Chinese technology giant Huawei has expanded patent licensing with global firms, as the company seeks new sources of revenue after being added to Washington’s trade blacklist in 2019.

Huawei announced the renewal of the patent license agreement with Finnish company Nokia on Friday, without revealing details of the agreement.

Nokia began booking licensing revenue from Huawei back in 2017, the latest extension reflects Huawei’s prowess which continues to grow despite U.S. pressure.

Earlier December, Huawei and OPPO also announced the signing of a global patent cross-licensing deal, which covers basic patents for cellular communication standards, including 5G standards. Huawei and Samsung Group have signed a similar deal on their respective standard essential patent packages.

In automobiles, the tech giant has reached royalty agreements with automakers including Audi, Mercedes-Benz and BMW, to add communications technologies to their vehicles.

This year, Huawei has signed or renewed more than 20 patent licensing deals in industries including smartphones, automobiles and telecommunications, Steven Geiszler, the company's U.S. chief intellectual property counsel, said late Thursday, according to Reuters.

Huawei's global patent licensing revenue was about $1.2 billion from 2019 to 2021, or hundreds of millions of dollars annually, Geiszler said. For the second year in a row, the company will receive more patent revenue in 2022 than it pays out to other companies, he added.

Huawei posted total revenue of 636.8 billion yuan ($191.11 billion) in 2021, a decline of 28.6 percent from a year earlier, as U.S. curbs on Chinese technology influenced its sales in places such as the U.S. and Europe.

Huawei CEO & founder Ren Zhengfei told the company’s intellectual property team to step up efforts to turn its vast pool of patents into revenue through “reasonable pricing”, according to a company memo made public in April.

For five straight years, Huawei has ranked first in the world in terms of Patent Cooperation Treaty (PCT) applications, said Alan Fan, head of Huawei’s IPR Department.
