Well, it seems that Apple, Inc. and Cisco Systems, Inc. have come to their senses. I must confess, however, that the news that the two San Francisco Bay Area technology heavyweights have agreed to jointly use the name 'iPhone' is hardly unexpected. I have been expecting some such agreement since Apple's intial announcement of the iPhone at the MacWorld 2007 conference in January.
While I am not a lawyer, it would seem to me that the fact that the two companies are marketing entirely different markets and that neither is infringing on the other's core business would make it difficult for Cisco to win, though Apple's case is just as shaky, considering that Cisco does have a prior claim.
In either case, now both companies can focus on their respective product lines without engaging in a lengthy and expensive lawsuit which would ultimately serve only to line the pockets of the lawyers.
