The mounting system also includes a perimeter suspension section coupled to the outer section and adapted to secure the electronic device to the mounting system, the perimeter suspension section including a spring portion provided around a periphery of the perimeter suspension section, the spring portion being adapted to isolate the electronic device from a shock force that may be applied to the mounting system. ## Claims ### Claim 1 A protective case for an electronic device, comprising: a front cover; a rear cover including a middle rear cover, an exterior rear cover, and a folding portion that connects the middle rear cover to the exterior rear cover; a spine portion that connects the front cover to the rear cover; and a mounting system comprising: an outer section having an inner surface and an outer surface, the inner surface adapted to face the electronic device when the electronic device is mounted in the mounting system; and a perimeter suspension section coupled to the outer section and adapted to secure the electronic device to the mounting system, the perimeter suspension section including a spring portion provided around a periphery of the perimeter suspension section, the spring portion adapted to isolate the electronic device from a shock force applied to the mounting system, wherein the mounting system is coupled to an attachment surface of the exterior rear cover. ### Claim 2 (depends on 1) The protective case of claim 1, wherein the mounting system is attached to the exterior rear cover by an adhesive disposed between the outer surface of the outer section and the attachment surface of the exterior rear cover. ### Claim 3 (depends on 1) The protective case of claim 1, wherein the outer section comprises: a central portion that is substantially planar, and an outer portion surrounding the central portion and being inclined relative to the central portion in a direction toward the inner surface of the outer section, wherein the perimeter suspension section is disposed on the inner surface of the outer section such that the spring portion is positioned adjacent to the outer portion of the outer section. ### Claim 4 (depends on 3) The protective case of claim 3, wherein the outer portion has a radius of curvature. ### Claim 5 (depends on 3) The protective case of claim 3, wherein the central portion is substantially coextensive with the electronic device secured in the mounting system. ### Claim 6 (depends on 1) The protective case of claim 1, wherein the perimeter suspension section is co-molded with the outer section. ### Claim 7 (depends on 1) The protective case of claim 1, wherein the spring portion comprises a plurality of voids extending only partially through a thickness of the perimeter suspension section. ### Claim 8 (depends on 7) The protective case of claim 7, wherein the voids have a shape selected from the group consisting of a circle, a triangle, a rectangle, a slit, a hexagon, an oval, and a trapezoid. ### Claim 9 (depends on 1) The protective case of claim 1, wherein the spring portion comprises a plurality of voids, wherein the voids comprise through holes extending through the entire thickness of the perimeter suspension section. ### Claim 10 (depends on 1) The protective case of claim 1, wherein the perimeter suspension section is disposed on the entire inner surface of the outer section such that when the electronic device is mounted in the mounting system, the electronic device does not contact the outer section. ### Claim 11 (depends on 1) The protective case of claim 1, wherein the outer section is composed of a rigid material. ### Claim 12 (depends on 11) The protective case of claim 11, wherein the perimeter suspension section is composed of an elastic material. ### Claim 13 (depends on 12) The protective case of claim 12, wherein the perimeter suspension section is co-molded with the outer section. ### Claim 14 (depends on 1) The protective case of claim 1, comprising a mount opening for attaching the mounting system to a case. ### Claim 15 (depends on 14) The protective case of claim 14, wherein the perimeter suspension section is disposed on the entire inner surface of the outer section, and wherein the outer section comprises a first opening and the perimeter suspension section comprises a second opening concentric with the first opening, the mount opening being formed by the first opening and the second opening. ### Claim 16 (depends on 1) The protective case of claim 1, further comprising: a plurality of device openings formed in the outer section to provide access to the electronic device. ### Claim 17 (depends on 1) The protective case of claim 1, wherein the mounting system comprises a flange adapted to secure the electronic device. ### Claim 18 (depends on 1) The protective case of claim 1, wherein the attachment surface is substantially coextensive with the exterior rear cover. ### Claim 19 (depends on 1) The protective case of claim 1, wherein the middle rear cover has a larger surface area than the exterior rear cover. ### Claim 20 (depends on 19) The protective case of claim 19, wherein the exterior rear cover has a first length measured in a first direction and the middle rear cover has a second length measured in the first direction, the second length being at least two times that of the first length. ### Claim 21 (depends on 1) The protective case of claim 1, wherein the outer section is composed of a polycarbonate material. ### Claim 22 (depends on 1) The protective case of claim 1, wherein the perimeter suspension section is composed of a silicone or a thermoplastic polyurethane material. ### Claim 23 (depends on 1) The protective case of claim 1, wherein, when the protective case is in an open state, the exterior rear cover is adapted to be opened at various angles with respect to the front cover. ### Claim 24 (depends on 1) The protective case of claim 1, wherein the electronic device is a tablet.
