The patent is a lot more restricting compared to the statutory invention registration yet, if your goal would be to share it around the world then you skill is simply settle for the latter option. So many people who had thought of an idea but did not get any patent and not even a copyright regretted it in the end because there will be some people who will steal your ideas by you and pass it well like it had been their very own. That's actually the reason why you may proceed through all of this trouble of registering your opinions and your inventions so the credit is up to you since you deserve it. In the end you were the individual that looked at it as well as conjured your ideas perfectly into a reality.
If you don't have the budget to get your invention patented and have it registered, contact companies that you think may be interested. They might be ready to sponsor you as companies look for new ideas anyways particularly when your patent companies is related to their business and definately will make them plenty of cash.
