A federal appeals court handed Google a setback in a patent fight on Wednesday, tossing out part of a summary judgment in Google's favor in a lawsuit filed by Hyperphrase Technologies. Hyperphrase had filed suit in Wisconsin claiming that Google infringed on four patents used to make AutoLink and AdSense. The district court in Wisconsin tossed out the case, granting summary judgment in Google's favor. But the U.S. Court of Appeals for the Federal Circuit said it partially upheld the summary judgment, partially vacated it and remanded the case.
