Cox Patent Portfolio Litigation

On April 4, 2014 and December 3, 2014, we initiated litigation against Google Inc. (“Google”) and YouTube, LLC (“YouTube”) in the U.S. District Court for the Southern District of New York for infringement of several of our patents within our Cox Patent Portfolio which relate to the identification of media content on the Internet. The lawsuit alleged that Google and YouTube had infringed and continued to infringe certain of our patents by making, using, selling and offering to sell unlicensed systems and related products and services, which included YouTube’s Content ID system.

The litigations against Google and YouTube were subject to court ordered stays which were in effect from July 2, 2015 until January 2, 2019 as a result of proceedings then pending at the Patent Trial and Appeal Board (PTAB) and appeals to the U.S. District Court of Appeals for the Federal Circuit. Pursuant to a joint stipulation and order, entered on January 2, 2019, the parties agreed, among other things, that the stays with respect to the litigations were lifted. In January 2019, the two litigations against Google and YouTube were consolidated. The consolidated actions proceeded and discovery was subsequently completed. On April 24, 2024, following a motion for summary judgment by the defendants, the U.S. District Court for the Southern District of New York issued a judgment dismissing our patent infringement claims finding that the asserted claims of two of the patents are invalid for indefiniteness and granting summary judgment that the asserted claims of another asserted patent are not infringed by Google’s accused system. The Court’s ruling disposes of all of our claims in the case. On May 14, 2024, we filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit and the appeal is pending.
