Bring us your invention. We take care of the rest.
Patent attorneys with an engineering background turn your ideas into strong rights in Korea and abroad, and stay with you from filing through disputes and technology transfer.
Lawyers who have seen the end game draft the beginning differently
In Korea a patent takes about two years to grant; an invalidation trial can add two more, and appeals to the Patent Court and Supreme Court can add years beyond that. Having been through every stage, we know how claims must be written from the start. Our managing attorney has led IP firms for over 20 years and handles your matters personally, combining engineering depth with litigation experience.
“Diverse litigation, diverse technologies, diverse foreign matters, diverse technology transfers — that is the foundation of our service.”

FAQ
Frequently asked questions
Can you act as our Korean agent?
Yes. We handle PCT national phase entries, Paris Convention filings and Madrid designations for Korea, and correspond in English.
How long does a Korean patent take?
Grant typically takes around two years from filing, depending on the field and whether expedited examination is used. We will advise on options to speed things up.
Can you reduce our Korean maintenance fees?
Often, yes. Korean annuities grow with the number of claims and the patent's age. We review your portfolio and restructure claims around independent claims where it makes sense.
Can you handle disputes in Korea?
Yes. We handle invalidation and scope‑confirmation trials before the IP Trial and Appeal Board and appeals up to the Supreme Court of Korea.
