Don't get too excited about Amazon's drone delivery patent
"Like with most patents, the specifics don't matter -- Amazon's lawyers wrote down as many possible ways of building such a thing (again, compressed air, steering fins) so Amazon has a better chance of defending the idea in court.Ready for me to rain on the parade? The other thing about patents, particularly ones that have been granted, is that they describe old ideas -- ideas that may have been discarded.
Amazon applied for this particular patent in June 2015, and yet Amazon's first drone deliveries, in December 2016, didn't use such a system."
