You see that as odd because you are reading it as "here are a list of
patents that W3C thinks apply to SVG".

In fact, it is "here is a list of claims that have been made". The Apple
claim was made a *long* time ago, more than a year ago; and the SVG
working group was aware of the claim. We don't believe that this patent
claim is a barrier to SVG adoption. But we can't make up developers
minds for them. We give them the information and they make up their own
minds.

I have asked Adobe to clarify their licensing terms since they contain a
condition that was future-looking when originally submitted but no
longer needs to be conditional now that all the working group members
have made their license terms known.

There was abundant input on the SVG specification from members of the
pubic, small companies, nonprofit organisations, and the open source
community.

If you are referring to input from those sorts of organisations on the
PPF, then you would need to ask someone else about that.
