The invalidity of the contract for the transfer of patent application right means that the contract is of course invalid because of the lack of some effective elements. In judicial practice, once a contract is declared invalid, it will have the legal consequences of being invalid from the beginning. According to Article 58 of the Contract Law, after the contract is invalid or cancelled, the property obtained from the contract shall be returned; If it is impossible or unnecessary to return it, it shall be compensated at a discount. The party at fault shall compensate the other party for the losses suffered as a result. If both parties are at fault, they shall bear their respective responsibilities.
