In-Depth Guide: Trademark Opposition / Response (Form ก.02) (ก.02)

Trademark Opposition / Response (Form ก.02) is delivered under ILC's Thai Intellectual Property, Trademark and Patent Practice practice, combining MoJ-certified translation, MFA legalization, embassy liaison, and Thai government filing under one project manager. Every case is handled by a NAATI-accredited translator, a Thai Notarial Services Attorney, and a dedicated case coordinator.

Thailand is a Madrid Protocol contracting party (since 2017) and a Patent Cooperation Treaty (PCT) member, making it a strategic Asian filing hub for brand and technology owners. ILC prosecutes trademarks, service marks, collective marks, certification marks, and geographical indications under the Trademark Act B.E. 2534 (as amended 2016), and patents / petty patents / designs under the Patent Act B.E. 2522. Enforcement is delivered through the Central Intellectual Property and International Trade Court (CIPITC), Customs recordal against counterfeit imports, e-Commerce takedown filings, and Suppression Division criminal complaints. Trademark examination timelines shortened to ~18 months in 2024, and DIP now offers e-filing with instant certificates upon grant.

Why choose ILC for Trademark Opposition / Response (Form ก.02)

With more than 15 years of practice, ILC covers every embassy in Bangkok and both MFA offices (Chaengwattana and Chiang Mai). We operate a two-tier QA review and refund the service fee if a document is rejected due to a defect in our translation or certification — government fees and officer discretion excluded.

A working guide to Ip Trademark in Thailand

Ip Trademark is one of the standing service lines that corporate legal departments, embassies, foreign universities, HR compliance teams, and immigration bureaux route their highest-stakes files to. The institutional posture — as opposed to a freelance translator or a generalist firm — is the deliberate reason receiving offices treat the deliverable as finished, not draft. Every Ip Trademark matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.

How the workflow runs end-to-end

For matters that touch multiple counters — Amphur District Office, DBD, DIP, BOI One Stop, or the Criminal Records Division of the Royal Thai Police — a dedicated runner sequences the visits in the correct legal order, so the client is not sent from one office to another chasing missing signatures.

Who this service is for

Foreign missions in Bangkok and international bodies on framework contracts receive a dedicated key-account manager, standardised invoicing on 30-day net terms, and monthly consolidated statements that meet their internal audit format — no bespoke translation project management on their side.

Coverage, fees, and turnaround

Same-day express is offered for filings tied to a flight, hearing, or academic deadline, subject to counter availability at MFA Chaeng Watthana and the destination embassy. The surcharge is quoted before work begins and is not applied retroactively.

Quality assurance and confidentiality

Every certified translation ships with a translator's declaration on our headed paper carrying the linguist's full name, credential number, and dated signature — the format immigration officers, university registrars, and consular staff are trained to accept without follow-up questions.

Start your Ip Trademark matter today

Reach ILC on LINE Official @NAATI, email ilc@thainotary.co.th, or phone 080-5578887. Office hours are Monday to Sunday, 08:30 to 20:00 Bangkok time. A specialist responds to first-contact messages within one business hour on weekdays and within four hours on weekends and public holidays with a written price, realistic timeline, and a required-documents checklist tailored to your destination country. There is no charge for the initial consultation, and no obligation to proceed after receiving the quote — ILCearns repeat business by delivering the first Ip Trademark matter cleanly and on time, not by locking clients into open-ended retainers.
