HANYANG International Patent And Law Firm

What HANYANG International Patent And Law Firm does

HANYANG International Patent and Law Firm is a Seoul-based intellectual property boutique law firm founded in 1985 by Yeon-Soo Kim and self-described as one of the top 10 IP firms in Korea by filing volume, with offices in the Gangnam district and approximately 100+ professionals across patent attorneys, attorneys, foreign legal counsels, and Chinese patent attorneys. The firm specializes exclusively in intellectual property law, providing domestic and international prosecution of patents, trademarks, copyrights, utility models, and designs, as well as complex litigation and appeals, technology transactions, licensing, counseling, and arbitration across six practice areas: Mechanical/Electrical/Computer Technologies, Bio-Technology & Chemistry, Trademarks & Designs, IP Licensing, Litigation & Dispute Resolution, and Research & Analysis.

The firm's competitive positioning rests on technical depth: many patent attorneys hold undergraduate and advanced degrees in disciplines including electrical engineering, mechanical engineering, genetic engineering, chemistry, biological sciences, and pharmaceuticals, and several partners are former examiners at the Korea Ministry of Intellectual Property (KIPO/MOIP) or have prior in-house experience at companies such as Samsung, IBM Korea, LG Electronics, SK Telecom, Hyundai Motors, and Fujifilm. Internal capabilities are extended through two wholly-owned subsidiaries, TRI (research institute) and UCAN Solution (patent analysis), which provide prior-art searches and analytics using databases such as PATOLIS and Dialog. International filings are supported by foreign legal counsels and a Chinese patent attorney, plus affiliated law firm networks across major industrialized nations.

The business model is quote-based professional services billing across four primary customer segments: enterprise corporations (domestic and multinational), startups and SMEs, individual inventors, and foreign/international clients in markets including the USA, China, and Japan. Marketing is driven by professional networks, industry associations (INTA, AIPPI, MARQUES, ECTA, APAA), an email newsletter on Korean IP law developments, and a multilingual Korean/English/Japanese/Chinese website. The firm is privately held with founder-controlled partnership governance and no disclosed institutional investors, funding rounds, or M&A activity.
