A Korean patent-law-firm selection should be based on documented staffing, technical capability, translation controls, deadline systems, report quality, fee scope, conflicts, information security, and pilot performance. Comparing these items on the same assumptions produces a reviewable appointment record.

An applicant without a domicile or business address in Korea must appoint a patent administrator with a Korean domicile or business address. Foreign applicants generally appoint a Korean patent attorney. The legal requirement should be distinguished from the separate decision about which firm has the appropriate professionals and operating controls for the portfolio.
| Criterion | Evidence to review |
|---|---|
| Responsible professionals | Named supervising attorney, daily contact, technical reviewer, escalation attorney, and absence coverage |
| Technical capability | Relevant matters handled by the proposed team, technical qualifications, and a sample issue analysis |
| Korean translation | Translator qualifications, attorney review, terminology control, claim and drawing checks, and ambiguity procedure |
| Deadline controls | Docket-entry method, independent verification, non-extendable-date flags, escalation, holiday coverage, and time-zone rules |
| Reporting | Redacted filing and Office Action reports identifying deadlines, issues, recommendations, instructions, and costs |
| Fees | Written inclusions, exclusions, assumptions, official-fee variables, taxes, disbursements, and estimate procedure |
| Conflicts and security | Clearance scope, secure transfer, access controls, retention policy, incident response, and business continuity |
| Portfolio support | Office Actions, interviews, divisionals, appeals, recordals, annuities, transfers, and coordination boundaries |
| Pilot performance | Acknowledgment, issue identification, translation queries, report quality, deadline compliance, and invoice accuracy |
The proposal should identify the Korean patent attorney responsible for the matter and the professionals who will review the claims, specification, drawings, and Office Action responses. A relationship partner's biography does not establish the experience of the person performing the work.
Technical experience should be defined narrowly enough to be evaluated. Semiconductor processing, software architecture, battery materials, mechanical structures, chemistry, and biotechnology require different qualifications. The firm should also identify the escalation contact and the coverage arrangement when the primary attorney is unavailable.
Korean is the prosecution language. A translation error in a technical relationship, claim dependency, transitional term, or reference sign can affect examination and later claim interpretation. The review should determine whether the translation is compared with the claims, drawings, and approved terminology used in related Korean family members.
Shortlisted firms can be given the same representative claim set and asked to describe the translation and review process. The comparison should address preservation of technical and legal meaning, not the style of English correspondence.
The docketing system should distinguish statutory deadlines from periods designated in an official notice and should identify extension availability. The firm should record the official due date and a separate instruction date, independently verify docket entries, flag non-extendable dates, and document escalation when instructions are missing.
Korean public holidays and time-zone differences should be addressed in the service terms. Urgent-filing instructions require a defined receipt time, acceptance confirmation, and authority for extensions or protective action.
A filing report should identify what was filed, the application and priority data, official receipt, fees, and outstanding formalities. An Office Action report should identify the notice date, response deadline, extension position, grounds, available responses, counsel's recommendation and reasoning, requested instruction, and estimated cost where applicable.
Each candidate should price the same representative matter. The proposal should state whether the quoted amount includes Korean translation, attorney review, filing forms, official fees, excess-claim fees, priority work, reporting, docketing, and routine formalities.
The assumptions should address source-language word count, claim count, number of applicants and priorities, drawings, turnaround, and reporting. Office Action billing should identify the charging method and whether an estimate will be submitted before substantive work begins. MOIP's official fee schedule should be used for government charges that vary by claim count or procedure.
A conflict check should cover the applicant, relevant affiliates, known adverse parties, and subject matter where appropriate. The firm should state the information required for clearance and the procedure for urgent preliminary clearance.
Unpublished specifications, inventor data, and client instructions require secure transmission, role-based access, retention rules, incident response, and business-continuity controls. The security review should identify any third-party translation, hosting, or docketing provider that will receive confidential information.
The service description should identify whether the firm handles Office Actions, examiner interviews, divisional applications, appeals, changes of applicant or representative, annuities, and portfolio transfers. Services may be separated, but responsibility and handoff procedures should be defined before the first matter.
A representative pilot matter can test acknowledgment time, issue identification, translation queries, report content, invoice accuracy, and adherence to instructions. The pilot result should be assessed against the proposed service terms before a larger docket is transferred.
The appointment file should retain the candidate team, conflicts result, security review, sample reports, fee assumptions, scorecard, reference or pilot findings, approved exceptions, and final scope. Conditions requiring further review include refusal to identify the responsible professional, an unscoped fee, translation without attorney review, an unexplained deadline-escalation process, or reports that omit the required client decision.
