Mayer Brown secures $112 million jury victory for Maxell in patent infringement case against Samsung

WASHINGTON DC – Mayer Brown secured a significant trial victory for Maxell Ltd. in the US District Court for the Eastern District of Texas, obtaining a $111.7 million jury verdict against Samsung Electronics Co. Ltd. for willful infringement of three Maxell patents covering key smart device technologies.

The jury found that Samsung infringed all three patents, which relate to innovative methods for unlocking devices, locating recordings, and managing digital data, and awarded Maxell damages based on a running royalty through trial. The jury further determined that Samsung failed to prove the invalidity of two of the asserted patents and found the infringement to be willful.

This case is part of a broader global dispute between Maxell and Samsung regarding the unauthorized use of Maxell’s patented technologies in a wide range of personal electronic devices. Since July 2021, Maxell has engaged in discussions with Samsung regarding the alleged infringement, providing detailed information about the patents and the technology at issue. Despite these efforts, Samsung declined to enter into a licensing agreement, prompting Maxell to pursue legal action in multiple jurisdictions, including the United States, Germany, and Japan, as well as before the US International Trade Commission.  

The Mayer Brown IP team was led by partner Jamie Beaber in the firm’s Washington DC office and included partners Alan Grimaldi, Kfir Levy, James Fussell, Saqib Siddiqui, Bryan Nese, Michael Lindinger, Robert Pluta, and Amanda Streff Bonner, counsel Tiffany Miller and Alison Gelsleichter, and associates Tariq Javed, Seth Bruneel, Courtney Krawice, Séké Godo, and So Ra Ko in the firm’s Washington DC and Chicago offices.
