What is the difference between individual patent transfer and company patent transfer?

This situation has no effect on the assignee. The transferee only cares about the patented technology, and usually doesn't care who the transferor is. So the transferee still has to pay the transfer fee. The only difference in your income should be paying taxes. Of course, the company's patents and transfer income must be turned over to the government in accordance with the tax law, and this can't run away. As for individual patents, if you don't take the initiative to pay taxes, the procedures can be done. If the tax bureau is too busy, it may not take the initiative to collect it. Some people don't understand at all, which is probably the difference.
