And anyway, the nature of the rings was never important in the comics. The fact that they were ten rings from a spaceship, each with a different super power, was neat, but the fact that it was specifically that thing wasn't important. What was important was that The Mandarin had a means of physically confronting Iron Man that wasn't a suit of armor and was something he stumbled across and took for himself but didn't actually create or earn. Extremis served the same function in Iron Man 3.
