US court revives Apple patent lawsuit against Google

Seeking court-ordered sales ban.

A US appeals court has given Apple another chance to seek a sales ban against Google's smartphones by reviving dismissed patent claims the iDevice giant made against Motorola Mobility.

The appeals court also revived a patent claim Motorola Mobility had made against Apple but ruled Motorola could not seek a sales ban of its own.

Apple and companies that make phones using Google's Android software have filed dozens of such lawsuits against each other around the world to protect their technology.

Despite years of court challenges to Android, Apple has not been able to win an injunction.

The US Court of Appeals for the Federal Circuit had been hearing two cases - one in which Apple accused Motorola Mobility, which has since been bought by Google, of infringing its patents. Motorola, in turn, accused Apple of infringing three patents, including one that is essential to ensuring smartphones are interoperable.

The cases were consolidated at the US District Court for the Northern District of Illinois. Judge Richard Posner, who took the case, dismissed it in 2012 before trial, saying that neither company had sufficient evidence to prove its case.

Posner had ruled an injunction barring the sale of Motorola phones would harm consumers. He also had ruled that even if infringement occurred, Apple could not sue because it could not prove it had been hurt by the infringement.

But the appeals court decided Posner defined one of Apple's patents too narrowly and ordered him to reconsider Apple's request for an injunction.

The appeals court affirmed the lower court's decisions on two Motorola Mobility patents. But, as in the case of the Apple patent, it disagreed with the lower court's decision that Motorola Mobility would be entitled to no damages even if infringement was proven on a third patent.

The appeals court said, however, that Motorola Mobility cannot request an injunction for infringement of that patent.

Since the appeal began, Google announced that it was selling Motorola Mobility's handset business to Lenovo but would keep the vast majority of the patents. It is unclear if Lenovo will assume liability in the patent fights.

Apple and Google both declined to comment.
