Back in August Motorola filed a new round of patent infringement claims against Apple with the US International Trade Commission, seeking an import ban on the iPhone and the iPad — but in a recent filing the company mysteriously withdrew the complaints. It's unclear just what led Google-owned Motorola to make the move; normally we'd expect this type of withdrawal if a settlement was near, but in the filing itself Motorola specifically states that "There are no agreements between Motorola and Apple, written or oral, express or implied, concerning the subject matter of this investigation."

Whether the move is indicative of concerns Motorola had with its case — or something else entirely — remains to be seen. We've reached out to Apple and Motorola for comment, and will update you with any further developments.
