Apple Inc and HTC Corp announced on Saturday a global patent settlement and 10-year licensing agreement that ends one of the first major conflagrations of the smartphone patent wars.

Apple and HTC did not disclose specific terms of the deal. In a joint statement, Apple chief executive Tim Cook said he was glad to reach a settlement.

"We will continue to stay laser focused on product innovation," Cook said.

Since Apple first sued HTC, its smartphone patent war has engulfed competitors like Samsung Electronics Co Ltd and Google's Motorola Mobility unit.

The iPhone maker won a $1.05 billion verdict against Samsung in August, while litigation against Motorola has failed to produce any decisive wins.

However, Apple had the most success against HTC when it came to using litigation to actually disrupt the flow of products into the crucial US market.

Late last year, the US International Trade Commission ruled that HTC had infringed upon one of four patents Apple had disputed and imposed a sales ban on some of the Taiwanese maker's phones.

Though HTC said it had devised a technical workaround to Apple's patents, the company announced in May that shipments of its phones were being held up by US customs officials.

Once one of the industry's high flyers, HTC has been badly hit by competition from Apple and Samsung. Last month HTC forecast a 14.5 per cent fall in revenue in the fourth quarter from the third, worse than analyst forecasts and the second straight quarterly decline this year.
