Cisco sues Apple

Cisco Systems, with Chief Executive John Chambers, sued Apple Inc. in federal court on Wednesday, claiming that Cisco owns the iPhone trademark. Apple Chief Executive Steve Jobs unveiled the long awaited Apple iPhone at the MacWorld trade show in San Francisco on Tuesday, but Cisco claims that Apple does not have the right to use the name 'iPhone'.

In spite of some reports yesterday to the contrary, the matter of the high-profile product's naming had not been resolved behind the scenes between two of the biggest names in Silicon Valley.
