Samsung and Hynix accounted for 24% and 11% of TSRA's 2014 sales, respectively, with Micron likely to account for over 10% of TSRA sales in 2015. All for DRAM packaging license.
I am trying to find out when the Patents for DRAM packaging expires...it appears to me that the main Patent expired in Dec. 2014 or is this 20 years and they have until Dec. 2017?
