Patent

“I can’t imagine getting better advocacy or representation in the courts or the Patent Office than what Kim & Chang provides us with. There’s a reason why they’re known as the best.”
– Chambers Asia-Pacific 2018

Overview

Kim & Chang has the largest patent practice in Korea, with more than 260 litigation attorneys, patent attorneys and foreign attorneys, as well as more than 230 patent engineers, specialists and paralegals.

Our size, along with the breadth of work we provide, enables Kim & Chang to have leading experts in all aspects of patent work.

Our attorneys are top graduates of prestigious universities from all over the world. Many have practiced in major law firms abroad, gained significant experience as former judges or Korean Intellectual Property Office (KIPO) examiners, and worked as leading researchers or engineers in various industries. We have some of the most experienced private practitioners in Korea specializing in patent prosecution, IPTAB administrative actions, civil court infringement actions, KTC border enforcements, and IP transactions to assist our clients. Our experience and expertise in the patent field is unmatched.

Diverse technical backgrounds (including advanced degrees and work experience) in the sciences allow Kim & Chang’s patent professionals to fully understand and appreciate a wide range of technological fields and industries. Further, our unique global background enables us to efficiently handle IP matters in Korean, English, German, French, Japanese and Chinese, all within a single office. Many of our clients are non-Korean companies who face the same or related issues in many jurisdictions (e.g., patent litigations in numerous countries involving counterpart patents). These cases demand an additional level of sensitivity, requiring us to pursue the legal claim as aggressively as possible in Korea, while insuring consistency with positions taken in other jurisdictions. We have successfully worked on many such cases, closely coordinating with the client and local counsel in other countries. Further, beyond legal issues specific to Korea, we also have extensive experience in supporting matters outside of Korea, such as U.S. litigations involving the production of Korean language documents or depositions in Korea of witnesses and experts.

The expertise and multinational background of Kim & Chang’s professionals make the firm the recognized leader in providing sophisticated, high-quality legal services for international issues and uniquely qualified to address the legal needs of international companies doing business in South Korea.
