Thanks for this very informative statement.

Two questions spring to mind, one MP3-technical and one patent-technical:

1. which patent was the one worth issuing an opinion on?

2. why was the opinion not to be divulged publically?

Clearly, the specific patent is a matter of interest for those
developing in this area so they can effectively get advice.

The other question is "what kind of useful advice cannot be propagated,
and why?"...

cheers, Rich.
