Mossberg dived into the controversy around Myhrvold's venture, which has been called an institutionalized "patent troll." Myhrvold says, "We invest in ideas, not the realization of it." He says, "We recruit inventors before they have an invention."

"And then you own it?" Mossberg asks. "Yes, but we pay the inventor.&… Read more
