Let's say this research costs 1 million dollars, and the company bankrolls this via a loan. They build it and are successful, and begin paying it off.
Their competitor copies their idea, and exploits the fact that they have more capital and less debt to buy up more of the market, and end up the winner.
So, under a zero protection scheme it is optimal to wait until your competitor invests in research, and then just steal it. Which is what happens on a geopolitical level where there is no feasible enforcement possible.
