The elastomeric shell is received in the frame and has an outer surface, an inner surface opposite the outer surface and configured for receiving the mobile device, and a rim extending between the outer surface and the inner surface. The inner surface forms inner projections each having an inner extremity extending toward an inside of the elastomeric shell and each being configured for contact with the mobile device when arranged in the inner surface. The outer surface forms outer projections defining respective outer projection extremities and forms outer troughs extending between the outer projections and defining outer trough extremities. The outer projections extend toward a frame inner perimeter of the frame such that each of the outer trough extremities is spaced further from the frame than adjacent ones of the outer projection extremities. ## Claims ### Claim 1 A protective case, the protective case comprising: a frame comprising a planar frame base from which a plurality of frame sides extend thereby defining a frame cavity; and an elastomeric shell comprising a elastomeric shell cavity defined by a shell base from which a plurality of adjacent shell sides extend upwardly, wherein the plurality of adjacent shell sides comprise a shell inner surface and a shell outer surface, wherein the shell inner surface comprises a plurality of inner projections disposed at approximately even intervals, and the shell outer surface comprises a plurality of outer projections disposed at approximately even intervals, and a shell rim extending between the shell outer surface and the shell inner surface, wherein the elastomeric shell cavity is adapted to enclose a rear surface and a periphery of a mobile device; wherein the frame cavity is adapted to enclose the shell cavity such that the frame base is in contact with the shell base and the outer projections contact the frame cavity; wherein the plurality of inner projections each comprise a deformable inner extremity in the shape of a triangular ridge, wherein an apex of each triangular ridge is oriented toward the shell cavity such that the apex is adapted to contact the periphery of the mobile device; wherein the outer projections contact the frame sides and comprise an outer projection extremity extending outwardly from the shell cavity; wherein the inner projections and outer projections alternate along a length of each shell side. ### Claim 2 (depends on 1) The case according to claim 1, wherein a thickness of the elastomeric shell along at least a portion of a cross-section of the elastomeric shell cavity that includes one of the outer projections is uniform. ### Claim 3 (depends on 1) The case according to claim 1, wherein the frame further comprises a frame rim, and wherein the elastomeric shell further comprises a shell bezel defining the shell rim, wherein the shell bezel extends over at least a portion of the frame rim. ### Claim 4 (depends on 3) The case according to claim 3, further comprising an adhesive channel disposed between opposing portions of the frame rim and the shell bezel. ### Claim 5 (depends on 1) The case according to claim 1, wherein the frame further comprises a frame rim, the case further comprising an elastomeric bezel extending from the frame rim and extending over at least a portion of the shell rim. ### Claim 6 (depends on 5) The case according to claim 5, wherein the frame further comprises a plurality of frame holes adjacent the frame rim, wherein portions of the elastomeric bezel extend through the plurality of frame holes. ### Claim 7 (depends on 6) The case according to claim 6, wherein opposing portions of the shell rim and the elastomeric bezel are spaced apart a greater distance than portions of the elastomeric shell adjacent to the shell rim are spaced from opposing portions of the elastomeric bezel to define an adhesive channel, the case further comprising an adhesive extending along the adhesive channel and bonding the elastomeric bezel to the shell rim. ### Claim 8 (depends on 1) The case according to claim 1, wherein a tangential plane tangential to at least three of the outer projections defines spaced-apart and collinear segments. ### Claim 9 (depends on 8) The case according to claim 8, wherein the frame further comprises a frame inner surface having a frame planar portion, and wherein at least a majority of at least one of the segments defined by the outer projection extremities lies in abutment with the frame planar portion. ### Claim 10 (depends on 1) The case according to claim 1, wherein either one or both of the frame and the elastomeric shell is translucent, transparent, or clear. ### Claim 11 (depends on 1) The case according to claim 1, wherein the frame base includes an artifact opening extending through the frame base, the case further comprising a marking artifact attached to the frame base and protruding through the frame base through the artifact opening to expose portions of the marking artifact. ### Claim 12 (depends on 1) The case according to claim 1, wherein the elastomeric shell defines a button cover configured for covering a button of a mobile device when the mobile device is received in the case, the case further comprising a rigid button cap covering the button cover and extending through the frame. ### Claim 13 (depends on 12) The case according to claim 12, wherein the button cap is translucent, transparent, or clear and includes a print visible to the naked eye through the button cap. ### Claim 14 (depends on 1) The case according to claim 1, wherein a gap exists between adjacent frame sides such that each frame side is adapted to flex outwardly relative to the frame base. ### Claim 15 A protective case comprising: a frame, comprising: a frame base characterized by a frame perimeter having a plurality of frame perimeter edges, the frame perimeter having a shape corresponding to a periphery of a mobile device; a plurality of frame sides extending away from each frame perimeter edge in a first direction, such that the frame base conforms to a rear surface of the mobile device and the plurality of frame sides define a frame cavity; a shell comprising an elastomeric material, further comprising: a shell base having a shape congruent with the frame perimeter; a plurality of shell sides extending from the shell base in the first direction, such that the shell base and the plurality of shell sides define a shell cavity that is congruent with the frame cavity; wherein each of the plurality of shell sides comprises an interior surface and an exterior surface, and a plurality of channels disposed at regular intervals along the length of each shell side, wherein each of the plurality of channels extends in the first direction, wherein each of the plurality of channels is triangular in cross section such that the apex of each channel is oriented inwardly towards the cavity such that the interior surface of the shell side corresponding to the apex is adapted to contact the periphery of the mobile device, wherein contact between the exterior surface of the shell side adjacent to each channel and the proximate frame side defines a prismatic void between the shell side and the proximate frame side. ### Claim 16 (depends on 15) The protective case according to claim 15, wherein a gap exists between adjacent frame sides, such that each of the plurality of frame sides are adapted to flex outwardly from each frame perimeter edge.
