One thing is certain: once your patent is authorized, the protection period of the patent starts from the filing date (the time when you file a patent application). From the time you file an application to the time the patent is granted, if someone infringes the patent, you can ask him to stop the infringement and make compensation according to the situation. Since your patent has not been authorized during this period, you can't allow others to exploit the patent just because you don't own it. Of course, if the other party wishes, you can also stipulate this according to the principle of freedom of contract in civil law.
