Currently the Vorbis patent issue covers these threads:
Vorbis development, status & patent issues PART 1 - NON-technical discussion
Vorbis development, status & patent issues PART 2 - Technical discussion (This thread)
/Moderator comment

By looking at this:
http://www.xiph.org/archives/vorbis-dev/20...2/index.html#83
it seems that Xiph (at least in 2000) was open to the idea of disclosing the patent research.
Is this position changed now, or does it still stand?

Let me try to "preach to the deaf" once again...

Before trying to decide "scientifically" if a codec infringes on a patent, one has to know "scientifically"
what the patent claim means. Unfortunately patent claims are not written by scientists, but they
are written by lawyers with intentional vagueness. The objective is to make it as broad as possible and, eventually, denfend it in court. Hence, any tentative to seriously analyze a patent situation should involve a lawyer to "extract" the precise meaning of the patent claim. Worse, a definitive answer needs a judge.

Otherwise, all of our arguments will have to start with a "According to my analysis of claims patent", as Ivan's post above. The same aspect of possible different interpretations was raised by sthayashi in another post.

Is it clear now why Xiph should avoid to answer this thread without consulting a lawyer?

Considering these arguments, is it technically sound to "ask scientifically if a patent is being infringed"? Hey, I just stated a meta-question smile.gif! I have the opinion that the answer of this question is no. However most people here seems to ignore this aspect and insist on having a pseudo-scientific discussion on a matter that is not solely in the science domain.
