Japanese court overturns Red RAW video patent

The Japanese Patent Office has declared one of Red’s key Raw video patents as invalid, following a challenge by Panasonic.

The court determined that many of the claims made in the patent, first filed in the US in 2008, would have been obvious to someone skilled in the subject area and familiar with existing developments.

The news, first reported by Thom Hogan , put Nikon’s video subsidiary in the position of trying to defend a patent that Nikon had previously argued was invalid .

The patent itself describes a high-resolution video camera that compresses its Raw data, and appears to correspond to the patent at the center of historic claims against Sony and Apple and the almost inevitable counter-suits from those companies. We reported on many of these challenges, as well as Nikon’s, over the years.
