Because of the necessity to maintain attorney client privilege, there
may not be any public evidence of Debian following the policy.

If someone knew (or thought) that we were distributing software that
violated a specific patent, they should e-mail [email protected] to
discuss the issue. They shouldn't file a bug, nor should they discuss it
on this mailing list. They may be wrong or right, but discussing it here
could expose Debian to additional risk.

Determining whether a specific application is likely to infringe on an
enforceable patent is incredibly tricky, and requires significant domain
knowledge in both the area of the patent and case law in the domain of
the patent (and always involves some amount of uncertainty). Multiply
that complication by the number of patent systems that Debian is
distributed in and the complexity is even higher.

Without that knowledge (which in my experience usually involves a team
of experts), it's challenging to weigh the risks of infringing.

If you have knowledge of violations or are concerned about a specific
patent, follow the policy and notify [email protected], not this
mailing list.
