1. Donate to a specific object, that is, change the description of the patent right transfer. You just don't charge the other party's fee, but you have to pay the National Bureau for this, and the change fee is 200 yuan.
2. If you donate to the whole society, you have done a procedure of voluntarily giving up the patent right, and you don't have to pay for it.
Do nothing, others use your patent right, you just don't say goodbye to others.
