Jaewoo Kwak, a partner of Lee & Ko’s Intellectual Property Group, has been selected for the Lexology Index: Client Choice 2026, in recognition of his expertise in the field of intellectual property and his exceptional client service.

Mr. Kwak is widely recognized as a highly versatile practitioner whose comprehensive and profound understanding of both technology and legal principles enables him to excel across a broad range of IP disputes and advisory matters. He achieved a dramatic turnaround and final victory in a decade-long, multi-billion-won patent battle involving ice water purifiers, and played a leading role in securing the Supreme Court decision in the unauthorized BTS photo book case, a landmark ruling that ultimately paved the way for the legislative recognition of the right of publicity in Korea.

He also possesses unparalleled expertise in international patent and trade secret disputes involving advanced technologies, as well as in complex e-discovery matters. More recently, he has garnered additional attention for his extensive work on AI-related and gaming-industry cases.

Since 2005, the Lexology Index: Client Choice has recognized lawyers around the world who demonstrate excellence in client care, based on evaluations from in-house counsel and a rigorous independent review process. Mr. Kwak’s selection reflects the continued trust placed in him by global and domestic clients, as well as his longstanding commitment to delivering the highest caliber of legal service.

Lee & Ko has been honored with two top distinctions at the 2025 Asia IP Awards, held on November 6 in Kuala Lumpur, being named “Korea Copyright Firm of the Year” and “Korea Trademark Litigation Firm of the Year.” These awards recognize the firm’s leadership and excellence across the full spectrum of intellectual property practice.

Lee & Ko’s IP & Technology Group has recently achieved a series of landmark results in high-stakes IP disputes. Most notably, the team secured a decisive victory in the widely publicized “Water Purifier Patent War,” overturning an unfavorable first-instance judgment on behalf of Coway at the appellate level and ultimately prevailing before the Supreme Court. In another precedent-setting matter, the Group successfully established that an online offer for sale of patent-infringing products directed at Korean consumers constitutes patent infringement in Korea, even when the seller’s servers are located overseas. This ruling significantly enhances the substantive protection available to rights holders in an increasingly borderless digital marketplace.

Beyond patents, the Group also advises and litigates across a diverse range of IP fields. It manages complex and high-profile copyright disputes, including prominent mobile-game litigation, and provides robust enforcement and strategic counseling for global and domestic brand owners in trademark matters. Leveraging seamless collaboration between seasoned IP litigators and the patent attorneys of the firm’s affiliated patent practice, Lee & Ko’s IP & Technology Group not only develops effective IP portfolio strategies but also delivers comprehensive ONE-STOP services, ranging from patent, trademark, and design filings for global companies to managing IP litigation and providing counsel on, and resolving, disputes involving cutting-edge technologies and diverse technology-related issues.

The Asia IP Awards honor the best law firms across the region for excellence in trademark, patent, and copyright work. Winners are selected from a shortlist of five firms based on voting by more than 5,000 in-house counsels worldwide.

Lee & Ko has once again reaffirmed its position as Korea’s leading law firm, being recognized as a top-tier firm across all 24 industry sectors and practice areas in Asialaw Profiles 2025. This marks the fifth consecutive year that Lee & Ko has achieved this distinction, an accomplishment unmatched by any other domestic law firm, many of which received top rankings only in select areas.

This recognition reflects Lee & Ko’s breadth of expertise, market-leading capabilities, and client trust across all key areas of legal practice in Korea and the Asia-Pacific region.

In addition, 44 Lee & Ko professionals were honored as Senior Statesman, Elite Practitioner, Distinguished Practitioner, Notable Practitioner, or Rising Star, highlighting the firm’s depth of individual talent and professional excellence.

Vera Eun Woo Lee, a partner of Lee & Ko’s IP Group, has been named one of the “Top 15 Female Lawyers 2025” by Asian Legal Business (ALB) Magazine in its August issue. Among the 15 lawyers selected, she was the sole lawyer from Korea to receive this distinction, a testament to her exceptional expertise and distinguished accomplishments in the IP field.
 
Since joining Lee & Ko in 2004, Ms. Lee has built a distinguished career in IP law, handling the full spectrum of IP matters, including patents, trademarks, copyrights, domain names, unfair competition, IP licensing, and employee inventions. She has also overseen numerous high-profile copyright, trademark, and unfair competition litigations with considerable legal significance. Among her career highlights, Ms. Lee has successfully led complex dispute cases that had no prior legal precedents, namely, a Supreme Court case that served to establish the standards for determining copyright infringement in game works, as well as other landmark cases delineating the scope of protection for photographic works and addressing the long-standing unauthorized use of a mark. 

ALB Magazine is a leading legal magazine in the Asia-Pacific region published by Thomson Reuters, a prestigious legal business publisher. Each year, the magazine recognizes the “Top 15 Female Lawyers” who have demonstrated outstanding achievements throughout their careers, selecting honorees from 13 different Asian countries, including India, Hong Kong, Singapore, Korea, and Japan.
