When an invention patentee or exclusive licensee seeks the remedies pursuant to the preceding two Paragraphs, he may request for destruction of the infringing products or raw materials or items used in infringing the patent, or request for other necessary disposal.
The right to claim provided in this Article shall become extinguished if not exercised within two (2) years from the time the patentee is aware of the infringement act and the identity of the obligator for the damages, or within ten (10) years from the time of the infringement act.
When the inventor's right to indicate his name is infringed, he may request a ruling to indicate the inventor's name or other necessary measures to recover his reputation.

Article 89
In claiming for damages in accordance with the preceding Article, any of the following options may be adopted to calculate the amount of damages:

1.	To claim in accordance with Article 216 of the Civil Code. A patentee may, however, take the balance derived by subtracting the profit earned through the practice of his patent after the existence of infringement from the profit normally expected through the practice of the same patent as the amount of the damages, provided that no proving method can be presented to justify the damages;
2.	To claim based on the profit earned by the infringer as a result of his infringement act. The entire income derived from the sale of the infringing articles shall be deemed the infringer's profit, provided that the infringer is unable to produce proof to justify his costs or necessary expenses; and
3.	To claim based on the amount to be estimated by the Patent Authority or a professional entrusted by the court.

In addition to the provisions set forth in the preceding Paragraph, the patentee may claim separately for damages at a reasonable amount in case the business reputation of the patentee has been detracted or harmed as a result of the infringement.

Article 90
Any article(s) used in an act of patent infringement or produced by such an act may, upon the application of the injured party to the court, be provisionally seized to serve as the whole or a part of compensation for the damages as may be awarded by judgment.
When the injured party instituted an action claiming for damages under the preceding Article and applying for provisional seizure, the court shall allow procedural relief in accordance with the Code of Civil Procedure. 

Article 91
Where an article which is made by using a patented manufacturing process has never been seen in this country or outside of the country before the filing of a patent application for the said manufacturing process, an article(s) identical thereto made by another person shall be inferred as having been manufactured by using the said manufacturing process.
The presumption made under the preceding Paragraph may be overruled by producing rebuttal evidence. If a defendant has proved that the method used by him in manufacturing the products is different from the defendant has produced rebuttal evidence. The legal right and interests in the manufacturing process and trade secret, as disclosed by the defendant, shall be fully protected.

Article 92
With regard to a litigation involving an invention patent, the court shall send to the Patent Authority one original copy of the judgment rendered by it.

Article 93
The injured party may, after an irrevocable favorable judgment is rendered, request the court to issue a ruling for publishing in a newspaper the judgment in full or in part, at the expenses of the losing party.
