A Landmark Camera Patent Ruling That Finally Loosens RAW Video
The RED RAW patent is a long‑running “video camera” patent family covering visually lossless compressed RAW video recording inside a camera, which for almost two decades set the terms for which manufacturers could offer internal RAW and at what cost, shaping codec design, licensing deals, and mirrorless RAW recording strategies across the industry. Panasonic has now cracked that fortress in Japan. The Japanese Patent Office invalidated one of RED’s key compressed RAW video patents after a challenge by Panasonic, concluding that many claims would have been obvious to a skilled practitioner familiar with existing developments. Nikon, which inherited the patent after buying RED, appealed—and lost—when the Intellectual Property High Court upheld the invalidation on June 30, 2026. Under Japanese law, that means the patent is treated as if it never existed, removing a major legal barrier to alternative compressed RAW implementations in that market.
How RED’s Compressed RAW Video Once Dictated the Rules
To understand the shockwaves from this camera patent ruling, you have to appreciate how dominant RED’s technology was. When the RED ONE arrived in 2007, its REDCODE RAW made compressed RAW acquisition practical compared with earlier uncompressed RAW systems that demanded huge storage and bandwidth. The Japanese patent at issue, number 5231529, titled “Video camera” and registered from application 2010‑503253, describes transforming red and blue Bayer data based on green pixel values before compression so the image remains visually lossless after demosaic. That idea, broadly claimed, forced companies into workarounds or licenses. Some stripped CinemaDNG from cameras once proprietary codecs like BRAW were in place, while external recorders licensed technology so ProRes RAW could exist without direct infringement. According to one report, this patent family had survived every serious legal attack for over fifteen years, from Sony to Apple, until Panasonic’s successful challenge.
Panasonic’s Win and Nikon’s Awkward Defeat
Panasonic’s move was both strategic and symbolic. It filed an invalidation trial against Japanese patent 5231529, arguing that the contested compressed RAW video claims combined known technologies and lacked an inventive step. The Japan Patent Office agreed, declaring them invalid, and Nikon—having acquired RED and its patent portfolio—stepped in to defend a patent it had once attacked in US court. On June 30, 2026, the Intellectual Property High Court dismissed Nikon’s appeal and upheld the invalidation, a defeat that underlines how fragile even powerful intellectual property can become once courts start questioning its originality. Nikon famously ended its previous dispute with RED by buying the company, then applied RED’s cinema camera and RAW know‑how to recent Nikon models. Losing a core patent in its home market to a domestic rival changes Nikon’s leverage: compressed RAW is no longer their exclusive bargaining chip, at least in this jurisdiction.
New Competitive Dynamics for Mirrorless RAW Recording
With the RED RAW patent treated as if it never existed in Japan, the competitive landscape shifts in subtle but important ways. For years, RED’s compressed RAW video claims determined who could offer internal RAW and under what licensing conditions. Now third‑party manufacturers see a clearer path to developing their own compressed RAW solutions for Japanese‑market cameras without worrying about this particular patent family. Canon, Panasonic, Sony and Blackmagic already ship bodies with internal RAW video capture, often through codecs engineered to sidestep RED’s claims. Panasonic itself records compressed RAW internally: the LUMIX GH7 introduced internal ProRes RAW in 2024, followed by models like the S1RII and S1II, presumably under prior arrangements tied to the now‑invalid patent. Whether this ruling encourages broader mirrorless RAW recording, more aggressive codec innovation, or simply quiet firmware updates remains an open question—but the door is now less guarded.
What It Means for Filmmakers, Firmware, and the Next Two Years
For everyday filmmakers, this is not an instant revolution, but it removes one of the biggest legal brakes on internal compressed RAW video in Japan. One tangible possibility is the abolition of license fees reportedly owed to RED from users of Apple’s ProRes RAW codec, though there is no guarantee that any savings flow through to camera prices or recorder costs. The Japanese patent would have expired in April 2028 anyway, twenty years after its filing date, so the commercial window opened by this ruling is real but finite. In the near term, the impact is most likely to show up in firmware and codec roadmaps: more bodies adding internal RAW modes, fewer artificial feature gaps between territories, and more experimentation across different mount systems. The two big questions now are whether Nikon escalates to Japan’s Supreme Court and how freely internal RAW spreads in cameras sold into that market. If manufacturers seize the opportunity, filmmakers stand to gain more choice and less legal friction.
