No, no news is no news.
If someone has a patent, then that might be nice for them, but is of
little interest to me.

If anyone takes patent action against any one about any code in the
kernel (or elsewhere in widely used FLOSS code) then that is a concern
to lots of people and (providing it becomes know) I suspect that a
lot of people will take interest.

However unless and until that happens, my personal attitude to other
people's patents is that they aren't my problem.  BUGs are my problem
not patents.
