Charts for other years aren't much different.
Lots of manufacturing process patents among the numbers.
So here's the difference between Apple and Samsung:
Apple makes a narrow range of products and patents technology for UI, software, hardware and manufacturing specific to those products. A collective sample of all of Apple's physical products will fit on a modest sized table.
Samsung builds from the component level to ships, and the patents reflect that. It doesn't necessarily mean that Samsung patent quantities have any effect on Apple at all other than via components that Apple specifically purchases from Samsung.
On the other hand, it is probably true that Samsung is not well supported with patents for UI of the quaility of Apple's or Microsoft's. The question unanswered is what patents Samsung will use against Apple and how much weight they will carry.
Happy to see that Samsung is doing so well with all of their businesses, but that doesn't change the fact that Apple gets a better return on investment nor that Apple is building a pile of cash.
