It's time to let Microsoft or whoever supplies your DMT software that "We" (as in them too) are being sued.
When you bought the software to encode and facilitate this transfer of video, were you told about Acacia's license?
Perhaps if the vendors get a few thousand of these letters, they will feel more involved.
Dear Microsoft,
I am using Microsoft Streaming Media Server and it has been alledged by Acacia Research that the technology you have sold me is not yours to sell. As a party in this matter, we need to discuss our defense. Please call me regarding this matter.
