Stateless strategy patterns?
Factories?
Finite state machines (no need for state within state)?
Actually, most of the design patterns I can think of make sense in
some stateless form, because the concrete *type* of the object is
often enough to play the role of a state at some higher level.
Interfaces are more about operations than about data.
