As far as we have seen, Sasuke has never copied a jutsu. We know he learned the chidori from Kakashi, but it is never directly stated that he did so using the sharingan. We also know he emulates Lee's fighting style, but he could have done that without the sharingan as well, though it would be harder (It's not like he was copying any moves, just style).



There are a variety of moves that he could have copied by now.

Zabuza's water clone and mist jutsus
Naruto's kage bunshin
Orochimaru's wind attack (he used it during ep 30 and one of the earlier eps. The first one separated Naruto from his group, and the second one was dodged by Sasuke to do his flying pile-driver).

Oro also seemed to use a jutsu right at the beginning of his fight with Sasuke (It kind of made a shockwave just as Sasuke came charging in). I just assumed it had something to do with his speed there, though we all know that a ninja at his level doesn't need a jutsu to run circles around a genin.



I can only guess that Sasuke's sharingan is not developed enough to copy jutsus without investing a significant amount of time into it. Either that, or he's storing the jutsus away for future use.
