It’s no secret that RED is very protective of its patents, particularly the one covering the internal recording of compressed raw video. They’ve pursued it pretty relentlessly over the years, stifling the competition and probably setting back camera development by quite a few years. DJI and Kinefinity are rumoured to have removed their internal raw capabilities over RED’s threats. More recently, however, RED’s sights have been aimed towards Nikon.
Nikon announced in April that the Nikon Z9 was going to gain internal 12-Bit ProRes RAW and 8K 12-Bit N-RAW in a firmware update. The very next month, RED sued them over patent infringement claims as a result. In September, Nikon denied that they’d done so and now we know why. They’re claiming RED should’ve never been granted the patent in the first place and this video from FrameVoyager summarises the whole saga in probably the best way I’ve seen so far.
