What's the difference between transferring unauthorized patents?

Authorized unauthorized patent trading can enable the transferee to obtain a patent certificate and turn the obtained patent into a seemingly self-developed patent, so it has been favored by many enterprises. However, this transaction is also a difficult point in patent transfer. The first is the scarcity of licensed and unlicensed patents. Because the time window of such patents is narrow, about one to two months, combined with the professional scope of customer needs, it is often unable to meet. The second is that there are certain risks. On the one hand, the patent has not really been authorized; On the other hand, it is uncontrollable to complete the change procedures within a limited time after the contract is signed and before the National Information Bureau makes the patent certificate. Sometimes, after the change procedure is submitted, the National Information Bureau has made a patent certificate according to the previous applicant before the change is made, which will lead to the subsequent transaction being unable to be fulfilled.
