Utility model and appearance patents are generally around 1 year.
I don't know what kind of patent you are defending. If it is an invention patent, it may take about 1.5 years after the defense.
It is normal to re-examine the patent for utility model after the defense and not receive the information for half a year. Let's wait.
In fact, the time mainly depends on the review progress of patent office examiners. Most of the examiners in the patent office are women, so it is normal that the examination speed is slow.
