Motorola has been going toe and toe with RIM over alleged patent infringement both here in the US and across the pond in the UK. Motorola’s UK case focused on BIS and BES technologies, claiming that the two messaging systems infringe upon patents that Motorola holds for an RF-based message communication system. In ruling against Motorola, the judge noted that messages from BES servers were not suitable for RF transmission and that RIM’s BIS servers are physically located in Canada and are out of the court’s jurisdiction. In a further blow to Motorola, the court held that there was no inventive step and the patent itself was declared invalid. Sorry Motorola, better luck next time, we guess.
