Taiwanese smartphone maker HTC has signed a patent and technology collaboration agreement with Finnish phone giant Nokia to end all pending patent litigation between them.

Under the deal, HTC would make payments to Nokia and the collaboration would involve HTC's LTE patent portfolio to further strengthen Nokia's licensing offering, HTC said at the weekend.

The companies would also explore future technology collaboration opportunities, HTC said, adding that the full terms of the agreement were confidential.

"Nokia has one of the most pre-eminent patent portfolios in the industry," said HTC general counsel Grace Lei. "As an industry pioneer in smartphones with a strong patent portfolio, HTC is pleased to come to this agreement, which will enable us to stay focused on innovation for consumers."

Nokia said it was "very pleased" to have reached the settlement and collaboration agreement, with chief intellectual property officer Paul Melin saying it "validates Nokia's implementation patents and enables us to focus on further licensing opportunities".

Nokia started its patent litigation against HTC in 2012 and filed more than 50 lawsuits worldwide. HTC was found to be in violation of four Nokia patents.

Technology giants have taken to routinely pounding one another with patent lawsuits. Apple has accused HTC and other smartphone makers using Google's Android mobile operating system of infringing on Apple-held patents.

HTC and Apple were locked in more than 20 cases worldwide until they reached a global settlement in late 2012 to end all outstanding litigation between them.

HTC sells its own smartphones and also makes handsets for a number of leading US companies, including Google's Nexus One.

In the third quarter of last year, HTC swung to its first net loss of US$101 million since listing in 2002. It reported a net profit of US$10.3 million in the fourth quarter.
