Hi Oleg,
my personal experience with Certicom's IPR disclosures is that they
focus on Elliptic Curve Cryptography. There were several IPR disclosures
on documents in the JOSE WG and some of them contain ECC algorithms.
The JWT does not list an ECC algorithm but the referenced documents do.
Having said that the two cited IPRs seem to be:
http://www.google.com/patents/US6704870
http://www.google.com/patents/US7215773
Take a look at it and make your assessment whether there is anything we
can change.
Ciao

Dear OAuth WG and Chairs,
Can somebody please comment the Certicom's disclosure below? If the
purpose of this disclosure is to inform us that JWT can be potentially a
subject of royalties and other possible legal actions, the value of
adopting JWT in the scope of OAuth 2.0 IETF standard would definitely
diminish and if this is the case shouldn't we consider replacing it with
something similar, but different, which would not be a subject of the
future possible litigation?
I'm not a lawyer and might not understand the statement below correctly,
so please let me know if/where I'm wrong. Please keep in mind also that
the popularity of JWT is growing fast along with the implementations, so
we need to do something quickly.
Thanks,
Oleg.
