Unless one has the resources to have a patent firm check for previous patents and get your brainchild patented, and presented to potential manufacturers or investors, one has little chance of moving forward with his creation.
I worked with a research group for a major company, every little idea we had was checked for patentability. Not easy for an individual unless he HAS a private business on which to base his creations.
