David B, To Clarify your point. Patent Laws or the idea was first introduced in Medieval Venice, then England as you say. Germany still had no idea about them.
[ Venetian Republic ]
Patents were granted for inventions already in 1443, and the text of the oldest patent law in the world, officially announced as “Inventor Bylaws” was created in 1474.
[ England ]
The text of the patent law, known as “Monopoly Act”, was created and the law was enacted in 1624. This law clearly defined basic concepts which are still influencing interpretation of patents to present day.
[ Germany ]
Germany enacted a comprehensive Patent Law which was based on the principle of mandatory examination, the first such system in the world, in 1877.
If there were no patents in the 1700s, why would anyone pay Bessler 20,000 pounds? They would have just as much trouble protecting their investment as Bessler had protecting his idea.
That’s why he had an almost impossible task of selling his invention!

I am currently working on an idea which utilizes a much more overbalanced system. Still buying parts at moment…
