Today, the story of three inventions. The first, the sewing machine, was created by a selfish and ambitious inventor who wanted all the credit and was willing to fight a war for it.

The second, a more modern invention, was made by an Italian inventor who wanted only to connect the world through video, so “evvvvverybody can talk with evvvvverybody else.”

And, a third invention that tied them both together across more than a century. The patent pool.

How do people get motivated to invent, and how do they get rewarded for their ideas? Usually through a patent. And, when the thicket of patents becomes too thick, how do we simplify, and make it so inventors can work together? The answer will involve bitter rivals, a sewing machine war, the nine no-no’s of anti-trust, and something called a gob-feeder.
