A federal judge has ruled in favor of Sony Corp in a long-running case, overturning a jury verdict for L-3 Communications Corp [LLLCO.UL] and invalidating several parts of an image sensor patent held by the defense contractor. District Court in Delaware said on Friday that the jury in 2013 was wrong to find L-3s patent claims were not obvious, a key criteria to ensure an invention is sufficiently unique to be patented. New York-based L-3, which supplies a wide range of military and civil electronics equipment and services, sued Sony in 2010 over a patent for the image sensors, which it said were originally developed for military low-light applications. L-3 said Sony infringed the patent by using the technology in its digital still and video cameras, computers and mobile phones.
