Good to know

When is the deadline?: To claim priority, 12 months from the earliest priority date. Without priority there is no fixed deadline, but file before the invention is disclosed — the grace period for prior disclosure is limited.
Do you need a signed power of attorney before filing?: No. We file on your instructions and send you a power of attorney form to sign afterwards.
Can I file in English?: Yes. A foreign-language application secures the filing date; the Korean translation follows within 1 year 2 months from the priority date (or the filing date).
Who handles my case?: Registered Korean patent attorneys at LNB IP LAW FIRM, Seoul. Questions: lnbip@lnbip.com.
