The early tortoise always gets beaten by the hares who start later. Something like that – think social networking and how Friendster was overtaken by MySpace and then Facebook. Or, indeed, virtual worlds, where pioneer Worlds.com lost out to Second Life, Habbo, Club Penguin and a host of other more nimble firms that launched in its wake. However, Worlds.com isn’t taking that lying down – it’s suing the makers of both Second Life and World of Warcraft, claiming they infringe on its patent for a “scalable virtual world with thousands of users”. If these cases end up in court and Worlds.com wins, it’ll have a huge impact on the hundreds of other virtual worlds battling for users.
