Critical 'sensing' systems could have military applications and Huawei is active in a European group that includes Apple and Interdigital.

Nevertheless, US authorities have been worried about China's influence over 5G development. After playing a relatively small part in 3G and 4G, Huawei emerged as a major 3GPP force during 5G standardization, and several analyst reports have subsequently ranked it among the biggest owners of patents, alongside western vendors such as Ericsson and Nokia. It invested about $22.6 billion in research and development (R&D) in 2022, compared with the $9.4 billion spent by the two Nordic vendors. At the end of 2022, Huawei boasted more than 120,000 "active" patents and claimed this represented "one of the world's largest patent portfolios."
Interdigital, by comparison, spent just $185 million on "research and portfolio development" in 2022, down from $200 million the year before, and held a portfolio in December 2022 of about 28,800 patents. Meanwhile, there is concern about the lack of major US players in mobile standards development. Given the R&D efforts by established companies, Mourad does not expect to see much change in the top ten owners of standard-essential patents with the transition from 5G to 6G, he said this week.
The fear among China's critics is that Huawei may be able to influence the future shape of a global 6G standard to its advantage. There is already talk of Huawei attempting to slow down 6G standardization until China has made further progress on the domestic development of advanced chips needed for 6G products. Opponents might also have jitters about Huawei earning royalties from the rollout of technologies made by western companies. In the technology clash between east and west, a new front could soon open.
