uCloudlink Announces Progress in Patent Dispute

HONG KONG, July 14, 2020 – UCLOUDLINK GROUP INC. (“uCloudlink” or the “Company”) (NASDAQ: UCL), the world’s first and leading mobile data traffic sharing marketplace, today announced positive developments in its patent dispute with Simo Holdings Inc. (“Simo”).

In 2018, SIMO sued uCloudlink for infringing its U.S. Patent 9,736,689 (the “’689 Patent”). The U.S. District Court for the Southern District of New York (‘SDNY”) found in favor of SIMO in August 2019. In December 2019, SDNY issued a new order which concluded that uCloudlink’s redesigned devices were no longer infringing and lifted the injunction as to such redesigned devices. Additionally, uCloudlink appealed SDNY’s ruling and requested Ex Parte Reexamination (“EPR”) of the ’689 Patent by the U.S. Patent and Trademark Office (“USPTO”). The USPTO granted the EPR request and, on June 12, 2020, issued an Ex Parte Non Final Action rejecting all claims of the ’689 Patent.

Further, in response to SIMO’s claims of infringement of ‘689 Patent and trade secret misappropriation which were raised in the U.S. District Court for the Eastern District of Texas, uCloudlink filed a motion on July 8, 2020, moving to dismiss these claims, and alternatively to transfer (i) the infringement claim to SDNY and (ii) the trade secret claim to the U.S. District Court for the Northern District of California, which had dismissed this claim with prejudice.
