It's all bit complicated but, yes, anyone can publish copies of RFCs,
including translations into other languages. (See
http://trustee.ietf.org/license-info/archive/IETF-Trust-License-Policy-20091228.pdffor
latest provisions.)
Patent questions can be even more complex but, generally speaking, anyone
involved in the IETF process should make their claims known. See
http://www.ietf.org/ipr/. (It is always possible that there are those not
involved with the IETF process who have patent claims.) Depending on your
definition of "open", no, not all protocols approved by the IETF or
documented in RFCs are unencumbered.
Thanks,
Donald

Hello, I would like to clarify a doubt about the RFCs
Copyright The IETF allows you to copy, publish RFCs?
All protocols that are part of the architecture of TCP / IP are open?
Thanks, Victor

“Encarada do ponto de vista da juventude, a vida parece um futuro
indefinidamente longo, ao passo que, na velhice, ela parece um passado
deveras curto. Assim, a vida no seu início se apresenta do mesmo modo
que as coisas quando as olhamos através de um binóculo usado ao contrário;
mas, ao
seu final, ela se parece com as coisas tal qual são vistas quando o
binóculo
é usado de modo normal. Um homem precisa ter envelhecido e vivido
bastante para perceber como a vida é curta”.
(Poema de Arthur Schopenhauer)
