From The Guardian:
US entrepreneurs cash in on Occupy movement
T-shirts, coffee mugs and other merchandise being offered on campsites that have sprung up in cities across country
The revolution could be trademarked in the US as more entrepreneurs seek to profit from the Occupy demonstrations.
T-shirts began to appear days after the first protest on 17 September, a march through lower Manhattan. Now T-shirts, coffee mugs and other merchandise are being offered on the campsites that have sprung up in cities across the US. The US patent and trademark office has received a spate of applications.
Ray Agrinzone, a clothing designer, who launched theoccupystore.com and has received hateful tweets and emails, said: "There's nothing wrong with turning a profit."
