They're definitely pursuing patents...

> The authors of the paper have filed several patents relating to the subject matter contained in this paper in the name of Microsoft Corporation.

It's whether Microsoft will be fair and flexible licensing their patents to third-parties.

Otherwise I'd suggest that if they keep it all to themselves and charge like a wounded bull, uptake would be quite limited.

At least until the original patents expires, which might be the better strategic move for third-parties in light of a hostile Microsoft given how long this archival format is expected to last.
