Following a splashy keynote delivered by Apple CEO Steve Jobs to introduce a new smartphone, Cisco Systems has filed suit against the Mac-maker in a wrangle over the trademarked name “iPhone.”

Although Cisco had noted before Apple’s smartphone debut that it owned the “iPhone” trademark, the two companies had been in discussions about ways to share the brand. As a response to those negotiations, Cisco reportedly sent over an agreement on January 8.

Apple representatives did not sign it, and are now calling the lawsuit “silly,” citing the fact that several other companies have already been using the iPhone name for VoIP phones.

Apple spokesperson Natalie Kerris was quoted in news reports as saying that the company believes Cisco’s trademark registration is tenuous, and that Apple is prepared to be challenged.

Name Game

Cisco obtained the iPhone trademark in 2000 after acquiring InfoGear, the company that had been granted the trademark in 1996.

Even though the brand was in Cisco’s portfolio of trademarks, Apple’s potential move into cell phones had been talked about unofficially for several years as the iPhone, particularly by bloggers and analysts. Apple registered the domain name iPhone.org in December of 1999.

Apple executives have noted that it tried to obtain the trademark from Cisco in the past, but was ignored. Cisco claims that Apple created a front corporation to try and apply for the application, an allegation that Apple refuses to acknowledge.
