Android phones do not infringe on Gemalto's patents, US court rules

Loek Essers | June 23, 2014
Android devices running Java applications do not infringe on patents belonging to SIM card maker Gemalto, the U.S. Court of Appeals for the Federal Circuit ruled.

However, this argument is too general, the Court of Appeals said, adding that the cache memory functionality that is the basis for Gemalto's theory was employed by microprocessor-based systems at the time of the invention.

"We agree with the district court that the accused devices do not infringe ... due to their use of cache memory," the Court of Appeals said Thursday, affirming the district court's judgement of no infringement.

Gemalto said it was disappointed by the judgment, but said the decision has no impact on its licensing business.
