Proprietary is independent of patents. Different systems. There already exists open licensed, but patent encumbered formats or their inverse. WAV is proprietary, but again, is fully documented and there exists open licensed encoders and decoders.
I have no idea why it still remains proprietary, but its an old format, and IBM/MS probably just don’t really care about it since it’s last update was over a decade ago.
What’s proprietary about a format older than 25 years, meaning all possible patents have elapsed?

What makes it proprietary if it is documented and free to use?
