MNTech and Elo Touch Solutions resolve multi-patent, multi-venue dispute with 3M regarding touch screen technology

February 2019

Client(s) MNTech Co., Ltd.

Jones Day represented MNTech Co., Ltd. and Elo Touch Solutions, Inc. in a four-patent dispute with 3M regarding touch screen technology. In January 2018, 3M filed a complaint alleging infringement of four patents by Elo in the U.S. District Court for the District of Delaware. Later that year, on behalf of both Elo and MNTech, Jones Day prepared and filed petitions for inter partes review challenging all claims of all four patents-in-suit. The dispute was resolved in January 2019. The PTAB proceedings were terminated and the district court action was dismissed with prejudice.

MNTech Co., Ltd. and Elo Touch Solutions, Inc. v. 3M Innovative Properties Co., IPR Nos. 2019-00254, -00256, -00261, -00278 (PTAB); 3M Company, et al. v. Elo Touch Solutions, Inc., No. 1-18-cv-00011 (D. Del.)
