No. This is a common misconception. The patent system is there to give a temporary monopoly on an implementation in return for allowing it to be public domain later - and disclosing the knowledge now, not later, so that additional innovation can proceed. The only problem is that the term of the monopoly is selected to support mechanical engineering growth rates of the 19th century, and we're stupidly trying to apply it to entire industries that rise and disappear more quickly than that. Read some patents from other fields - they typically protect and disclose stuff that really took some work to figure out. That's the point. One-click ordering, though? That's just plain bullshit. Anybody could implement that.
