As I recall UOP holds the patents for Unocal's "California forumulated" RUG, and has played hardball with other refiners in licensing negotiations. After reforumulated RUG was mandated, only Unocal could come up with a working formula that was economically feasible. Chevron tried to get it by buying Unocal and screwed up, which they do a lot.
