The protective case also includes a geometry seal located inside of the cavity, where the geometry seal is configured to form a lower waterproof seal with the sidewall section and the backing. Furthermore, the protective case also includes a top section, which forms an upper waterproof seal with the sidewall section and the geometry seal, thereby allowing the protective case to provide a waterproof seal around the mobile device. ## Claims ### Claim 1 A protective case for a mobile device comprising: a backing with at least two backing grooves on a face of the backing, each backing groove receiving one of at least two protrusions of a waterproof seal, the at least two protrusions being parallel to each other; a contiguous, one-piece sidewall section comprising four external sides, the contiguous, one-piece sidewall attached to the backing via a hinge; a cavity defined by the contiguous, one-piece sidewall section and the backing; a four-sided, rectangular waterproof seal, the waterproof seal encircling a perimeter of the cavity, the waterproof seal comprising the at least two protrusions; and the waterproof seal sealing the cavity, the sealing comprising preventing a liquid from entering the cavity when compression is applied to the waterproof seal, the compression being caused by insertion of the mobile device into the cavity. ### Claim 2 (depends on 1) The protective case of claim 1, in which the waterproof seal further comprises one or more protrusions into the cavity that provide shock protection for the mobile device. ### Claim 3 (depends on 2) The protective case of claim 2, further including a transparent cover accessible to a touch screen of the mobile device. ### Claim 4 (depends on 1) The protective case of claim 1, in which the sidewall section comprises one or more openings, the waterproof seal being exposed through the openings such that one or more buttons on the mobile device may be pressed through the one or more openings via contact with the waterproof seal. ### Claim 5 (depends on 4) The protective case of claim 4, in which the waterproof seal further comprises a headphone port opening, allowing a headphone plug to be inserted through an opening in the sidewall into the mobile device. ### Claim 6 (depends on 5) The protective case of claim 5, further comprising a headphone seal plug insertable into the headphone port opening, the headphone seal plug forming a waterproof seal when inserted into the headphone port opening. ### Claim 7 (depends on 3) The protective case of claim 3, in which the transparent cover is integrated into a top section. ### Claim 8 (depends on 3) The protective case of claim 3, in which the transparent cover is a separate element affixed to a top section. ### Claim 9 (depends on 1) The protective case of claim 1, in which the protective case is waterproof for greater than two meters depth. ### Claim 10 (depends on 1) The protective case of claim 1, in which the waterproof seal is an h-seal. ### Claim 11 A method for making a protective case for a mobile device comprising: providing a backing with at least two backing grooves on a face of the backing, each backing groove receiving one of at least two protrusions of a waterproof seal, the at least two protrusions being parallel to each other; providing a contiguous, one-piece sidewall section comprising four external sides, the contiguous, one-piece sidewall section attached to the backing via a hinge; providing a cavity defined by the contiguous, one-piece sidewall section and the backing; providing a four-sided, rectangular waterproof seal, the waterproof seal encircling a perimeter of the cavity, the waterproof seal comprising the at least two protrusions; and sealing of the cavity by the waterproof seal, the sealing comprising preventing a liquid from entering the cavity when compression is applied to the waterproof seal, the compression being caused by insertion of the mobile device into the cavity. ### Claim 12 (depends on 11) The method for making a protective case of claim 11, further comprising providing shock protection for the mobile device using one or more protrusions into the cavity attached to the waterproof seal. ### Claim 13 (depends on 11) The method for making a protective case of claim 11, in which the protective case comprises a transparent cover permit access accessible to a touch screen of the mobile device. ### Claim 14 (depends on 11) The method for making a protective case of claim 11, in which the sidewall section comprises one or more openings, further comprising situating the waterproof seal so that the waterproof seal is exposed through the openings such that one or more buttons on the mobile device may be pressed through the one or more openings via contact with the waterproof seal. ### Claim 15 (depends on 14) The method for making a protective case of claim 14, in which the waterproof seal further comprises an headphone port opening, allowing a headphone plug to be inserted through an opening in the sidewall into the mobile device. ### Claim 16 (depends on 15) The method for making a protective case of claim 15, further comprising inserting a headphone seal plug into the headphone port opening, forming a waterproof seal. ### Claim 17 (depends on 13) The method for making a protective case of claim 13, further comprising integrating the transparent cover into a top section. ### Claim 18 (depends on 13) The method for making a protective case of claim 13, in which the transparent cover is a separate element affixed to a top section. ### Claim 19 (depends on 11) The method for making a protective case of claim 11, in which the protective case is waterproof for greater than two meters depth. ### Claim 20 (depends on 11) The method for making a protective case of claim 11, in which the geometry seal is an h-seal.
