      Remedies for Patent Infringement

      In addition to a patentee, an exclusive licensee can also claim the litigation.

      In addition to a case in which there is a current infringement (direct infringement), it is possible to request prohibition against preliminary infringement (indirect infringement)

      If there is a risk of infringement, prevention of infringement can be claimed.

      Compensation for Damages : Based on an amount of damage of a patentee, an infringer may claim an amount equivalent to the infringer’s profits or royalties that would normally be received. If the infringement is intentional, compensation can be obtained up to three (3) times the calculated amount of damage.
