Not at all. Proof is in recent history. How long took to steal the multi touch from iPhone without paying a single patent? Once is out, is everyones game. If the market demand it enough.
You can be the first one, and that should pay you enough. If you want more, or think it doesn't worth your time, let room for somebody else.
New tech doesn't need patents. Drugs are another example. The blank brand drugs sell less than Bayern in my country and IT'S THE SAME DRUG. But people trust brands. So you are still in business even years after the patent expires. You don't need this laws to preserve new tech from coming out, companys want the markets only for themselves as long as they can. That's it.
If you could copy a drug from day one, health would be a better business for everyone except a few, and those few will only make a little less money. They won't go bankrupt.
Yes master.
