Defended Nalu Medical in a patent lawsuit filed by Nevro over spinal cord stimulators, which included injunctive relief to prevent Nalu from commercializing its recently FDA-approved neurostimulation system.

Represented Zodiac Pool Systems LLC and Zodiac Pool Care Europe, leading manufacturers and innovators in the pool care industry, in a patent infringement and importation investigation at the International Trade Commission, with a related action in the Central District of California, against Wybotics, Co. Ltd. (d/b/a Winny Pool Cleaner), Tianjin Pool & Spa, Aiper Inc., Aiper Intelligent, LLC, and Shenzhen Aiper Intelligent Co., Ltd. The investigation involved two Zodiac patents covering pioneering technology in robotic pool cleaners. We were able to stop these entities’ infringement before trial. Specifically, before the close of fact discovery, Zodiac settled favorably with the Aiper entities on confidential terms, leading to the issuance of a consent order which bars Aiper from importing or selling any of the Accused Products in the United States. Zodiac also obtained sworn representations during discovery from Wybotics that it had completely stopped manufacturing, importing, and selling the Accused Products in the United States. Certain Robotic Pool Cleaners and Components Thereof, U.S. ITC Inv. No. 337-TA-1326; Zodiac Pool Care Europe v. Wybotics, Co. Ltd. et al, No. 2:22-cv-05271 (C.D. Cal.).
