Article 20 of the Chinese Patent Law stipulates that patent applications must adhere to the principle of good faith. Rule 11 of its Implementation further elaborates that the filing of all types of patent applications must be based on genuine invention and creation activities and prohibits any falsification.

A recent Decision of Reexamination (No. 1878153) highlights the significance of this principle.
