SHENZHEN, China, Dec. 3, 2024 /PRNewswire/ -- On November 26, 2024, Access Advance LLC ("AA") and TCL Electronics Holdings Limited ("TCL" or "Client") announced that TCL had officially joined the HEVC Advance Patent Pool as a licensee. PurpleVine IP Group ("PurpleVine") played a pivotal role in this achievement, providing full-spectrum services, including strategic planning, global litigation management, and licensing negotiation support. PurpleVine's efforts were instrumental in helping TCL finalize agreements with AA and multiple HEVC Advance licensors, resolving years of complex global litigation over HEVC standard-essential patents("SEPs").

Since 2021, leading HEVC Advance licensors - including Dolby, GEVC, Philips, Mitsubishi Electric, JVCKENWOOD, NEC, ETRI, and IP Bridge - have filed dozens of infringement lawsuits and sought injunctions against TCL across jurisdictions such as Germany, the Unified Patent Court (UPC) in Europe, and Brazil. PurpleVine provided TCL with a comprehensive defense strategy tailored to each jurisdiction. Working closely with local counsel, the PurpleVine team devised FRAND-compliant arguments, non-infringement defenses, and patent invalidation strategies that not only neutralized injunction threats but also achieved an outstanding success rate of over 90% in invalidating asserted patents during first-instance rulings.

PurpleVine also spearheaded counteractions against AA and HEVC Advance licensors in multiple jurisdictions, including China, Brazil, and Germany. Notably, PurpleVine assisted TCL in filing two landmark cases in Chinese courts - one challenging SEP licensing rates and another alleging abuse of market dominance. These cases were the first in the world where courts asserted jurisdiction over SEP pool licensing rates and alleged monopolistic practices, setting a groundbreaking legal precedent.

Daniel Fu, General Counsel of TCL, stated, "We are pleased to have signed a license with Access Advance's HEVC patent pool, with the help of PurpleVine IP. The transaction is beneficial to the licensing ecosystem and the development of cutting-edge technologies for the welfare of consumers."

This multi-jurisdictional case, involving complex legal challenges, spanning several years, highlights PurpleVine's expertise in managing high-stakes IP disputes. PurpleVine's strategic leadership, effective litigation management, and skilled negotiations reaffirm its position as a leading provider of cross-border intellectual property services.
