Duarte, who filed a lawsuit in August against Brown, claiming that his bodyguard violently beat him up when the two singers and their entourages got into an heated confrontation outside Westlake Recording Studio in Los Angeles in January.
Duarte says he suffered a huge amount of physical and emotional pain as a result of the confrontation, reported TMZ online.
Duarte has submitted an itemised list of what he is seeking damages for in new court documents, that includes USD 1 million for pain, suffering and inconvenience, and USD 1 million for emotional distress.
Brown is currently undergoing a court ordered 90-day stint at a live-in rehabilitation centre to focus on his anger issues. He filed documents to counter-sue last month, in which the 24-year-old singing star claimed that Duarte provoked the fight by threatening to kill him.
He also accused Duarte of kicking and punching him, and insisted that he attempted to avoid the altercation "with the aggressive and hostile Duarte."
It was previously reported that Brown fled the scene straight after the fight, while Ocean stayed to speak to police officers.
