It's an interesting question indeed. Whereas PTSC loaned and advanced $2M to TPL, and then turned around and sued them, effectively giving TPL the funds it needed to pay the legal fees to defend itself against PTSC.

In contrast, TPL withholds money it has agreed to pay Moore, Brown and Nielsen, effectively starving them of money they might need to pay the legal fees to pursue TPL.

Different business strategies. Based on what PTSC tells us, it doesn't take a huge leap of faith to figure out who's has worked best.
