Google's application for the Nexus One trademark has been denied by the US Patent and Trademark Office (USPTO), which says it could be confused with a trademark on the word Nexus that's registered to wireless telecoms firm Integra Telecom.
The denial is not final and Google now has the opportunity to submit evidence and arguments in support of approval.
Similarity of the words, goods and/or services and trade channels were the most relevant factors the USPTO used in issuing the denial, it said.
In a statement, Integra said it appreciates that the USPTO is protecting its trademark rights. It also said it hopes to work the matter out with Google. "Google hasn't contacted us since the PTO issued its objection but we hope we can work together to achieve our respective business goals," said John Nee, Integra's vice president of corporate communications.
Google did not reply to a request for comment.
The Nexus One runs Google Android, and Google sells it exclusively from its website in the US. The Nexus One's UK release is scheduled for April.
