New Mexico plaintiff Muvox LLC has expanded its sole litigation campaign—launched in August 2024 with cases against Bertelsmann SE & Co. (BMG Rights Management) and IBM—with a Western District of Texas suit against Meta Platforms (7:25-cv-00079). The plaintiff asserts a single patent generally related to determining a song’s “mood” based on “frequency characteristics” and selecting a different song with a similar “mood”. Meta Platforms is accused of infringement through the provision of the content recommendation system (which allegedly employs AI tools to analyze audio data and recommend content to users) within its Instagram platform.
