what do i need to protect an idea/product?

Question

I've looked online and since I'm only 13, I don't really understand the difference between a patent, copyright, and trademark. The ideas are all for controlling an MP3 player with more ease, but they can also be used for other products like phones or pdas. I want to be able to sell these to a company so they can start making it, but I need them to be protected or they'll just steal the idea when I contact them. And I know this is a bit of a seperate question, but what companies are out there that can help me get a patent and will do it for free or cheap? (I'm only 13, so I'm on a bit of a budget)

Answer 1

I think you'd need a patent, not a copyright or trademark.

You need to document the idea and show how its different.

Down side is, you really need to find a patent attorney to do a patent search etc. I suppose you could risk it and simply file the patent-- but you'll need help in writing the patent application as I doubt you'll be able to do it on your own.

Answer 2

I am no expert, but I was told if you place detailed plans,sketches, etc. of your idea in an envelope and send it by registered mail TO YOURSELF, it provides proof that the idea is yours and the post office date is an OFFICIAL time record.
