An interesting topic. I hold three patents, and will probably get a few more before my career is over. I was really excited about the first one. It's sort of like a rite of passage. But, the business side of things dampened my enthusiasm after awhile.
Speaking for the side of the big corporation (which is how I got mine), there are many sharks swimming in the water selling bad science and stealing good ideas. A defensive strategy is not all bad. I helped my company form a strategy in China to protect our technology. The U.S. is pretty law-abiding compared to much of the world. Look at what has happened to the music industry in Asia.
But, I do understand how tough it is for the small guy with an idea to be heard. The only advice I can give is not to expect to be "discovered". Work hard, and work your way into a company that has the clout to make your ideas happen.
