The European Patent Office Board of Appeals has ruled in favor of Alcatel in its patent dispute with Bosch. The patent relates to multimode GSM and CDMA handset terminals, amongst other things. The invention is particularly suited to 3G and 2.5G handsets as it is back compatible with GSM networks.
European patent EP 297616 was filed in 1988. Since 1993, Bosch has wanted the complete revocation and annulation of the patent, claiming that the invention was obvious when it was patented.
The appeal to have the patent revoked has been thrown out and the patent remains. As a result, Bosch cannot appeal again.
