A physician of my acquaintance patented an invention, and my then employer contracted to help him commercialize it.
A half dozen proof-of-principle prototypes were distributed to test sites around the world, but the data they collected was worthless, since the basic machines didn't run consistently, and the data was recorded only as plots on graph paper. That was the state of the project when I arrived, five years in.
The doctor asked me how long it would take to make one that was suitable for the market.
I told him ten years from that date, given the normal product development process in that company, such as it was, and the strength of the company's commitment to the project.
The doctor admitted later that he was shocked at my estimate, and thought I was both crazy and incompetent.
A little less than ten years later, with me working part time on the project (all that was allowed), and stealing resources from other projects, we had built six identical pre-production prototypes that ran consistently and reliably, and their results tracked one another perfectly. They were probably too expensive for sale at a profit, but they were good enough to serve as a basis for value engineering, and to distribute to customers for evaluation of the technology.
Our crack Marketing department then decided that there was no market for the device, and they would vehemently oppose any effort to proceed further.
I was there the day the prototypes went into the dumpster.
For maybe a couple million dollars total, the company kept the device off the market for fifteen+ years.
I couldn't shake the thought that the delay was their intent all along, which was inexplicable to me, because it didn't compete with any of our products, and in fact used one of our products as a major component.
The doctor thought the technology would provide a very early detection mechanism for a worldwide pernicious disease, but he couldn't prove it with the data collected by the early primitive machines, and he was barely on speaking terms with the company by the time my prototypes were completed.
The doctor never got a dime out of the invention.
If you were expecting a happy ending to the story, I apologize.
