Abstract
Abstract A hand-held electronic telecommunications device is provided with a grip and protective casing made of elastomeric material for covering the back face and side walls of the device. The casing is provided with finger recesses on its exterior surface to permit the operator to reliably hold and even operate the device with one hand. The casing is constructed so as to be readily applied and even removed, as desired, by the operator himself. The manner by which the casing is supported on the device enables the casing material to avoid having to cover over any area of the front, operational face of the device, where such features as the ear piece, mouthpiece and push buttons are located.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
112 words
For use on a hand-held electronic telecommunications device defined by a housing having a front operational face with sensorial features with which the user interfaces, an opposed back face, and transversely extending side walls between said front and back faces, a grip and protective casing having a base and a continuous wall surface surrounding said base and upstanding inwardly from said base and having a securement member projecting inwardly from said wall surface for frictionally engaging at least one housing side wall of said telecommunications device, such that when applied to said telecommunications device housing said casing overlies said back face and all side walls but avoids contact with said front face.
Claim 2
Dependent Claim
112 words
For use on a hand-held electronic telecommunications device defined by a housing having a front operational face with sensorial features with which the user interfaces, an opposed back face, and transversely extending side walls between said front and back faces, a grip and protective casing having a base and a continuous wall surface surrounding said base and upstanding inwardly from said base and having a securement member projecting inwardly from said wall surface for frictionally engaging at least one housing side wall of said telecommunications device, such that when applied to said telecommunications device housing said casing overlies said back face and all side walls but avoids contact with said front face.
Claim 3
Dependent Claim
16 words

Claim 5
Dependent Claim
42 words
The grip and protective casing of claim 1, wherein said securement member comprises a flap extending further upwardly from said wall surface and hingedly connected to said wall surface, said flap having a locking element for attaching to said telecommunications device housing.
Claim 6
Dependent Claim
15 words
The grip and protective casing of claim 4, wherein said locking element comprises resilient prongs.
Claim 7
Dependent Claim
23 words
The grip and protective casing of claim 4, wherein said locking element is adapted to be releasably attached to said telecommunications device housing.
Claim 8
Dependent Claim
21 words

Claim 9
Dependent Claim
41 words
The grip anti protective casing of claim 1 or 7, wherein the interior surface of said base is formed with inwardly upstanding ribs for supporting said base above said back face when said casing is applied to said telecommunications device housing.
Claim 10
Dependent Claim
111 words
A combined hand-held electronic telecommunications device and grip therefor, comprising: telecommunications device housing having a front operational face with sensorial features with which the operator interfaces, an opposed back face, and transversely extending side walls between said front and back faces; casing having a base, a continuous wall surface surrounding said base and upstanding from said base and an open top into which said back face is received; and a securement member projecting inwardly from said casing wall surface for frictionally engaging at least one side wall or said telecommunications device housing, such that said casing overlies said back face and all side walls but avoids contact with said front face.
Claim 11
Dependent Claim
111 words
A combined hand-held electronic telecommunications device and grip therefor, comprising: telecommunications device housing having a front operational face with sensorial features with which the operator interfaces, an opposed back face, and transversely extending side walls between said front and back faces; casing having a base, a continuous wall surface surrounding said base and upstanding from said base and an open top into which said back face is received; and a securement member projecting inwardly from said casing wall surface for frictionally engaging at least one side wall or said telecommunications device housing, such that said casing overlies said back face and all side walls but avoids contact with said front face.
Claim 12
Dependent Claim
42 words
The combination of claim 9, wherein said telecommunications device housing is formed with a transversely extending recess, said securement member is a protuberance fit into said recess, and a plurality of such protuberances are spaced along said wall surface of said casing.
Claim 13
Dependent Claim
43 words
The combination of claim 9, wherein said securement member comprises a flap extending further upwardly from said wall surface and hingedly connected to said wall surface, said flap having a locking element for attaching itself to one said telecommunications device housing side wall.
Claim 14
Dependent Claim
29 words
