Patents should be valid for one year only, to give a head start to whom had the idea and invested developing it.

That willl give them enough time to build a brand (iPhone, Viagra) then it is all open season and everybody can copy and improve on that idea to get an edge, investing their own resources (Zune, Cialis) whether they fail or not is up to the market.

You can't blame people for you being a great researcher and a poor marketer.

People will reward who can be both.
