Please help, can the utility model patent be transferred after application and before authorization? What's the difference between authorization and transfer?

It can be transferred, but because it may not be authorized in the end, the transferee bears certain risks.

What is transferred before authorization is the transfer of patent application right, and what is transferred after authorization is the patent right.

Generally speaking, the price of transferring the right to apply for a patent is lower, because in case it cannot be authorized, the transferee will lose money.
