## Abstract

A case for a mobile device, including first, second, third, and fourth sides, each with inside and outside surfaces opposite to each other. The inside surfaces of the first and second sides face each other. The inside surface of the third and fourth sides faces each other. The first and second sides are arranged between the third and fourth sides, and the third and fourth sides are arranged between the first and second sides, so that the four sides form at least part of a frame configured to surround a periphery of the mobile device. At least one of the inside surfaces of the first, second, third, and fourth sides includes triangular protrusions that have a triangular cross section and extend toward the inside of the case, so that an apex of each of the triangular protrusions contacts the mobile device when it is arranged inside the case.

## Claims

### Claim 1

A case for a mobile device, comprising:
a first side with an inside surface and an outside surface opposite to the inside surface;
a second side with an inside surface and an outside surface opposite to the inside surface;
a third side with an inside surface and an outside surface opposite to the inside surface; and
a fourth side with an inside surface and an outside surface opposite to the inside surface;
wherein the inside surface of the first side faces toward the inside surface of the second side;
wherein the inside surface of the third side faces toward the inside surface of the fourth side;
wherein the first and second sides are arranged between the third and fourth sides, and the third and fourth sides are arranged between the first and second sides, so that the first, second, third, and fourth sides form at least part of a frame configured to surround a periphery of the mobile device when the mobile device is arranged inside the case;
wherein at least one of the inside surfaces of the first, second, third, and fourth sides includes triangular protrusions that have a triangular cross section and extend toward the inside of the case, so that an apex of each of the triangular protrusions contacts the mobile device when it is arranged inside the case.

### Claim 2 (depends on 1)

The case for a mobile device according to claim 1;
wherein at least two of the inside surfaces of the first, second, third, and fourth sides include the triangular protrusions.

### Claim 3 (depends on 1)

The case for a mobile device according to claim 1;
wherein at least three of the inside surfaces of the first, second, third, and fourth sides include the triangular protrusions.

### Claim 4 (depends on 1)

The case for a mobile device according to claim 1;
wherein the inside surface of the first side is connected to the inside surface of the third side to form a first corner, the first corner having an inside surface that includes at least one of the triangular protrusions.

### Claim 5 (depends on 4)

The case for a mobile device according to claim 4;
wherein the inside surface of the second side is connected to the inside surface of the third side to form a second corner, the second corner having an inside surface that includes at least one of the triangular protrusions.

### Claim 6 (depends on 4)

The case for a mobile device according to claim 4;
wherein the inside surface of the second side is connected to the inside surface of the fourth side to form a third corner, the third corner having an inside surface that includes at least one of the triangular protrusions.

### Claim 7 (depends on 1)

The case for a mobile device according to claim 1, further comprising:
a rear side with an inside surface that faces toward, and an outside surface that faces away from, the mobile device when it is arranged inside the case, the rear side being connected to the first, second, third, and fourth sides to form a pocket configured to hold the mobile device.

### Claim 8 (depends on 7)

The case for a mobile device according to claim 7;
wherein outside surface of the rear side is formed by a first layer comprising a first material; and
wherein the inside surfaces of the first, second, third, and fourth sides are formed by a second layer comprising a second material different from the first material.

### Claim 9 (depends on 8)

The case for a mobile device according to claim 8;
wherein the outside surfaces of the first, second, third, and fourth sides are formed by the first layer comprising the first material.

### Claim 10 (depends on 8)

The case for a mobile device according to claim 8;
wherein the inside surface of the rear side is formed by the first layer comprising the first material; and
wherein the inside surface of the rear side is configured to not touch the mobile device so that an air gap is created between the inside surface of the rear side and the mobile device when it is arranged inside the case.

### Claim 11 (depends on 10)

The case for a mobile device according to claim 10;
wherein the first material is translucent, transparent, or clear, so that the rear side of the mobile device can be seen through the rear side of the case when the mobile device is arranged inside the case.

### Claim 12 (depends on 8)

The case for a mobile device according to claim 8;
wherein the inside surface of the rear side is formed by the second layer comprising the second material.

### Claim 13 (depends on 12)

The case for a mobile device according to claim 12;
wherein both the first material and the second material are translucent, transparent, or clear, so that the rear side of the mobile device can be seen through the rear side of the case when the mobile device is arranged inside the case.

### Claim 14 (depends on 8)

The case for a mobile device according to claim 8;
wherein the first material comprises at least one material selected from the group consisting of hardened plastic materials, rigid or semi-rigid plastic materials, rigid rubber materials, polycarbonate materials, metals, alloys, para-aramid materials, wood, glass, mirror, quartz, and combinations thereof; and
wherein the second material comprises at least one material selected from the group consisting of thermoplastic elastomers (“TPEs”), thermoplastic polyurethane (“TPU”), silicone, rubber, and combinations thereof.

### Claim 15 (depends on 1)

The case for a mobile device according to claim 1;
wherein the triangular protrusions are arranged along the at least one inside surface in an array extending from a first end of the at least one inside surface adjacent to one of the first, second, third, and fourth sides to a second end of the at least one inside surface opposite to the first end and adjacent to another of the first, second, third, and fourth sides.

### Claim 16 (depends on 1)

The case for a mobile device according to claim 1;
wherein the triangular protrusions have a solid triangular cross section.

### Claim 17 (depends on 1)

The case for a mobile device according to claim 1;
wherein the apex of each of the triangular protrusions contacts a surface of the mobile device facing the at least one inside surface when the mobile device is arranged inside the case.
