Welcome to DOOCHANG IP LAW OFFICE.
Since our establishment in 2007 in Gangnam, Seoul, we have been dedicated to providing specialized services in the field of intellectual property (IP) to clients in Korea and across the globe. From the very beginning, our guiding principle has been not merely to secure legal rights, but to support our clients in transforming their creative achievements and ideas into assets of lasting value.
Intellectual property is not simply a legal entitlement; it is a vital strategic resource that strengthens a company’s competitiveness and determines its position in the marketplace. At DOOCHANG IP LAW OFFICE, we recognize this reality and strive to deliver services that go beyond protection—ensuring that inventions, trademarks, and designs are strategically aligned with our clients’ broader business success.
Our patent attorneys and partner lawyers bring together diverse technical backgrounds and extensive industry experience, enabling us to offer comprehensive and systematic legal advice in patents, trademarks, designs, copyrights, and trade secrets.
We hold particular expertise in cutting-edge technologies, biotechnology and pharmaceuticals, IT and software, electronics and mechanics, and brand and design protection. With this depth of knowledge, we assist clients in safeguarding their rights and in building forward-looking IP portfolios to prepare for the future.
DOOCHANG IP LAW OFFICE has accumulated significant experience not only with domestic clients but also with international partners. For foreign companies filing or defending intellectual property in Korea, we provide clear guidance and tailored solutions that help them navigate Korea’s IP system with ease and confidence.
At the same time, for our Korean clients, we actively utilize international systems such as the Patent Cooperation Treaty (PCT), the Madrid Protocol, and the Hague Agreement, to secure global rights efficiently and effectively. Through these efforts, we remain committed to supporting domestic clients in building strong international IP portfolios. By forming a close professional network with us, you will discover valuable synergies that can greatly benefit the handling of mutual client matters.
The value we cherish most is trust. Intellectual property work often involves a client’s core ideas and business strategies, making strict confidentiality and integrity essential. Unlike many other firms, DOOCHANG IP LAW OFFICE owns and operates its own database and servers, allowing us to manage all materials internally without reliance on outsourcing. This structure enables us to maintain the highest level of information security, ensuring that our clients’ valuable data is safeguarded with the utmost rigor.
We also recognize the rapid changes in technology and law, and therefore continually expand our expertise while incorporating the latest developments into our practice. By doing so, we empower our clients to respond proactively to shifting markets and to design strategies for sustainable, long-term success.
Since our foundation in 2007, DOOCHANG IP LAW OFFICE has remained steadfast in our mission to be “a reliable partner in protecting your rights.” We welcome any inquiries relating to patents, trademarks, designs, copyrights, or trade secrets in Korea.
We respect the spirit of innovation, and we are committed to protecting and enhancing the value of your ideas—ultimately helping them grow into globally competitive assets. It is our sincere hope to stand alongside you as a trusted partner in your growth and success.
