The only time someone will NOT copy you, is if the market is not worth it. But this is by definition a market that you should not play in.
Look at markets that are worth it (e.g. cloud computing)- they have products from different companies with exactly the same features.
In general, I am not sure what you are proposing. Let me publish my ideas for free, see someone copies them, and that be happy that I got it right?
