The US Patent and Trademark Office has denied Apple’s request to trademark the term “iPad mini,” according to a report. In a letter to Apple, the USPTO describes the term as “merely descriptive of a feature or characteristic of the goods,” therefore, the trademark registration was refused. The examiner’s description is a bit curious, as iPad is already an Apple trademark, but that term is also referred to as “descriptive” in the letter. There’s still a possibility Apple could be approved for the “iPad mini” trademark after further review, though the burden is now on Apple to counter the Office’s interpretations. Notably, Apple successfully trademarked many variations on the iPod name, including iPod shuffle, classic, and touch, but does not appear to have trademarked iPod mini. [via Forbes]
