Defendant
4 cases as defendant.
Heidelberger Druckmaschinen AG (trading as HEIDELBERG) is a German printing-press and print-technology manufacturer headquartered at Kurfürsten-Anlage 52–60, Heidelberg, Germany. Founded in 1850 by Andreas Hamm (some filings give an 1900 incorporation date for the current stock corporation), it is publicly listed on the Frankfurt Stock Exchange (ticker HDD) and reports no controlling parent. Its fiscal 2024/25 revenue was approximately €2.28 billion, down from €2.395 billion the prior year, with an adjusted EBITDA margin of about 7.1 percent and roughly 9,500 employees worldwide; it sells in more than 170 countries and operates production sites in several countries, including China and the United States.
Operations. HEIDELBERG develops and manufactures sheetfed offset printing presses (Speedmaster series), the Boardmaster inline flexographic press, and digital printing systems including the Versafire and Jetfire presses and the Gallus One/Five/Alpha and Labelfire label presses. It supplies Prinect production/workflow software, postpress and finishing equipment and robotics, consumables, and services, and also operates an EV charging-infrastructure subsidiary, Amperfied. The company reports in two segments, Print Solutions and Packaging Solutions (packaging now accounts for roughly half of order intake); it has discontinued earlier ventures in printed electronics and the Zaikio software platform. This is an operating manufacturer, not a patent-holding shell.
Litigation posture. All four tracked U.S. cases name HEIDELBERG as a defendant; it appears as plaintiff in none. That pattern is consistent with an operating company being targeted rather than an entity asserting patents. Every tracked suit was filed by RAH Color Technologies LLC, a Virginia limited liability company owned by inventor Dr. Richard A. Holub; a federal court record describes RAH as a non-practicing entity that licenses and enforces Holub's patents, which are directed to color management and color reproduction across networked devices.
Notable cases. The tracked matters are the 2018–2019 RAH Color Technologies LLC v. Heidelberger Druckmaschinen AG suits, originally filed in the U.S. District Court for the Northern District of Illinois and folded into MDL No. 2874, which was transferred to the Northern District of California. The same MDL consolidated RAH's parallel actions against Adobe and other printing/imaging companies. Court filings state HEIDELBERG has had notice of the asserted '008 patent allegations since at least November 2014, with the asserted claims focused on print workflow and color-reproduction systems.
RAH Color Technologies LLC filed suit against Heidelberger Druckmaschinen AG in the Northern District of Illinois. The action was transferred to the Northern District of California as a tag-along to MDL No. 2874 under case number 3:19-cv-00517, and the Illinois docket closed.
MDL No. 2874 consolidated RAH Color Technologies LLC's infringement actions against Adobe, Xerox, and others with Electronics For Imaging's declaratory-judgment action. The NPE Litigation Database lists the MDL as involving U.S. Patent 7,710,560; final judgment was entered on September 27, 2021, and the MDL docket closed July 26, 2022.
RAH Color Technologies LLC asserted U.S. Patent 7,729,008 against Heidelberger Druckmaschinen AG; the case was dismissed by agreement on 2019-07-23.
Asserted '870, '444, and '704; transferred into MDL No. 2874 by Conditional Transfer Order.
