First-tier IP Firm in Korea

FirstLaw P.C. is a law firm engaged primarily in the practice of IP law.  FirstLaw P.C. was founded in 1988, and since then has rapidly grown to become one of the leading IP law firms in Korea.  Throughout the span of three decades since its founding, the Firm has consistently enjoyed the reputation for its quality services as a top-tier IP firm in Korea.

FirstLaw’s practice encompasses all aspects of intellectual property, including patents, utility models, trademarks, designs, domain names, trade secrets, licensing, intellectual property portfolio development and management, and other related areas.


Talented and Dedicated Professionals

FirstLaw’s patent attorneys hold advanced degrees in various technical and scientific disciplines, such as computer science, electrical engineering, mechanical engineering, biotechnology and chemistry.  By combining the depth of education and experience with up-to-date knowledge of jurisprudence, rules and procedures of various jurisdictions gained through the Firm’s long-term overseas education programs, FirstLaw’s attorneys provide clients with the most efficient IP prosecution services.


IP Protection Activities

In addition to IP prosecution activities, the Firm specializes in protecting the valuable IP rights of its clients.  FirstLaw’s attorneys formulate comprehensive enforcement programs, which seek to prevent infringement in the marketplace, as well as successfully prosecute and defend infringement actions when they arise.  They also develop domestic and global litigation strategies and coordinate multi-jurisdictional litigation in cooperation with outstanding lawyers in other countries with whom they have established cooperative relationships for many years. 

FirstLaw P.C. has also been actively involved in various IP-related transactions such as mergers, acquisitions, joint ventures, cooperative research and development agreements, consulting and employment agreements, non-disclosure agreements and licenses.
