RAH Color Technologies LLC is a privately held, single-owner licensing entity based in Alexandria, Virginia (originally Rochester, New York), formed in 2005 by Dr. Richard A. Holub, a color scientist and named inventor on essentially the entire portfolio. It has no parent, no public ticker, and no disclosed revenue or headcount; its own complaints describe a prior venture, Imagicolor Corporation (1998), that failed to commercialize, after which RAH was created as "a vehicle for an on-going licensing program." It is best characterized as a non-practicing entity / patent-holding licensor rather than an operating company — it does not make, sell, or service products.
Patent portfolio and technology. RAH holds roughly 27–35 issued U.S. patents (plus foreign counterparts) in digital color management. The families, with priority dates back to February 26, 1996, cover: (1) networked "system for distributing and controlling color reproduction at multiple sites" (e.g., U.S. 6,995,870; 7,729,008; 7,710,560; 8,416,444), (2) "methods and apparatus for calibrating a color display" (e.g., U.S. 7,104,648; 8,279,236), (3) color-printer calibration (U.S. 7,280,251), and (4) color calibration of color image rendering devices (U.S. 9,894,340; 10,560,676). Asserted technology centers on ICC-profile processing, gamut mapping, and remote/soft proofing.
Litigation posture. The case data show 50 suits as plaintiff against 7 defendant-side appearances — the classic NPE signature. Nearly every tracked matter is RAH asserting its portfolio; the seven "defendant" entries are Adobe IPRs (IPR2019-00627/-00628/-00629) and an EFI declaratory-judgment action, not affirmative counter-suits. RAH historically filed in plaintiff-friendly or home venues (N.D. Illinois, W.D.N.Y., and E.D. Texas Sherman Division for its 2020 Microsoft complaints), with many cases consolidated for pretrial into MDL No. 2874 in the Northern District of California.
Notable matters. Prominent defendants include Microsoft, Adobe, Xerox, Eastman Kodak, Heidelberger Druckmaschinen, Dalim Software, Quad/Graphics, Samsung, Fujifilm, Ricoh, Agfa, X-Rite, and Seiko Epson. RAH states it has licensed the portfolio to several large color-imaging manufacturers plus multiple end users; outside counsel has included Global IP Law Group and Merzbach Law Office. Outcomes and validity findings for specific patents are not summarized here.
