If I'm correct doc, dooku was going down an evil path but was not yet a sith.
He was seduced by the dark side but didnt become Sidious' apprentice until Maul was killed by Obi-Wan.

History of the Sith
The book also gives a history of the Siths. And that the Siths wiped each other out and only one survived - Darth Bane. He developed the idea of only two Siths at a time to prevent internal problems. Lucas has said: "One of the themes throughout the films is that the Sith Lords, when they started out thousands of years ago, embraced the Dark Side. They were greedy and self-centered and they all wanted to take over, so they killed each other. Eventually there was only one left, and that one took on an apprentice. And for thousands of years, the master would teach the apprentice, the master would die, the apprentice would then teach another apprentice, become the master, and so on. But there could never be more than two of them, because if there were, they woud try to get rid of the leader, which is exactly what Vader was trying to do, and that's exactly what the Emperor was trying to do. The Emperor was trying to get rid of Vader, and Vader was trying to get rid of the Emperor. And that is the antithesis of a symbiotic relationship, in which, if you do that, you become cancer, and you eventually kill the host, and everything dies."
Dooku escaped, with the Jedi aware of his succumbing to the dark side, but yet still unaware of his Sith allegiance.
He was seduced by the dark side but didnt become Sidious' apprentice until Maul was killed by Obi-Wan.
Following the death of Darth Maul, Lord Sidious sought out another apprentice. With his plans quickly coming together, Sidious did not have time to train a new apprentice from birth. He instead turned to the Jedi. Focusing in on a powerful, and unsatisfied Jedi, Sidious recruited Count Dooku and quickly turned him to the Dark Side.
