Baiteng Patent Baba: Is the patent package "over" really reliable?

The patent package is limited to, your patent is special, there are no competing products or no one has applied for it before. If your patent is popular, I believe no one dares to say that it has been packaged with you and needs to sign a contract. Does the other party have any losses? If it has been packaged but can't apply for a full refund, then this promise is dishonest.
