Excellent presentation using a pdf image to add impact on the patent topic.
I am working on a family ancestral line that has some rich stories of the earliest days of industrial revolution. Found some very inventive people. This is in England. They did breakthru things for decades, Here is the twist. This was a time of rapid concept evolution. On one of the most sought after mechanical inventions, a cousin had the first demonstration of mechanized cotton thread making.....then got spanked when he missed out on the patent filing, no grasp of the legal process. Others were wiser.
Another had built the first iron framework bridge in the world. Just never considered it for a patent.So they must deserve the badge of inventors, but they were broke inventors. no patents. that is a neat subcategory.
Edit: I did forget something about this 2nd individual. He did get credit for inventing spring scales. Did sell that. This application initially was of great value because someone could get the horse or ox drawn carts pulled on top of this scale and determine exactly what weight was in the cart or wagon.
