Incorrect. The Berne Convention of 1886 protects ALL writings and Artistic Works the moment it is written. The Berne Convention has also been used in Copyright Law cases from a technology stand point. Ever heard of a concept being scribbled on a piece of paper and then later turned into a product? The moment they put pen to paper, it's intellectually copyrighted.
The Berne Convention and the Universal Copyright Convention (UCC) was adopted at the Geneva Convention in 1952 and amended in Paris in 1971. The UNESCO (United Nations Educational, Scientific and Cultural Organization) took it one step further to cover more states and countries in the world, but since nearly every country or state is part of the World Trae Organization (WTO), they too also agree to the Berne Convention and the UCC.
I've been dealing with copyright infringement since 1994 in one form or another, and the moment you put your concept to paper (or in this case, the internet), it becomes your intellectual copyright.
