A 20‑Year Gatekeeper Topples
The RED compressed RAW patent refers to a family of camera patents that covered visually lossless compression of RAW sensor data inside a video camera and, for almost two decades, largely dictated which manufacturers could offer internal RAW video recording and under what conditions. That gatekeeper has now fallen in one of the world’s key imaging markets, and the timing matters.
Panasonic launched an invalidation trial against RED’s Japanese “Video camera” patent (JP 5231529), arguing that its core claims were obvious combinations of existing technologies. The Japan Patent Office agreed, finding the invention lacked an inventive step. Nikon, which inherited the patent after buying RED, appealed—but on June 30 the Intellectual Property High Court dismissed that appeal and upheld the invalidation, confirming that this cornerstone of RED’s compressed RAW technology is legally treated as if it never existed in that jurisdiction. For camera makers, that is not a legal footnote; it is a strategic earthquake.
How One Patent Shaped RAW Video Recording Cameras
To understand why this camera patent invalidation matters, you have to appreciate how much power it held. RED’s “Video camera” patent family, which described transforming red and blue image data based on green pixel values before compression so Bayer RAW could be heavily compressed yet remain visually lossless, became the legal foundation for REDCODE and the model for compressed RAW technology in general.
For almost two decades, this intellectual property decided who was allowed to record compressed RAW internally and who had to fall back on workarounds such as partial demosaicing, external recorders, or alternative codecs. RED enforced it aggressively: it sued Sony over the F65, F55, and F5, forced smaller makers to strip CinemaDNG from their cameras, and became a central factor in Nikon’s decision to acquire RED after previous legal clashes over the Z9’s N-RAW. In practice, the patent helped keep internal RAW in the realm of higher‑end, carefully controlled products instead of a standard checkbox feature.
Why the Court Struck the Patent Down Now
Panasonic’s challenge succeeded where others failed because it persuaded both the patent office and the court that RED’s claims were not as groundbreaking as the industry had treated them. The Japan Patent Office ruled that the contested claims combined existing technologies and lacked an inventive step, while the Intellectual Property High Court agreed that many claims would have been obvious to a skilled person given prior developments at the time.
There is a certain irony here. Before buying RED, Nikon had argued against the validity of these same compressed RAW claims when it was accused of infringing them with N‑RAW on the Z9. After the acquisition, Nikon switched sides and tried to defend the patent, only to lose the appeal it inherited. The decision also arrives late in the game: the Japanese patent would have expired in April 2028 anyway, so the court has not only punctured RED’s aura of legal invincibility—it has shortened an already limited remaining commercial window.
What This Means for Your Next Camera
On paper, the immediate impact is narrow: the ruling removes one of the longer‑standing patent barriers in Japan and adds a formal finding of invalidity to the public record. In practice, that matters more than it sounds. When a court says that a once‑dominant patent lacked inventive step, it undercuts the narrative that compressed RAW recording inside a camera is inherently proprietary magic.
Many major brands already offer internal RAW video options in some form, and Panasonic records compressed RAW internally on models like the GH7, S1RII, and S1II using ProRes RAW, under undisclosed arrangements that were shaped by RED’s portfolio. With this legal roadblock removed in one major market and the expiration date approaching anyway, manufacturers gain more confidence to treat internal RAW as an ordinary feature rather than a legal minefield. That does not guarantee cheaper cameras, but it does tilt the competitive pressure toward offering better codecs and fewer artificial product tiers.
A Local Ruling with Global Signal Value
There are important caveats. The invalidation applies only to the Japanese patent; related patents in other jurisdictions still stand, and existing licensing agreements do not vanish overnight. Exactly what this means commercially is hard to pin down, and Nikon could still try to take the fight to a higher court, though that is an open question. One potential area of fallout is how licensing arrangements around compressed RAW formats such as ProRes RAW evolve, but the details of those agreements remain private.
Still, the signal is clear: compressed RAW technology is no longer protected by an unquestioned fortress in at least one key market. The decision chips away at the idea that RAW video recording cameras must live under a single company’s legal shadow. As more parts of the patent family expire or face similar scrutiny, we should expect RAW video to look less like a premium luxury and more like a baseline expectation—especially in higher‑end mirrorless and cinema systems. Whether Nikon pushes further appeals or quietly pivots, the age of RED’s legal chokehold on internal RAW is ending.
