Patently Apple reported over the weekend that Apple's trademark application for the "iPad mini" term was refused by the U.S. Patent and Trademark Office, but The Verge Nilay Patel noted that the refusal was just a first office action.
The examiner’s major objection to the application is that the term is descriptive and doesn't create a unique trade mark that should be protected. The examiner said that all parts of the term ( namely, "i", "Pad", and "mini" elements) are not unique to this product.
