Not legally, but you have to prove you were the original creator and how would you do that? Dates on computers, emails, and etc can be easily modified, so they wouldn't help.Can't someone take your idea and then copyright it themselves. Then sell it?
That makes a good point! So I definitely need to keep a filing system to prove when i started and so on.In the movie (and the short story I'm sure, but I didn't read it) Secret Window, the protagonist requests an old magazine article that proved he had created a story that the antagonist claimed he had written and the protagonist had stolen. The magazine article was prior to the date the antagonist claimed he wrote the story, so it would be considered proof that he hadn't written the story. Just thought I'd toss that out there, the movie was kinda bleh and should've just remained a short story (or been an hour long made for tv movie, but then it wouldn't have Johnny Depp, who did a good job, just movie didn't have that much substance).
In a way, yes, you do. Copyright is not created by filing a form. Here's what the copyright office says:Do you HAVE to copyright your artwork that you have printed on your companies t-shirts?
Ideas are not copyright protected. Only the actual work, art, play, book, etc. resulting from that idea is copyrightable. So yes, anyone can take an idea and use it. For instance, Einstein's E=mc2 came out of the ideas of other people. Einstein put it together in a way that hadn't been seen before (he made it simple).Can't someone take your idea and then copyright it themselves. Then sell it?
