MR Technologie GmbH is a privately held German company primarily focused on the assertion and licensing of intellectual property related to data storage solutions. While its corporate purpose, as registered in Hamburg, Germany, includes the manufacture, development, and sale of IT products, as well as research and development, its public profile is dominated by patent litigation. The company was formed by Dieter Suess, a professor at the University of Vienna, in 2020 specifically to license his patents and partner with companies to develop magnetic recording technologies. No information regarding its employee count or revenue range is publicly available.
The company's core intellectual property centers on advanced methods to enhance the signal-to-noise ratio and increase areal density in hard disk drive (HDD) recording media through multi-layer exchange spring recording technology. These patents aim to improve storage capacity and performance in hard disk drives.
MR Technologie GmbH operates as a Non-Practicing Entity (NPE), or patent assertion entity, actively asserting its patent portfolio against manufacturers in the data storage industry. This posture is evident from its consistent role as a plaintiff in patent infringement lawsuits, with zero defendant cases in our tracked database. The company has brought multiple suits in U.S. federal courts, including the U.S. District Court for the Central District of California and the U.S. District Court for the District of Minnesota.
Notable litigation includes MR Technologie GmbH v. Western Digital Technologies Inc. in the U.S. District Court for the Central District of California. In August 2024, a jury awarded MR Technologie $262 million in damages, plus $117 million in prejudgment interest, for a total of approximately $380 million, for Western Digital's infringement of U.S. Patent Nos. 9,928,864 and 11,138,997. MR Technologie subsequently filed another case against Western Digital (Case No. 8:24-cv-01848) in the same district, asserting a related patent, which was dismissed with prejudice in July 2025, likely indicating a confidential settlement. The company has also initiated patent infringement lawsuits against Toshiba and Seagate Technology.
