Appeals court rules against Google in patent suit

Court sends patent suit back to lower court in case over Google's AutoLink toolbar feature.

An appeals court has reinstated a patent lawsuit filed against Google over a toolbar feature called AutoLink that provides links to online maps or books on Amazon.com, according to a Bloomberg News report.

Wisconsin-based HyperPhrase Technologies sued Google in 2006 for patent infringement. The case was thrown out a year ago by a district court judge, but this week the U.S. Court of Appeals for the federal circuit in Washington said the lower court judge had erred in interpreting some of the patents and sent the case back.

However, the appeals court agreed with the lower court ruling on a claim that Google's AdSense did not infringe on HyperPhrase's patents.
