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 . Claim Rejections - 35 USC § 102 1. 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. 2. Claims 1, 3-9, 11-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CN112282547A (XIA, using US 2022/0259904 A1 for translation). With respect to claim 1, XIA shows a box device, comprising: a box body (10, Fig.1), internally defining an accommodating space with an opening; a door body (20, Fig.1), configured to block the opening; and a hinge assembly (30, Fig.4, Fig.5), disposed on a pivoting side of the box body (Fig.6) and pivotally connecting the box body (10) to the door body (20); wherein the hinge assembly comprises a first connecting member (31, FIg.5) and a second connecting member (32, FIg.5), the first connecting member (31) is disposed on the box body, and the second connecting member (32, FIg.5) is disposed on the door body; the first connecting member (31) is at least provided with a first sliding shaft (311) and a second sliding shaft (312), and the second connecting member (32) is at least provided with a first sliding rail (321, Fig.7) and a second sliding rail (322); the first sliding shaft (311) is connected to the first sliding rail (321) and is able to move along the first sliding rail (Fig.7-Fig.19), and the second sliding shaft (312) is connected to the second sliding rail (322) and is able to move along the second sliding rail (322); and wherein the first sliding rail (321) linearly extends (FIg.7), and the second sliding rail (322) extends along an ellipse (see annotated figure below); when the door body (20) blocks the opening (Fig.6), the first sliding rail (321) tilts relative to a plane where the opening is located (FIg.7-Fig.19), a part of the second sliding rail (322) away from the box body is away from the pivoting side relative to the first sliding rail (Fig.7), so that the door body (20) moves towards a target side of the box body (10, Fig.8, sections 0064 and 0065) during a process from blocking the opening by the door body (Fig.6) to opening the door body relative to the box body (Fig.8, door 20 moves from pivot side P towards opposite side when moved from position in figure 6 to figure 8; sections 0064 and 0065 of US PGPUB); and the opening comprises two opposite sides (Fig.6), the pivoting side (P, Fig.1) is disposed on one of the two opposite sides (Fig.1), and the target side is disposed on the other of the two opposite sides (other side); wherein a center of the ellipse (see annotation below) is located on the first sliding rail (321, see annotated figure below), and the first sliding shaft (311) and the second sliding shaft (312) are away from the opening relative to the center of the ellipse when the door body blocks the opening (Fig.6, Fig.7, annotation below). PNG media_image1.png 258 350 media_image1.png Greyscale With respect to claim 3, wherein the second sliding rail (322) bends along a direction close to the box body (Fig.6) when the door body blocks the opening. With respect to claim 4, wherein the second sliding rail (322) bends along a direction away from the box body (at portion at L1 in figure 7) when the door body blocks the opening (Fig.6). With respect to claim 5, wherein the second sliding rail (322) extends along a direction close to the pivoting side (at L2, FIg.7) and the direction close to the box body when the door body blocks the opening (Fig.6, Fig.7). With respect to claim 6, wherein the first sliding rail (321) extends along a direction close to the pivoting side (P, at A2, Fig.7) and a direction away from the box body (at A1, FIg.7) when the door body blocks the opening (Fig.7). With respect to claim 7, wherein the first sliding rail (321) extends along a direction (at A1, Fig.7) close to the target side and a direction away from the box body when the door body blocks the opening (Fig.7). With respect to claim 8, wherein an end surface of the door body facing the hinge assembly comprises an inner edge (at 22 in Fig.6) and an outer edge (at 23 in FIg.6), the inner edge and the outer edge are disposed at intervals along a first direction (X, Fig.6) and extend along a second direction (Y, Fig.6), the first direction (X) is perpendicular to the second direction (Y, FIg.6), and the inner edge is close to the box body (10) relative to the outer edge when the door body blocks the opening (Fig.6). With respect to claim 9, wherein the end surface of the door body facing the hinge assembly further comprises a side edge (at 24, FIg.6), the inner edge is connected to the outer edge by the side edge (24, Fig.6), and the side edge extends along the first direction (X). With respect to claim 11, XIA shows wherein the second sliding rail (322) where the second sliding shaft (312) is located has a tangent (P2, see annotation below), and an included angle between the first rail (at P1, see figure below) and the tangent (P2) is greater than or equal to 10 degrees. PNG media_image2.png 380 428 media_image2.png Greyscale With respect to claim 12, wherein the second sliding rail (322) intersects with a major axis of the ellipse (solid axis below) at an inflection point (see figure below). PNG media_image3.png 258 352 media_image3.png Greyscale With respect to claim 13, wherein the second sliding rail (322) has a target point (see annotation above), and the target point is located on a side of a minor axis (vertical dashed line axis in annotated figure above) of the ellipse facing the inflection point (see figure above). With respect to claim 14, wherein an included angle between the major axis of the ellipse and a connecting line (see annotation above) between the target point and the inflection point is greater than or equal to 10 degrees (see angle between the major axis and connecting line above). With respect to claim 15, wherein the second connecting member (32) defines a reference circle (see annotation below, green circle outside of the ellipse), a center of the reference circle is located on a center line (see annotation below) of the first sliding rail (321), and a center of the ellipse coincides with the center of the reference circle (see annotation below). PNG media_image4.png 258 350 media_image4.png Greyscale Claim Rejections - 35 USC § 103 3. 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. 