In patent wars, it's seldom you see the bigger companies filing litigation claims at the aggressors. However, recent movement on this front has caused two patent trolls to have a change of heart, as both dropped patent infringement lawsuits against Overstock.com, a popular discount online shopper retailer.

So what did Overstock.com do to get the trolls to back down that other victims of litigation claims aren't doing? Apparently, the only difference is that the company fought back. While Overstock.com has more means and legal budget to fight the likes of patent trolls, the company is crediting its wins on spending its legal budget in defense in abusive lawsuits and not on unjust settlements.

“Patent trolls find us unappetizing,” Mark Griffin, Overstock.com's senior vice president and general counsel said. “While we have the highest respect for intellectual property rights, we don't settle abusive patent suits — we fight.”
