Alamak. This is serious. Better tell Donald J Trump.
Quora: In their quest to harm China, is Trump now willing to destroy the US military and Federal agencies effectiveness and cause long term paralysis with Sec 889, Sec B of the National Defence Authorization Act?
Masao Miwa replied.
How ironic, Huawei/ZTE have the most patents for 5G so China could deny use of its patents by US companies to develop 5G. As US companies desperately try to stay the ordered ban, their future could be substantially dimmed or ended by denying them access to the China market and use of Chinese patents.

Trump and his sidekick Navarro are on a suicide mission to kill off Huawei at the expense of US companies. The linked article indicates US tech companies are doing their best to fend off the action that could seriously impact their future growth.
“Section 889, part B, of the National Defence Authorisation Act, the law would require companies to certify that their entire global supply chain – not just the part of the business that sells to the US government – is devoid of gear from telecommunications equipment vendors Huawei and ZTE Corp, surveillance systems provider Hangzhou Hikvision Digital Technology and other Chinese surveillance companies.”
Dread over impending anti-Huawei law grows at US companies
One of the key elements to 5G is the use of Gallium Nitride semiconductors, For RF and power applications, GaN is the substrate of choice and Huawei has 2000 patents in this area also. Huawei patents focus on power and RF GaN applications. Not only could Huawei deny patents in this area to US companies, but China produces 95% of GaN wafers for use in circuitry requiring high power and high frequency applications. GaN semiconductors are seeing a rise in applications in phased array radars, missile radars, and space ELINT, key sectors that could suffer similar to threats of rare earth elements. The US military wants the US to have its own rare earth processing facilities in the US and it could, but it will take 3 years and require changes to existing environmental laws to do so if China denies US rare earths from China. The civilian sector for rare earths like electric cars, cannot afford a military price to further erode its competitive stance against the Chinese in the consumer sector. GaN comes mostly from the production of Aluminum, the US may have to support Canada’s aluminum industry to process GaN from its production if denied Chinese sources. Again, it would take investment and effort to do so.
