Suppose we have a ring of invisibility.
This is an item activated by a command word, as a standard action, which give invisibility as the spell for 3 minutes, almost infinite number of times per day.
Now I ask. Can I wear the ring, turn it and then pass it to a teammate who activates it and passes it to another, and so on?
in substance, after activating the ring, the spell continues to work even if I remove the ring?
