The U.S. Patent Office did not accept Google's application for the "Nexus One" trademark.

Google filed an application for the Nexus One trademark back on 10th December 2009 for use in connection with mobile phones. However, the Trademark Office has recently issued a notice of refusal:

SECTION 2(d) REFUSAL ? LIKELIHOOD OF CONFUSION

Registration of the applied-for mark is refused because of a likelihood of confusion with the mark in U.S. Registration No. 3554195.

The refusal has been issued on the grounds that the mark could conflict with an existing NEXUS trademark (3554195) granted on December 30, 2008 to Integra Telecom under the same class with a description which includes the provision of telecommunication services and the transmission of voice and data.
