Nexon Korea Corporation has filed a lawsuit against Ironmace Co Ltd, Ju-Hyun Choi, and Terence Seungha Park for misappropriation of trade secrets and copyright infringement. The lawsuit alleges that the individual defendants, who are former employees of Nexon, stole the source code, audiovisual, and other materials developed by Nexon for a video game project called the "P3 Project" and used them to develop a substantially similar video game called "Dark and Darker" through their newly-formed company Ironmace. Nexon claims that it takes reasonable measures to protect its trade secrets, including maintaining written company policies and guidelines, requiring employees to sign an acknowledgement about work-related intellectual property, and requiring employees to sign a data protection agreement. The lawsuit seeks to stop Defendants from continuing to profit from their unlawful actions, including through the distribution of Dark and Darker in the United States and elsewhere. Additionally, Nexon is accusing a former employee named Sangwon Choi of stealing trade secrets and infringing on copyrights by transferring Nexon's P3 Project data and files to his personal servers without authorization, and soliciting members of the P3 Project team to leave Nexon and develop a similar game outside of the company. Nexon is seeking damages and injunctive relief.
