Canon, the Japanese consumer electronics group, is clear to launch a new type of television after winning a patent lawsuit that has delayed its progress for more than three years.

Nasdaq-listed Applied Nanotech, which had sued the Japanese company for illegally sublicensing its patents, told the Financial Times that it had decided not to appeal to the US Supreme Court. "It would probably be a futile effort," said Douglas Baker, Applied Nanotech's chief financial officer.
