BT's research arm, BTexact, is hoping to generate revenue in the US by licensing some of its 14,000 patented technologies.
The move, in conjunction with patent promoter ipValue, comes 18 months after the embarrassing revelation that BT owned the US patent to hyperlinks, a key internet component that it had failed to commercialise.
BTexact has given ipValue a six-year exclusive contract to license its existing and future patents to corporations based in the US and Canada for technologies in telecoms, multimedia and wireless, the company said.
"Intellectual property is a massively underdeveloped area," said Peter Wheeler of ipValue's parent company, iFormation. "Eight or 10 years ago licensing activity was relatively modest, but the way people view intellectual property is changing dramatically."
Stewart Davies, chief executive of BTexact, said that the move was a "portfolio of knowledge", and that BT and ipValue will share the received revenues which they hope will raise $100m (£69m) a year by the time the contract is up.
