Cisco Systems is suing Apple for trademark infringement in a US federal court, for using the iPhone name.
Apple launched its new handheld mobile phone device under the iPhone name on Tuesday, at the hotly anticipated Macworld event in San Francisco.
Following the launch Cisco said it hoped to resolve the matter by Tuesday evening after negotiations.
Apple responded by saying the lawsuit was "silly" and that Cisco’s trademark registration was "tenuous at best".
