What is cpc certification?

The loss of patent documents proves that this thing has no patent certification, and even the so-called patent is fake. He was afraid of corruption and deleted it directly. It's the same if you ask him to make up a copy. It must be fake. If it passes the patent certification, it will be generously examined by you. How could it be lost? It's not lost, it's deliberately deleted, and your request is meaningless. Conforming to certification and passing certification are still two different things. Yes, it's just that he thinks he's qualified and didn't apply. If you pass the certification, you must have a certificate issued by an authoritative certification body. In this case, he is definitely a liar or has no patent at all!
