Can ‘herd immunity’ beat patent trolls?

Readers may have heard something about “herd immunity” lately, but probably not in the context in which Ken Seddon uses it. Seddon is chief executive officer of the LOT Network, an alliance of companies devoted to curbing the threat of so-called patent trolls. The idea is that when a company joins LOT, it grants all other members a free licence to any of its patents that might later be sold to a patent troll.
