Phillip Rogaway<rogaway@cs.ucdavis.edu> Sat, 27 February 2021 02:46 UTC I can confirm that I have abandoned all OCB patents and placed into the public domain all OCB-related IP of mine. While I have been telling people this for quite some time, I don't think I ever made a proper announcement to the CFRG or on the OCB webpage. Consider that done.
