Various studies are based on successful teleportation of maximally entangled coherent states. In many cases it has been found that teleportation is not very successful with non-maximally entangled states giving very less fidelity. In the present paper, we propose a scheme to teleport a tripartite entangled coherent state using a non-maximally entangled 4-partite state as a quantum channel. Our scheme involves Bell State measurements and the use of beam splitters and phase shifters. We have separated the vacuum state from even states and find that, even by taking a non-maximally entangled quantum state, we can get an almost perfect teleportation for an appreciable mean number of photons. The average fidelity of teleportation is found to be almost equal to unity when the mean number of photons is 2.
