The US court rules that the Android devices running Java applications do not infringe on Gemalto’s patents.
The US Court of Appeals for the Federal Circuit has dismissed the patent infringement lawsuit filed by the French digital security company Gemalto against Android device manufacturers.
The court ruling comes almost four years after the French company filed a suit against Google, Motorola, Samsung and HTC, alleging that these firms infringed on its patented technology, which allows devices to run Java apps despite less powerful processors.
However, the top Android phone makers argued that in order to run Java apps, they depend on off-chip memory.
Although Gemalto did not contest the district court's verdict on direct infringement, it claimed that the devices indirectly infringed on its patents as they run Java apps in the same manner as mentioned in its patents, which were developed in the 1990s at the firm's research and development facilities in Texas.
In its ruling, the Court of Appeals stated that the French firm's argument was general, and concurred with the district court that the accused firms did not infringe on the patents.
In a statement, Gemalto CEO Olivier Piou, noted: "Gemalto's has consistently patented and broadly licensed its innovation so we are certainly disappointed by this judgment with regards to the scope of use of some of our intellectual property."
