SK Hynix took the deal because the patents Netlist had were valid at the time. They are probably remaining silent and watching now. If everything goes the infringer's way and patents get invalidated (as is the trend by the corrupt PTAB), they won't have to renew their contract with Netlist and can use the IP for nothing once their contract expires.
they may not be able to testify on netlists behalf on the grounds of settling out of court but i may be talking out my backside on that, but i like the idea.