4. Claims 10, 16-21 are rejected under 35 U.S.C. 103 as being unpatentable over CN112282547A (XIA) alone. With respect to claim 10, XIA shows wherein the first direction (X) is perpendicular to the plane where the opening is located however XIA doesn’t explicitly teach the minimum distances from any one of the first sliding rail and the second sliding rail to the inner edge, the outer edge, and the side edge are all greater than or equal to 6 mm. It would have been obvious matter of design choice to make the minimum distance greater than or equal to 6mm, in order to provide a door hinge that allows the door to rotate at a desirable distance and angle and since change in size is generally recognized as being within the level of ordinary skill in the art. With respect to claim 16, XIA shows wherein the side edge (at 24, Fig.6) is perpendicular to the plane where the opening is located, a radius of the reference circle is defined as R, a distance from the center of the reference circle to the side edge is defined as N, and XIA shows the radius (R ) is less than distance from the center of the reference circle (N) to the side edge (24, FIg.6) but doesn’t explicitly teach that that is less than 100 mm. It would have been obvious matter of design choice to make the distance (N) less than or equal to 100 mm, in order to construct a hinge with sliding rails and shafts at a desired distance from the side edge of the door to allow the door to rotate at a desirable distance and angle and since such a modification would involve a mere change in size which is generally recognized as being within the level of ordinary skill in the art. With respect to claim 17, XIA teaches wherein a radius of the reference circle is defined as R, a length of the side edge (at 24, FIg.6) in the first direction (X direction) is defined as D, a distance from the center of the reference circle to the outer edge is defined as W, but doesn’t explicitly teach R<W<(1/2)D. It would have been an obvious matter of design choice to make R<W<(1/2)D, in order to provide a hinge with slide rails and shafts at a desirable distance from the side edge and outer edge of the door to allow the door to rotate at a desirable distance and angle and since such a modification would involve a mere change in size which is generally recognized as being within the level of ordinary skill in the art. With respect to claim 18, XIA shows wherein the side edge (at 24, Fig.6) is perpendicular to the plane where the opening (at 14, FIg.6) is located, a distance from the center of the reference circle to the side edge is defined as N, but doesn’t show that 15 mm<N<100 mm. It would have been an obvious matter of design choice to make the distance (N) from the center of the reference circle to the side edge 15 mm<N<100 mm, in order to provide a hinge a desirable distance from the side edge of the door to allow the door to rotate at a desirable distance and angle and since such a modification would involve a mere change in size which is generally recognized as being within the level of ordinary skill in the art. With respect to claim 19, XIA shows wherein a radius of the reference circle is defined as R, a length of the side edge in the first direction is defined as D, a distance from the center of the reference circle to the outer edge is defined as W, but doesn’t explicitly disclose R<W<D. It would have been obvious matter of design choice to make R<W<D, in order to provide a hinge at a desirable distance from the side edge and outer edge of the door to allow the door to rotate at a desirable distance and angle and since such a modification would involve a mere change in size which is generally recognized as being within the level of ordinary skill in the art. With respect to claim 20, XIA shows the second connecting member (32) defines a reference circle, a center of the reference circle is located on a center line of the first sliding rail (see drawing above for claim 15), and a center of the ellipse coincides with the center of the reference circle (see annotation above for Fig.15); a length of the door body in the first direction (X) is defined as H; a length of the door body in the second direction (Y) is defined as L; a radius of the reference circle is defined as R, and R=(1/3)H; and a minimum distance from the reference circle to the outer edge is defined as M. XIA doesn’t disclose 35 mm<H<100 mm, 300 mm<L<700 mm, R=(1/3)H, and 0 mm<M<15 mm. It would have been obvious matter of design choice to make 35 mm<H<100 mm, 300 mm<L<700 mm, R=(1/3)H, and 0 mm<M<15 mm, in order to provide a desirable door body size and hinge a desirable distance from the edges of the door body to allow the door to rotate at a desirable distance and angle and since such a modification would involve a mere change in size which is generally recognized as being within the level of ordinary skill in the art. With respect to claim 21, XIA shows wherein the first sliding rail (321) extends along a first reference line (see annotation below), the second connecting member (32) defines a second reference line (see annotated Fig.7 below), and a starting point of the second sliding shaft (312, FIg.7) is located on an intersection point of the ellipse and the second reference line (see annotated figure below). PNG media_image5.png 258 350 media_image5.png Greyscale With respect to claim 21, XIA doesn’t explicitly disclose an arbitrary point (x,y) of the ellipse in a coordinate system satisfies the relationship X= M/sin(6)*cos(90°-a'-0)-R*sin(a'), y=M/sin(6)*sin(90°-a'-0); where X is a coordinate value of the arbitrary point on a first coordinate axis X, y is a coordinate value of the arbitrary point on a second coordinate axis Y, M is a coordinate absolute value of the starting point of the second sliding shaft on the first coordinate axis X, a' is an opening angle of the door body relative to the box body, and 0 is an angle between the first reference line and the second reference line. It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to make an arbitrary point (x,y) of the ellipse have the relationship of x= M/sin(6)*cos(90°-a'-0)-R*sin(a'), y=M/sin(6)*sin(90°-a'-0) since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. Response to Arguments Applicant's arguments filed 11/26/2025 have been fully considered but they are not persuasive. Applicant argued that Xia shows the second sliding shaft 312 is close to the opening relative to the center of ellipse when the door body blocks the opening. The examiner respectfully disagrees. As discussed in the previous rejection for claim 2, the examiner was using the second annotated figure of Fig.7 provided, (also see figure below) to reject previous claim 2 which represent a second type of ellipse. As clearly shown in the figure below, the first shaft 311 and the second shaft 312 are both away from the opening of the box (see the vertical line below labeled “opening”) relative to the center of the ellipse (as shown in the figure below, the shafts 311 and 312 are located outside the center line that extends through the center of the ellipse in the direction away from the opening of the box body) when the door body blocks the opening (FIg.6, Fig.7). PNG media_image6.png 263 352 media_image6.png Greyscale Conclusion THIS ACTION IS MADE FINAL. 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.
