Appears there is much more to this story, I was trying to find out the merit of the patents, and from my brief 10 minutes of searching, This is the third trial of this sort, First 2 were against Samsung and Google. Hynix is not being sued because they are paying royalties(Settled out of court for pennies and are now sharing patents in cross licensing scheme). Samsung was paying Royalties in the past but stopped. It reeks of collusion of large corporations to snuff out valid IP Claims and this is lawfare to avoid it and attempt to destroy netlist. If this was Obvious art/unpatentable I don't see why any of them would have paid royalties in the first place.
Its all very muddy and I wish there was more discussion around the actual foundation of the patents. Based on the staying power of Netlist against these goliaths, there is obviously some merit to their patent claims.
Here is a link to the actual 912 patent,

Appears the story goes back to 2009, Google applying tech without licensing, admitted to use in court documents. This patent has survived many reviews thus far, see how the appeals and continued lawfare change the damages.
