My father worked as a metallurgist for [GIANT INTERNATIONAL CHEMICAL COMPANY] for almost 30 years. There was one inspection protocol he had to go through once every couple years that was on a particularly dangerous piece of equipment that put his life and health at significant risk. After having done this inspection multiple times over the decades, he came up with a better way to do it. He sat at his drafting table for a couple months and designed a tool that makes that one specific job really easy. Due to the stipulations of his employment, [GIANT INTERNATIONAL CHEMICAL COMPANY] owned the idea. They patented everything, manufactured it, and even sell it to other companies that do that same type of inspection. In the late 90's, the tool cost about $200k. They never even associated my dad's name with the tool, let alone gave him any reward for creating something that went on to be the industry standard. I think they let him play golf with the plant VP and that was about it. He was never bitter about it because he knew that if he invented something while employed there, he couldn't own it. He did it because he wanted to contribute to the advancement of his trade.
