master66,
My first device was a holding and insertion tool for a solid state comp. By employment agreement the company held all rights. My total reward was $150.00 value to company aprox. $35,000 They had all the money and all the Legal staff.
The second device was a cutting tool, My out of pocket expense was aprox. $3,000 After one year, I received a certified letter stating I had to show the ability to manufacture and market the product or loose the rights. I tried to raise money for the project and failed to get any investors.
The third was an opening device, which costs $1,200 out of pocket expense, and after completed, Had no money left to market. Since that time five other companies are making the product, because they had the ability to produce and market.
The fourth was a core hole fire seal device, again pre employment contract, however this company treated me very well.
Stay with it, inventors are not instant winners.
