When do patents usually issue authorization notices?

Article 39 of the Patent Law: If the application for a patent for invention is not found to be rejected after substantive examination, the administrative department for patent in the State Council shall make a decision to grant a patent right for invention, issue a patent certificate for invention, and register and announce it at the same time. The examination period of invention patents is generally 2-3 years, and the invention patent rights will take effect from the date of announcement after examination. Article 40 If the application for a patent for utility model or design is not found to be rejected after preliminary examination, the administrative department for patent in the State Council shall make a decision to grant the patent right for utility model or design, issue the corresponding patent certificate, and register and announce it at the same time. The examination period for utility model and design patents is generally 4- 14 months. Upon examination, the patent right for utility model and the patent right for design shall take effect as of the date of announcement.
