From the Ron Zapata article:

"TPL offered Patriot $7.5 million for the portfolio, an offer that was declined based on Patriot's estimated worth of the portfolio at $1 billion. By June 2005 Patriot dropped its complaint against TPL and entered into an agreement to jointly control the patents."

Considering TPL/PTSC has collected just north of $200M, that leaves $800M on the table to be split between roughly 380 "on-notice" infringers. That's only an average of $2.1M per license. At the same time, if collected over the next 5 years, that's an average of $80M / year in revenues for PTSC, which ain't bad for a 5 person company.

Let's hope that the original PTSC estimate was WAY low!
