Debates have swirled over Cisco's right to the trademark after the company acquired the rights several years ago, its consumer wireless division last Spring began shipping an VoIP-based iPhone product line that uses the internet to make phone calls; however, Apple claims that the phones differ significantly because its iPhone works as a cellular phone with music capabilities. Apple has exclusively partnered with Cingular, now AT&T, in the US and reports claim that Rogers Wireless will carry the iPhone in Canada; however, Apple may face a similar trademark claim in Canada and has not announced the product for that market. After a public war of words in which Apple called the lawsuit 'silly', Cisco CEO John Chambers described the trademark lawsuit as a minor skirmish; on Thursday, both companies reiterated previous statements that they want to use the extra time to reach a settlement, according to the report. Despite reports that royalties for the iPhone name could reach into the hundreds of millions, Cisco has said that the lawsuit is not about royalties and simply wants Apple to commit to interoperability with its own devices, but has not provided any details.
