see figs. 1 and 4). PNG media_image1.png 460 522 media_image1.png Greyscale Regarding Claim 2, Squire teaches: as an opening angle between the door and the case being increased by each unit of angle, a change in the first perpendicular distance is gradually increased; and a change in the second perpendicular distance is gradually decreased (see figs. 1-3 in light of annotated drawing above). Regarding Claims 12-13, see drawing selections below (with inner shaft 14) which satisfy the limitations as claimed. Examiner notes that the “inner edge” is an element of the door and therefore will change position from the closed position to the open position. PNG media_image2.png 352 346 media_image2.png Greyscale PNG media_image3.png 342 361 media_image3.png Greyscale Regarding Claim 14, see rejection of Claim 1 and note that the “first movement direction” and “second movement direction” are equivalents to the “first perpendicular line” and the “second perpendicular line”. 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(s) 3-8 and 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Squire ‘839. Regarding Claim 3, Squire is silent with regard to these relative dimensions being within the claimed ranges. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to provide the Squire device with the claimed dimensions because door thickness will vary depending on the application and positioning the shafts appropriately relative to the thickness of the door is well within the ordinary skill of one in the art. Furthermore, applicant has not provided any criticality for the claimed dimensions and it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144.05 [R-5]. Regarding Claim 4, Squire is silent with regard to the claimed angles being swept through by the claimed structures. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to provide the Squire device with the claimed angles because the ultimate opening angle can be selected from a wide variety of desired angles depending upon the application. Furthermore, applicant has not provided any criticality for the claimed angles and it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144.05 [R-5]. Regarding Claim 5, the claims set forth dimensions related by a mathematical process, but still set forth a range since they are based on the third angles which changes as the door is opened or closed. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to provide the Squire device with the claimed dimensions because the door thickness is a common design choice depending on the application and selecting the remaining dimensions to satisfy the kinematic requirements is well within the ordinary skill of those in the art and, furthermore, applicant has not provided any criticality for the claimed angles and it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144.05 [R-5]. Regarding Claim 6, it appears to be inherent that the claimed product would increase is constant or gradually decreasing while the door is opened. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to provide the Squire device with the claimed dimensions because the door thickness is a common design choice depending on the application and selecting the remaining dimensions to satisfy the kinematic requirements is well within the ordinary skill of those in the art and, furthermore, applicant has not provided any criticality for the claimed angles and it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144.05 [R-5]. Regarding Claim 7, the claims set forth dimensions related by a mathematical process, but still set forth a range since they are based on the third angles which changes as the door is opened or closed. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to provide the Squire device with the claimed dimensions because the door thickness is a common design choice depending on the application and selecting the remaining dimensions to satisfy the kinematic requirements is well within the ordinary skill of those in the art and, furthermore, applicant has not provided any criticality for the claimed angles and it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144.05 [R-5]. Regarding Claim 8, it appears to be inherent that the claimed product would increase is constant or gradually decreasing while the door is opened. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to provide the Squire device with the claimed dimensions because the door thickness is a common design choice depending on the application and selecting the remaining dimensions to satisfy the kinematic requirements is well within the ordinary skill of those in the art and, furthermore, applicant has not provided any criticality for the claimed angles and it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation. See MPEP 2144.05 [R-5]. Regarding Claim 11, see 112 rejection above, Examiner cannot determine what is intended to be claimed by these limitations. However, it appears that these limitations can be satisfied by one of the angles through which the prior art opens as set forth in the rejection of Claim 1.
