Excuse me, what kind of patent counterfeiting will constitute a crime?

Article 84 of the Detailed Rules for the Implementation of the Patent Law stipulates that the following acts are acts of counterfeiting other people's patents:

(a) without permission, mark the patent number of others on the products or product packages manufactured or sold by it;

(two) without permission, using the patent number of others in advertisements or other promotional materials, making people mistake the technology involved for the patented technology of others;

(3) Using someone else's patent number in a contract without permission, causing people to mistake the technology involved in the contract for the patented technology of others;

(4) Forging or altering other people's patent certificates, patent documents or patent application documents.

The above four acts, if the circumstances are serious, can constitute a crime and should be investigated for criminal responsibility.
