Dear Vint,

I'm sorry for the delayed response.

Camellia essential patents can be used at no charge by any Camellia user 
without concluding such royalty-free licensing agreement hereafter.
And, IPR for IPsec and TLS have been published as a following URL;

o IPsec
  https://datatracker.ietf.org/ipr/771/
o TLS
  https://datatracker.ietf.org/ipr/41/

Regards,
Satoru
