Daniel Düsentrieb has it easy: His genius provides him with inventions, and he doesn't have to worry about financing and patent law. That's nice, but unfortunately, reality is a bit more complicated: Alexander Rapp shows you how to work systematically as an inventor, how to evaluate ideas, implement them, and finally test your work thoroughly. He also explains the difference between a patent and a utility model, as well as how to best protect your invention. Finally, he offers suggestions on how to monetize your brainchild through investments and licenses.
