It looks like U.S. International Trade Commission judge Carl Charneski has managed to cause quite a stir in the GPS industry this month, with him first ruling earlier this month that chipmaker SiRF infringed on six of Broadcom's GPS patents, and him now recommending that the ITC issue an all out product import ban on products using the offending chips. Given that one of the supposedly infringing chips is the ever-present SiRF Star III, that would obviously shake things up in a pretty big way. A final decision on a ban won't come until December, however, and SiRF looks to be exploring all of its options in the meantime, including asking the U.S. Patent Office for reexamination of the contested patents. As Reuters reports though, that hasn't stopped SiRF's shares from falling 24 percent to an all time low on Tuesday, and at least one GPS device manufacturer doesn't look to be waiting around to see how things shake out either, with DigiTimes now reporting that Mitac is set to stop using SiRF chips in its GPS devices in the fourth quarter of this year. Then again, that is DigiTimes, but we doubt that'll be much consolation for SiRF right about now.
