Before a person holding a patent on transgenic seed may enter upon any land farmed by another for the purpose of obtaining crop samples to determine whether patent infringement has occurred, the person holding the patent:
The farmer shall grant or deny access within seven days of receipt of request to enter the land. If the farmer withholds written permission, the person holding a patent may petition the circuit court for an order granting permission to enter upon the farmer's land.
