Hiya,

One way to handle this might be to add the winners as
co-authors on the Internet-draft. In that case, the
draft boilerplate text says that you're following the IETF
IPR rules and hence would have filed an IPR declaration
if one was needed. And if none is needed, we'd be done.

I'm sure we can figure other options but the above would
be easiest from the IETF point of view.

Cheers,
S.
