I can appreciate your optimism, however, I cannot recall a time when I have seen a reference to over 600 infringers. I seem to recall David Pohl and perhaps Leckrone making reference to 400. The only time 600 comes to mind is in the following press release from TPL whereby they speak of over 600 prior art references reviewed by the USPTO

Also, let's not forget all those TPL expenses which will effect the amount finally realized by PTSC.

Corrections welcome
