That is the tough one. Lots of smart, hard-working flow-bench artists have come up with ideas that were promptly adopted by engine manufacturers on new models. But very few have ever been paid for anything other than their labor. One of the first rules of earning real money is, “Never sell your labor.” How does the shape of a port become protected intellectual property and then how do you sell it? I know two men who spent 10 years of their lives promoting a unique automotive technology. When their years in hotels and airliners finally landed them a solid buyer, negotiations broke down when they discovered that the buyer’s many delays were just cover for a legal team working to break their patents.
