I could be way off base, but I see it this way.

We had a good case:
1) we said, trustwave, you’re selling products that infringe on our patents.
2) they said, no we’re not.
3) we started the court proceeding and started research, sharing information etc.
4) we got to a point to where they finally said, okay okay fine, we see now that the products we were selling were infringing on your patents... but, it’s not our fault. We were just selling products from DUO (oem)... so, it’s their fault.
5) we said, hhmmm, thanks for that - you’re right, it is DUO’s fault that we’ve been coming after you... it’s their product, it’s their problem...
6) ring ring...hey, DUO, it seems we have a problem...

All my opinion of course... just seems to feel good in my head
