I have a startup and I just sent via E-Mail some sample images to a family member who owns a small marketing and design company in the US. My parents had suggested it since we are on good terms with the person and we trust him. The images I sent are close to what the final product is intended to look like. The first e-mail I received back, within a couple of minutes after I sent mine, asked something to the likes of "Do you have copyright on any of the images or the concept?"
Obviously, I do not. It's the last piece missing in the startup. This got me thinking, however. Can he, in theory, copyright what I've sent him? Even though I created it, and he indirectly implied in the e-mail that he's not the content owner, can he attribute my own intellectual property to himself? Can he replicate what my startup does, copyright it, and make it impossible for me to build my own product? I am a Canadian citizen (residing in Canada), so I'm not sure if that makes a difference.
