When a court determines the amount of money to be received for any act prescribed in paragraph (1), item (ii), (a) through (e), and the items of the preceding paragraph, the court may consider the compensation that the person whose business interests have been harmed by the infringement would have received if they had reached an agreement on compensation for the act with the person that engaged in unfair competition, on the premise that unfair competition occurred.
<sup>Ministry of Justice translation — Japanese Law Translation Database System</sup>

**第五項**  第三項の規定は、同項に規定する金額を超える損害の賠償の請求を妨げない。この場合において、その営業上の利益を侵害した者に故意又は重大な過失がなかったときは、裁判所は、損害の賠償の額を定めるについて、これを参酌することができる。

The provisions of paragraph (3) do not preclude a claim for damages exceeding the amount prescribed in that paragraph. In such cases, if the person that committed the infringement that harmed business interests did not do so intentionally or due to gross negligence, the court may consider this in determining the amount of damages.
