1. In accordance with the requirements of Article 216 of the Civil Code, if no evidentiary methods can be provided to prove the damage, the holder of a plant variety right or his or her exclusive licensee may use the difference between the profits actually made by the right holder after the infringement on the plant variety from profits normally expected from exercise of such variety or its dependent variety.
2. Profits that the infringer actually earned as a result of the infringing activities; where the infringer is unable to produce proof of costs and/or necessary expenses, the entire income derived from the infringer's sales of the infringing articles may be deemed to be the infringer's profits.
In addition to the requirements set forth in the preceding Paragraph, the holder of the plant variety right or his or her exclusive licensee may claim separately for an appropriate amount of remuneration corresponding to losses to his or her respective business reputation as a result of the infringement.
