Congrats!
How is the case of fighting off Dolby's patent racketeering going? They tried to attack Snapchat for using AV1.
This will always happen. There are just some entities that can't stand not seeking rent.
Dolby's patents are garbage, and they know it. They managed to patent entropy coding somehow. This will not stand to challenges, and they managed to poke a well-resourced company.
Last update seems to be "lawsuit was filed" with zero updates since then. That stuff tends to move slowly.
