Dolby’s announcement:
“Dolby recognizes the May 23, 2023 statement from the Alliance for Open Media, which acknowledges the freedom of innovators such as Dolby to negotiate mutually agreeable terms for a license to their valuable AV1 patent portfolios. As such, Dolby reiterates and affirms that it has never accepted, and does not intend to be bound by, the AOM Patent License 1.0.” – Dolby Professional
