- the inventor invented without patent protection
- many competitors entered the market, making the product cheap
- the inventor's company is still alive and well
I swear, if I didn't know better, I'd say that it was written by a disgruntled employee. There are overtones of sarcasm too - it completely reverts the logic as to why the patents are supposed to be a good idea (i.e. they tout "maximum profits for the inventor" rather than "public good"). It ends with "the inventor discovered our legally sanctined monopolies and is a happy monopolist these days". Hilarious!
