In general terms, I agree, but when you have over 170 infringers and possible access to royalty bearing settlements, it is different. The manner that DM is proceeding indicates little resistence to their strategy so far.
We will know much more in a couple of months as the 19 infringer group concludes.
Exciting stuff any way you look at it.
