Bill,
The IETF stays strictly out of such discussions. It is entirely
up to each implementor to decide whether or not the claimed IPR is
valid and to make arrangements with the IPR owners if so.
Please see RFC 3979 for more details, and see
https://datatracker.ietf.org/public/ipr_disclosure.cgi
for all current disclosures to the IETF.
Sorry but this is something your company has to resolve
for itself.

Hi,
We are implementing an Ethernet protection ring. Then we found there is
an information RFC3619.
It is submitted by Extreme network and its IPR is protected by the
company too. We also found there are
some patents filed by Extreme. In addition to EAPS, we also found there
is MRP from Foundry, EPSR from
Allied Telesyn, ERP from Siemens. They are all like the same. Isn't it
legal violation? We tried to contact
Extreme before. But there is no concrete response on the licensing
process. Any comment is welcome.
Thanks.
