When the patent expires, is selling goods a counterfeit patent? Suspected of false propaganda?

Before the termination of the patent right, the patented product, the product directly obtained according to the patented method or its packaging is marked with a patent mark, and after the termination of the patent right, it is not an act of counterfeiting a patent. If a product that is not known to be a counterfeit patent is sold, and the legal source of the product can be proved, the department in charge of patent affairs shall order it to stop selling, but it shall be exempted from the penalty of fine.
