When the patent right is transferred, is it necessary to provide the original contract signed by both parties in the list of attachments in the change of specification items? Is it okay to make copies?
Yes, although the contract is the most legally binding and explanatory of all the annexes.
However, the signature (signature) of Party A and Party B appears on the change registration form, and the contract appears as an annex, so the original is not needed, but it must be provided, that is, the original must be reviewed and a copy must be kept.
