Just on a general policy for handling things like this.

Firstly, never discuss specifics on a mailing list.  Patents are a
really tricky area where advice in confidence is needed and lack of
confidentiality usually only benefits the patent holder.

Secondly, vague threats (like this) can be safely ignored.  Thanks to
the terms of the GPL and the specific actions of OIN, we legitimately
have licences to a vast pool of patents, so we should assume for every
vague threat of the existence of a patent that we do legitimately
possess a licence until the threat is made specific.

Finally, if the vague threat becomes specific (which means citation of
patent by number and claim) you need to engage the resources we have at
our disposal to investigate.  Likely it will be OIN resources that do
this investigation, but the way to begin is to start with your
corporate counsel for contributions on behalf of a company.  If they're
on behalf of you as an individual, you can begin with Counsel which the
Linux Foundation will provide.
