So, here's the deal, I've got an idea, and I want to protect it. By that, I am not talking about piracy protection, more like content protection.
'Content' is what is created from ideas. 'Content' is protected by copyrights.
Say there's a hypothetical scenario, a fiend hacks into my files and steals that which I plan to put into development, and that thing finds its way into big bucks publishing house and they end up hoarding million for something whose concept I conceived... how can I protect myself from such a scenario outside of making a patent, it being under lock and key?
You can't patent, trademark, or copyright ideas. Ideas can't be owned.
Only your specific implementation or design of that idea can be protected.
If your implementation or design gets stolen, and you can prove it through your documentation, then sue the crap out of that company. But if it's under lock and key, you won't be able to prove that your idea was created beforehand.
Apart from that, keep your idea to yourself, and if you must talk to someone else (say an investor), make them sign an NDA. If they violate the NDA, sue them.
Ofcourse, if your idea is generic enough, chances are other people also have the same idea, and someone might get around to making it before you. Or even after you. When this occurs, don't assume that they stole "your" idea. Many people come out of the woodwork and start suing big successes like Star Wars and Harry Potter and Twilight and Facebook and whatever else, claiming (and even proving) that they had the "idea" first, or even wrote and published a book or game that's similar. Doesn't matter. If one human can have an idea, hundreds of other humans might get the same idea independently. "Boy goes to magic school" (Harry Potter) isn't owned by anyone. "Boy is chosen one" (Harry Potter and Star Wars and a bajillion others) isn't owned by anyone. Only the execution/implementation of the idea is owned.
Same with names. If someone else happened to use the name "Harry Potter" in a book before JK Rowling did, that doesn't mean JK Rowling stole the name. Heck, there are more than one real life people with the name Harry Potter. That doesn't mean JK Rowling stole their birth name either.
