Is it true that BOE’s subsidiary was sued for patent infringement?

It is normal for a company to be sued and to sue others.

For example, in the 2017 "First-instance Administrative Judgment between BOE Technology Group Co., Ltd. and the Patent Reexamination Committee of the State Intellectual Property Office", the plaintiff was BOE, and the defendant was the Patent Office of the State Intellectual Property Office.

In 2015, BOE also sued the Trademark Office.
