If I make a mpeg4 iso codec compatible and I use a private fourcc
(codec identifier), this won't make me guilty of stolen code...

If you reverse engineering a format and manage to create an
application that create a file, will you let's comment of proprietary
application or change comment referencing to your software.

For this reasons I didn't see it as a strong indication but only some hints.
