1 case as defendant.
Epson Portland, Inc. (EPI) is the U.S. manufacturing subsidiary of Japan's Seiko Epson Corporation (SEC). It is headquartered at 3950 NW Aloclek Place, Hillsboro, Oregon, and was incorporated in 1985 (EPI job postings and environmental filings say "founded 1986," when production began). It is a wholly owned subsidiary of SEC, which is publicly traded on the Tokyo Stock Exchange (ticker 6724) with roughly 74,600 employees and consolidated revenue of about ¥1.41 trillion in the fiscal year ended March 2026. EPI does not publish standalone financials; third-party estimates of its own headcount and revenue vary widely (roughly 130–350 employees, tens of millions in revenue), so those figures are not reliable.
Operations. EPI manufactures Genuine Epson ink cartridges for inkjet printers, including ink production, precision plastic injection molding, assembly, and packaging, using Epson robotics. It also performs refurbishment of optical engines for LCD projectors and provides specialized engineering services to the Seiko Epson Group. From 1986 until 2001 it assembled printers (over 15 million units); a related Longview, Washington site produces synthetic quartz crystals for Epson's micro-device operations. It is classified under NAICS 325910 and holds ISO 9001/14001 certifications.
Litigation posture. EPI is an operating company, not a patent assertion entity. In the tracked data it appears only as a defendant — 0 plaintiff cases, 4 defendant cases — all captioned RAH Color Technologies LLC v. Seiko Epson Corp. et al. and filed December 20–21, 2010 in the U.S. District Court for the Western District of New York (Rochester). EPI was named alongside its parent and U.S. affiliates.
Context. RAH Color Technologies LLC is a Virginia limited liability company managed by inventor Dr. Richard A. Holub, formed in 2005 as a licensing vehicle for a color-management patent portfolio covering gamut mapping, ICC color profiles, and display/printer calibration; it asserted the same patents against Adobe, Xerox, Heidelberg, EFI, and others. The W.D.N.Y. venue reflects RAH's Rochester, New York ties rather than a plaintiff-friendly Texas district. Separately (outside the tracked data), EPI acted as an Epson co-plaintiff in 2006 ITC and Oregon district court actions against aftermarket ink-cartridge makers.
RAH Color Technologies LLC asserted the '546 patent against Seiko Epson Corp. and affiliated Epson entities. Defendants filed answers/counterclaims in 2011, and the case closed without a reported merits judgment.
