To protect distinctive technology and ideas abroad, an overseas patent application is essential — and its success depends on the accuracy of the patent specification translation. This is not mere language conversion but expert work that renders technical terms and legal meaning at once. Apostille Korea handles patent specification translation through certified translation and certification, in one stop.
What is patent translation?
Patent translation is the accurate rendering of a patent specification filed in Korea into the language required by a foreign patent office. A patent is an intellectual property right granted by a state in exchange for the inventor disclosing the technology; to assert that right abroad, you must submit a specification in the relevant country's language.
Claims translation is especially critical. A single word in a claim can narrow or widen the scope of rights, so the work must be done by an expert with both technical-field knowledge and an understanding of patent law — not a mechanical translation. A faulty translation can count against you in a patent-invalidation dispute.

Frequently asked questions
Why does patent translation require an expert?
A single word in a claim can change the scope of rights, so it needs a translator with both technical-field knowledge and patent-law understanding — not a mechanical translation.

Patent specifications (including claims), patent registries, utility-model specifications, and prior-art search documents.
Is certified translation required?
For evidentiary use or certain filings, certified translation is required. We advise per the receiving office.
Do I need an apostille too?
It depends on the destination — apostille for a Hague member, embassy legalization for a non-member. We advise the exact route.
