According to PANews, the Fantom Foundation has been declared victorious in a lawsuit by the Seoul High Court in South Korea. The court recognized that the development of Fantom was led by Andre Cronje. The case originated from allegations made by SikSin, a South Korean food technology start-up, and its CEO Byung-Ik Ahn against the Fantom Foundation. They claimed to have provided technical implementation services for Fantom but accused Fantom of failing to fulfill the service agreement, demanding a claim of over 198 million FTM.

Upon review by the High Court, it was found that SikSin and Ahn failed to design a feasible 'Lachesis Protocol' as per the agreement and were suspected of plagiarizing other technical papers. The court also noted that the application the plaintiffs attempted to develop was contrary to the direction of the Fantom project. The court confirmed that the success of Fantom was due to the internal development team led by Andre Cronje and Quan Nguyen and ruled that the plaintiffs bear all litigation costs.
