If you look at their site, it turns out that they have licensing and/or do-not-sue agreements with Apple, Micron, and a handful of other HW vendors. I can just imagine the sales pitch...
"Dear [CEO of micron]:
We are a prosperous and enterprising intellectual property company specializing in maximizing the profitability of 3rd party IP portfolios. If you will allow us to purchase your patent IP, specifically (...), we will grant you a ... license to continue to use your patents. We will also pass on to you x% of any lawsuit and royalty revenue we make with said patent.
By the way, you are currently infringing upon our patents (a, b, and c), so if you do not accept this proposal we will simply get our money in court. Either way, we win. You lose."
And IIRC, that was about the wording that the communist used before the president told him, "Get off of my plane."
