Do I own copyright if I own a copyright work?

Not unless you are the first owner of copyright or copyright has been transferred to you. Copyright exists independently of the medium on which a work is recorded. For example, if you have bought or inherited a painting, you only own the copyright if that has also been transferred to you.

Where a copyright work has been published, many copies may have been sold to the public, for example books, CDs or software. However, if you have bought one of these copies, you have not bought the copyright that exists in the content. So, you cannot do what you like with it without the permission of the copyright owner. The copyright owner retains all the economic rights in the copyright work. However, if you have a copy that was sold anywhere in the European Economic Area (EEA), you can sell it to someone else without infringing copyright.
