What problems should be paid attention to in patent technology transfer?

Many patentees often fail to pay attention to some details when transferring patents, and suffer big losses. So what problems should be paid attention to in patent technology transfer? What problems should be paid attention to in patent technology transfer? The obligee shall not be liable for the invalidation of the patent. Why do you want to add the clause that the right holder does not bear the patent invalidation responsibility? This is because there is a default principle in China's patent law: the patentee should refund the patent transfer fee after the patent is declared invalid. The law is merciless. As we all know, our inventors often have to pay a great price in order to complete the invention and apply for a patent, and the patent transferee should make a good market forecast and technical analysis before buying other people's patents. It stands to reason that the patent assignee should bear part or all of the responsibility. Inventors must pay attention to some patent assignees with bad moral quality, and even if they get the benefits brought by the patent, they will bear the responsibility of declaring the patent invalid. Finally, once again, it is emphasized that when signing a patent transfer contract, the patentee must include a clause that the obligee does not bear the responsibility of declaring the patent invalid. We must not be careless, even if our patent can never be declared invalid, we must plan ahead.
