Correcting the conclusion
'Nazer said Amazon would be unlikely to try and use this patent in court yet, and it's more likely something that the company can just add to its existing portfolio to use as a weapon when it has reached peak innovation and wants to stop more agile competitors from eroding its market share.'
The problem with stupid patents isn't necessarily that many will immediately or ever be aired in court, it's that the very threat of them stifles innovation and dramatically increases the barrier of entry into technology markets so that bloated incumbents can extract profits at the expense of the public good. The need to hold a war chest of vague patents to do battle with makes it much less likely that a new Microsoft or Oracle will rise up to slay the existing monoliths and therefore much more likely that the current ones will continue to extract excessive license fees well past their natural expiry date.
