Why doesn't the United States sanction BOE?

The core technologies of BOE are all independent intellectual property rights. The United States can't do anything about BOE, because the core technology of BOE is independent intellectual property rights, so it won't stop. According to the statistical report on American patent authorization issued by the American patent service organization IFI Claims, in the global ranking of American patent authorization, two China enterprises rank among the top 50: Huawei ranks 20th with 20 17 and BOE ranks 20th with 2 1. BOE is the biggest customer of an American enterprise. If the United States prohibits the American enterprise from supplying products to BOE, the enterprise will go bankrupt.
