Are there any techniques in Brazilian Jujutsu that AREN'T in Judo?

I've been answering question based on the knowledge that Brazilian Jujutsu came from judoka Mitsuyo Maeda's teachings, and that it just focused on the ne waza part. Are there any techniques that the Gracies, or any subsequent practitioners of Brazilian Jujutsu, developed that were not part of the unified system of Judo created by Jigoro Kano and brought to Brazil by Maeda? If I have been answering questions with incorrect knowledge, I apologize.
