Official abstract text for this publication.
An expandable device for attachment to a foldable electronic device having first and second surfaces includes a button and a pivotable frame member. The button has a top side, a bottom side, and a coupling portion and is movable between an expanded configuration and a collapsed configuration. The pivotable frame member is operably coupled to the button and includes a device coupling portion that engages a portion of the foldable electronic device. The pivotable frame member is pivotable between a first configuration whereby the button is positioned along at least one of the first surface or the second surface of the foldable electronic device and a second configuration whereby the button is positioned away from the foldable electronic device.

What is claimed is: 1. An accessory for attachment to a mobile electronic device, the accessory configured to provide grip and kickstand functionality, the accessory comprising: a base member having a device-facing surface configured to detachably attach to a rear surface of the mobile electronic device or to a rear surface of a case of the mobile electronic device; a pivotable member coupled to the base member at a hinge portion, wherein the pivotable member extends from the hinge portion and is pivotable between at least a closed configuration and an open configuration, wherein the pivotable member comprises a base-facing surface and an opposite accessory-facing surface; and a grip detachably coupled to the accessory-facing surface of the pivotable member, wherein the grip is movable between an expanded configuration and a collapsed configuration, wherein at least a portion of the grip expands away from the accessory-facing surface of the pivotable member when moving from the collapsed configuration to the expanded configuration, and contracts towards the accessory-facing surface of the pivotable member when moving from the expanded configuration to the collapsed configuration. 2. The accessory of claim 1 , wherein the pivotable member is configurable as a kickstand for the mobile electronic device when in the open configuration. 3. The accessory of claim 1 , wherein the base-facing surface of the pivotable member faces the base member when the pivotable member is in the closed configuration. 4. The accessory of claim 3 , wherein the base-facing surface of the pivotable member further contacts the base member when the pivotable member is in the closed configuration. 5. The accessory of claim 1 , wherein the grip in the expanded configuration is configured to be grasped by a user to securely hold the mobile electronic device when the pivotable member is in the closed configuration. 6. The accessory of claim 1 , wherein the grip comprises a top side, a bottom side, and a coupling portion, and wherein the top side of the grip expands away from the accessory-facing surface of the pivotable member when moving from the collapsed configuration to the expanded configuration, and contracts towards the accessory-facing surface of the pivotable member when moving from the expanded configuration to the collapsed configuration. 7. The accessory of claim 1 , further comprising a securing mechanism configured to retain the pivotable member in the closed configuration. 8. An accessory for attachment to a mobile electronic device, the accessory configured to provide grip and kickstand functionality, the accessory comprising: a base member having a device-facing surface configured to detachably attach to a rear surface of the mobile electronic device or to a rear surface of a case of the mobile electronic device; a pivotable member coupled to the base member at a hinge portion, wherein the pivotable member extends from the hinge portion and is pivotable between at least a closed configuration and an open configuration, wherein the pivotable member comprises a base-facing surface and an opposite accessory-facing surface; and a grip detachably coupled to the accessory-facing surface of the pivotable member, wherein the grip is movable between an expanded configuration and a collapsed configuration, wherein the grip comprises an expandable mechanism which is configured to resiliently retain the grip in the closed configuration and expanded configuration, respectively. 9. The accessory of claim 8 , wherein the pivotable member is configurable as a kickstand for the mobile electronic device when in the open configuration. 10. The accessory of claim 8 , wherein the base-facing surface of the pivotable member faces the base member when the pivotable member is in the closed configuration. 11. The accessory of claim 10 , wherein the base-facing surface of the pivotable member further contacts the base member when the pivotable member is in the closed configuration. 12. The accessory of claim 8 , wherein the grip in the expanded configuration is configured to be grasped by a user to securely hold the mobile electronic device when the pivotable member is in the closed configuration. 13. The accessory of claim 8 , wherein at least a portion of the grip expands away from the accessory-facing surface of the pivotable member when moving from the collapsed configuration to the expanded configuration, and contracts towards the accessory-facing surface of the pivotable member when moving from the expanded configuration to the collapsed configuration. 14. The accessory of claim 8 , wherein the grip comprises a top side, a bottom side, and a coupling portion, and wherein the top side of the grip expands away from the accessory-facing surface of the pivotable member when moving from the collapsed configuration to the expanded configuration, and contracts towards the accessory-facing surface of the pivotable member when moving from the expanded configuration to the collapsed configuration. 15. The accessory of claim 8 , further comprising a securing mechanism configured to retain the pivotable member in the closed configuration. 16. A combination grip and kickstand accessory for attachment to a mobile electronic device, the accessory comprising: a base member having a device-facing surface configured to detachably attach to a rear surface of the mobile electronic device or to a rear surface of a case of the mobile electronic device; a kickstand member coupled to the base member at a hinge portion, wherein the kickstand member extends from the hinge portion and is pivotable between at least a closed configuration and an open configuration, and wherein the kickstand member, in the open configuration, is configured to prop up and/or retain the mobile electronic device in a non-horizontal position; and a grip detachably coupled to an accessory-facing surface of the kickstand member, wherein the grip is movable between an expanded configuration and a collapsed configuration. 17. The combination grip and kickstand accessory of claim 16 , wherein the kickstand member further comprises a base-facing surface opposite the accessory-facing surface, and wherein the base-facing surface of the kickstand member contacts the base member when the kickstand member is in the closed configuration. 18. The combination grip and kickstand accessory of claim 16 , wherein the grip in the expanded configuration is configured to be grasped by a user to securely hold the mobile electronic device when the kickstand member is in the closed configuration. 19. The combination grip and kickstand accessory of claim 16 , wherein at least a portion of the grip expands away from the accessory-facing surface of the kickstand member when moving from the collapsed configuration to the expanded configuration, and contracts towards the accessory-facing surface of the kickstand member when moving from the expanded configuration to the collapsed configuration. 20. The combination grip and kickstand accessory of claim 16 , wherein the grip comprises a top side, a bottom side, and a coupling portion, and wherein the top side of the grip expands away from the accessory-facing surface of the kickstand member when moving from the collapsed configuration to the expanded configuration, and contracts towards the accessory-facing surface of the pivotable member when moving from the expanded configuration to the collapsed configuration. 21. The combination grip and kickstand accessory of cl
