Panasonic has achieved something that some of the biggest names in imaging and technology have previously struggled to do: successfully challenge one of Red Digital Cinema’s hugely influential compressed RAW video patents.
A Japanese court has upheld the invalidation of key claims within Red’s Japanese “Video Camera” patent, finding that significant parts of the claimed invention lacked the necessary inventive step because they would have been obvious to someone skilled in the field and familiar with existing technology.
The ruling follows an earlier challenge brought by Panasonic and represents a significant moment for a patent family that has influenced the development of digital cinema cameras for almost two decades.
The case relates to Japanese Patent No. 5231529, which traces back to Red’s compressed RAW video technology and describes a high-resolution video camera capable of recording compressed RAW image data internally.
Panasonic challenged the patent through an invalidation proceeding, with the Japan Patent Office ruling in October 2024 that a number of its claims were invalid.
Nikon, having acquired Red Digital Cinema in 2024 and inherited its intellectual property, subsequently became involved in defending the patent, but Japan’s Intellectual Property High Court dismissed the challenge on June 30 2026 and upheld the invalidation.
That creates a particularly unusual situation for Nikon. Before acquiring Red, Nikon had itself been accused of infringing Red’s compressed RAW technology with its N-RAW video implementation and argued against the validity of Red’s patent claims during the dispute.
Nikon eventually solved that particular problem spectacularly by acquiring Red outright, bringing the cinema camera company, its technology and its intellectual property portfolio under the Nikon umbrella. It now finds itself attempting to defend technology that, only a few years earlier, it had been challenging.
The importance of Red’s compressed RAW patents goes far beyond Nikon. Similar intellectual property has played a major role in disputes involving companies including Sony and Apple, with the latter previously challenging Red patents relating to compressed RAW recording without success.
Red’s technology helped establish a powerful position around recording high-resolution compressed RAW video internally, something that became increasingly important as mirrorless and cinema cameras began offering ever more sophisticated video capabilities.
The landscape, however, looks very different today.
Canon, Panasonic, Sony, Nikon and Blackmagic Design are among the manufacturers now offering cameras capable of sophisticated internal RAW recording in one form or another, while Nikon has begun integrating Red technology more directly into its own video ecosystem following the acquisition.
Panasonic’s victory therefore arrives at an interesting moment, although it is important to stress that the judgment concerns the Japanese patent and does not automatically invalidate Red’s related patents or licensing arrangements elsewhere in the world.
Exactly what this means commercially remains much harder to determine. One potential consequence could involve licensing arrangements surrounding compressed RAW formats such as Apple ProRes RAW, although the details of Red’s licensing agreements have historically remained private and Nikon now owns the company and its patent portfolio.
What is clear is that Panasonic has managed to successfully overturn key claims in Japan where challenges from some considerably larger technology companies had previously failed elsewhere, and that alone makes this a fascinating development in the long-running story of compressed RAW video.
