Commitment to Enforce Intellectual Property Rights.

Menlo Park, California – August 20, 2019 – Dali Wireless, a world-wide pioneer in digital radio distribution systems and digital predistortion technology, today announced that it will appeal a recent decision by the Patent Trial and Appeal Board (PTAB) invalidating several claims of U.S. Patent No. 9,531,473. “It is important to remember that a federal district court jury upheld the validity of the ’473 patent and found in favor of Dali; awarding Dali $9 million in damages for CommScope’s infringement of two patents,” noted Dr. Albert Lee, CEO of Dali. “Even if our appeal is rejected, almost 75% of the $9 million award ($6.6 million) was for CommScope’s infringement of a different patent and would be unaffected by any ruling on the ’473 patent.”

Relatedly, Dali has filed a second lawsuit against CommScope in the U.S. District Court for the District of Delaware. In the Delaware lawsuit (1:19-cv-00952-MN), Dali alleges infringement of U.S. Patent Nos. 10,080,178, 10,045,314, 9,847,816, and 8,682,338, which represent four distinct patent families that cover next-generation technology in wireless distribution systems. Dali is seeking damages and an injunction to stop the manufacture, sale, and distribution of CommScope’s OneCell and ION-E/Era C-RAN products.

Dr. Lee stated, “while the recent PTAB ruling is disappointing, Dali’s patent portfolio is broad and deep, and we are confident that we will prevail in our efforts to enforce it. Dali has invested tens of millions of dollars in its seminal technology and is committed to aggressively protect our intellectual property around the globe.”
