So are prescription drugs. And other products with patent protection.
Patent protection does NOT regulate business. It protects intellectual property rights. Without patent protection there wouldn't be any new drugs.
I never knew either of my two grandfathers. Both died from what is now easily cured with a $5.00 drug prescription (though they were called "Miracle Drugs" at the time of their invention). I sure hope my some day grand children will get to see their grand father. They probably will, unless some politicians eliminate drug development by altering patent protections for new drugs.
