Facebook Finds Itself in Strange Faceoff With Faceparty Founder

A social media pioneer tried to convince a judge there’s a big mistake in how Facebook Inc. came to acquire the rights to the word “face” more than a decade ago.

Andrew David Bamforth, the co-founder of Faceparty, a British site that enjoyed a brief heyday in the early 2000s, claims he was mentally incapacitated for 12 years, including in 2008 when he signed a trademark rights agreement that Mark Zuckerberg’s company relied on to build the world’s biggest social network.
