Regarding claim 28, Fisher discloses a scaled composite structure according to claim 25, characterized in that the size and the shape of at least a given scale of the plurality of 3D scales is a function of a location of the given scale (e.g. knuckle support segment and endcap support segment) within the scaled composite structure (e.g. ¶128 and 145-146; Fig. 19) . Regarding claim 31, Fisher discloses a scaled composite structure according to Claim 25, characterized in that each of the plurality of 3D scales comprises a body portion (e.g. knuckle support segment) and a nose portion (e.g. end cap support segment) , wherein the nose portion is characterized as a front extension of each of the plurality of 3D scales which overlaps a preceding 3D scale in the scaled composite structure (e.g. ¶128 and 145-146; Fig. 19) .

Regarding claim 34, Fisher discloses a wearable protective device according to claim 33, characterized in that the wearable protective device further comprises at least one of a double-sided adhesive layer, a type of hydrogel adhesive layer, a silicone adhesive layer or a rubber adhesive layer on one side of the wearable protective device or a sleeve that is interlaced (e.g. cushioning of sleeve for a hand or finger) with the wearable protective device, for attaching to a skin of a wearer (e.g. ¶91-92, 127 and 129) . Regarding claim 35, Fisher discloses a method for designing and manufacturing a scaled composite structure, wherein the scaled composite structure comprises a plurality of three-dimensional (3D) scales that are attached to a flexible base layer arrangement, wherein the method comprises: determining, by using a data processing arrangement, a flexible base layer arrangement and a shape of the flexible base layer arrangement, based on at least one input parameter, at a limit of a range of motion to be applied to the scaled composite structure (e.g. ¶25, 102, 105 and 108-113; Fig. 18 -20 ) ; determining, by using the data processing arrangement, a size and a shape of each of the plurality of 3D scales that are arranged on the flexible base layer arrangement when curved to the limit of the range of motion, thereby determining a length of each of the plurality of 3D scales (e.g. ¶25, 102, 105 and 108-113; Fig. 18 -20 ) ; and manufacturing the scaled composite structure based on the size and the shape of each of the plurality of 3D scales that are arranged on the flexible base layer arrangement when curved to the limit of the range of motion, such that the scaled composite structure provides a mechanical interlocking effect when the limit of the range of motion is applied to the scaled composite structure and is flexible until each of the plurality of 3D scales interlock with each other (e.g. ¶25, 102, 105 and 108-113; Fig. 18 -20 ) .

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) 29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fisher as applied to the claim s above, and further in view of Dantus et al. U.S. PGPub 2017/0089779 (hereinafter “ Dantus ”) . Regarding claim 29, Fisher does not disclose the scales changing color when a force is applied. Dantus discloses a protective garment that change color when a force applied over the scaled composite structure exceeds a threshold value (e.g. ¶45) . At the time the invention was filed, it would have been obvious to a person of ordinary skill in the art to change the color of a protective garment when force is applied . One of ordinary skill in the art would have been motivated to do this to provide a visual indicator to the user that a dangerous level of impact has been sustained. Therefore, it would have been obvious to modify Fisher with Dantus to obtain the invention as specified in claim 29 . Claim(s) 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fisher as applied to the claim s above, and further in view of Howland U.S. PGPub 2016/0040963 (hereinafter “Howland”) . Regarding claim 30, Fisher discloses segments with a length and width (e.g. Fig. 1, 13 and 19-25) , but does not explicitly disclose the length and width of the segments being within 0.01 mm to 500 mm. Howland discloses a protective garment that has segments whose dimensions are between 0.01 mm to 500 mm (e.g. ¶2 and 52-54; Fig. 4D). At the time the invention was filed, it would have been obvious to a person of ordinary skill in the art to have the glove segments with dimensions that are between 0.01 mm to 500 mm . One of ordinary skill in the art would have been motivated to do this in order for the garment to move flexibly with the user while providing the desired protection . Therefore, it would have been obvious to modify Fisher with Howland to obtain the invention as specified in claim 30 . Allowable Subject Matter Claims 32, 39 and 43 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 32, the prior art of record does not disclose each scale being attached to the flexible base layer arrangement via a plurality of teeth provided at a surface of the scale facing towards the flexible base layer arrangement, wherein the plurality of teeth are arranged to penetrate through the flexible base layer arrangement to attach to a base plate. Regarding claim 39, the prior art of record does not disclose determining a diameter and a height of a plurality of teeth like structures in each of the plurality of 3D scales based on a degree of fineness and a thickness of the type of the flexible base layer arrangement, wherein the plurality of teeth like structures are configured to penetrate through the flexible base layer arrangement to attach the 3D scales to the flexible base layer arrangement. Regarding claim 43, the prior art of record does not disclose t he manufacturing of the scaled composite structure comprises: providing a flexible base layer arrangement; generating a bottom layer of at least one scale of the plurality of 3D scales; generating a plurality of teeth like structures projecting from the bottom layer; adding a first layer above the bottom layer; and generating a top layer of the at least one scale of the plurality of 3D scales on top of the first layer.
