Hwansung Park is renowned as one of the brightest legal analysts in Korea. He is currently serving as the Head of Cross-Border IP Dispute Team and Discovery Team. As a member of the Corporate Practice Group in his earlier years of practice at Lee & Ko, he counseled prominent corporations and entities in a number of M&A deals.
As his practice became more focused on intellectual property and information technology, Mr. Park represented and counseled major IP and IT companies in connection with patents, trademarks, trade secrets, unfair competition, copyrights and domain names. In addition, he was involved in a number of landmark cases, including the first 'functional drawing copyright' lawsuit in the history of Korean jurisprudence. Drawing from his experiences in M&A transactions, he provides strategic advices on intellectual property matters including intellectual property portfolio management, abuse of intellectual property rights issues, establishment and management of non-practicing entity (NPE) and countermeasures against NPEs, intellectual property transactions, and intellectual property financing with keen awareness of his clients' corporate objectives.
Mr. Park is also an expert in IP surveillance and border enforcement with in-depth knowledge of the proceedings before the Korea Trade Commission. He is familiar with the procedures of the Korea Customs Service and has been counseling multinational companies in border enforcements against imitations and counterfeits. Having worked closely with many U.S. law firms, he is also well versed in IP litigation procedures in the U.S., including ITC actions.
Mr. Park is a key member of Lee & Ko's Gaming Practice Group and has a wealth of knowledge and experience on the gaming industry as a whole. He advised Ourpalm in acquiring shares from a major Korean internet company; advised use of service and consumer information agreements for Nextfloor's game software; advised a U.S. gaming company on regulatory issues related to game tournaments; advised Shanda's acquisition of an internet gaming company; and advised game publishing and development agreements for Neowiz and other major gaming companies. Mr. Park also advised gaming clients in numerous intellectual property disputes including patent infringement cases.
