This was posted on Sony's pro video website about the RED suit:
On February 12, 2013, Red Digital Cinema ("Red") sued Sony Corporation of America and Sony Electronics Inc. and alleged that the Sony PMW-F5, PMW-F55, and F65 digital cinema cameras infringe two Red patents. The F65 has been commercially available for over a year and the F5 and F55 were announced in October, 2012.
Sony has now had an opportunity to study Red's complaint and the asserted patents, and categorically denies Red's allegations. Sony intends to defend itself vigorously in the Red lawsuit. Sony looks forward to prevailing in court, thus vindicating the Sony engineers who developed Sony's quality digital cinema cameras.
