A patent gives the owner the right to prohibit/exclude others from using his/her patented technology. It does not even grant the patent owner the right to practice his/her own technology (called 'freedom of operation') because his/her patent may be dominated by another person's or persons' patent(s) that could exclude him or her from doing so.
