Judge Richard Posner, of the US District Court in the Northern District of Illinois, has asked Apple to stop submitting "frivolous filings" in a patent fight with Motorola. "I've had my fill of frivolous filings by Apple," an order by the judge reads. The trigger for the reprimand was an Apple motion to block Motorola from deposing a particular expert. While the expert's identity is still under seal, Posner complained that one half of the motion was "frivolous," and a second "untimely."
