English to French Law/Patents Law (general) institutions

The context is a first page (credits) of a publication:

"For the avoidance of doubt, by applying this licence the Commonwealth of Learning and UNESCO do not waive any privileges or immunities from claims that they may be entitled to assert,

=> nor do the Commonwealth of Learning and UNESCO submit themselves to the jurisdiction, courts, legal processes or laws of any jurisdiction."

I'm not familiar with such a vocabulary, what does that mean precisely and how would you translate it?
I tried with "ni le Commonwealth of Learning, ni l’UNESCO ne reconnaissent la compétence personnelle d’aucun tribunal, d'aucune cour, procédure ou loi d’une quelconque juridiction", (according to another entry here: https://www.proz.com/kudoz/english_to_french/law_contracts/1... but it seems quite assertive to me, as a complete neophyte regarding legal translation.

Thank you !
