As Scwha has aptly mentioned, you'll have to disclose a LOT of information to a LOT of people, in order to find someone willing to invest money in your dream.

Therefore, it may make sense seeking patent protection. It is also a good idea from a technical standpoint, to do a related patent search, because you never know if your original idea has already been covered by another patent, although in a different form.

You'll be surprised at the number of patents that never make it to the marketplace, but are still there. If your idea does become viable, then the dormant patent holder could wake up and you'll find yourself on litigation.
