The illegal use of other people's patents belongs to several levels of infringement, Haier.

Level two. The topic comes from Haier's employee code of conduct certification test paper. Illegal use of other people's patents, trademarks, copyrights, trade secrets and other intellectual property rights is a second-class infringement. If the circumstances of patent infringement are serious, the party concerned shall be investigated for criminal responsibility, and if the case constitutes a crime of patent infringement, the sentencing standard shall be fixed-term imprisonment of not more than three years or criminal detention.
