"It is our belief that Apple intends to agree to the final document." Not so much. We're not quite sure what broke down in talks between Cisco and Apple, but they ain't playing friendly no more. Cisco just announced that it has filed a lawsuit in Northern California to prevent Apple from infringing upon its registered iPhone trademark. The word yesterday was that Apple and Cisco had been involved in "extensive discussions," and that they were expecting Apple to sign up for whatever final agreement they proposed. "Cisco entered into negotiations with Apple in good faith after Apple repeatedly asked permission to use Cisco's iPhone name," says Mark Chandler of Cisco. "There is no doubt that Apple's new phone is very exciting, but they should not be using our trademark without our permission." Obviously all we've heard so far is Cisco spin on the situation, but so far it sounds like they're being fairly reasonable with Apple on this -- it is their own dang trademark after all. So what gives, Apple?
