That is true! When I was interested in manufacturing and distributing sampling equipment for marine science and fresh water. It was suggested I contact manufacturers in Taiwan. The situation would have been the same in terms of submitting specifications and blueprints for quotes `irrigardless of patents or licenses. In the long run there were no protections as to marketing and manufacture. It would have been a costly experiment without protection. The Chinese offer "knock offs" of expensive watches Etc. such as Rolex diving watches without regard to patents or license, they are thieves at best.
