Thailand joined the Madrid Protocol in November 2017, giving brand owners a second route into the Thai trademark system alongside the traditional national filing. Nearly a decade in, the data on how each route actually performs tells a fairly specific story.
Two Paths, Same Destination
Both routes end with the same outcome, a Thai trademark registration, but the mechanics and risk profile differ meaningfully.
The Direct National Route
Filing directly with Thailand’s Department of Intellectual Property means engaging a Thai agent from the start, submitting the Kor.01 application form, and working through examination under the standard four-stage process specific to Thailand alone.
The Madrid Route
Filing through the Madrid System lets a brand owner designate Thailand from a single international application managed through WIPO, alongside any other Madrid member country they’re also seeking protection in. As of 2021, more than 32,000 international applications designating Thailand had been filed since the system launched, and by 2018-2019, almost 60% of foreign marks filed in Thailand came through Madrid rather than direct filing.
The Number Worth Knowing Before Choosing
This is where the choice gets more complicated than it first appears.
Statistics gathered during 2017-2018 found that more than 85% of Madrid applications designating Thailand received a provisional refusal, overwhelmingly citing vague or overly broad descriptions of goods and services. Thailand’s DIP doesn’t accept general category headings the way some jurisdictions do, terms like “clothing” or “cosmetics” alone aren’t specific enough, and Madrid applications drafted for multiple jurisdictions at once often use broader language than Thailand’s examiners will accept.
Why the Refusal Rate Doesn’t Necessarily Mean Madrid Is Worse
A provisional refusal isn’t a rejection. It’s a formal objection that can be addressed, but the process for doing so under Madrid carries its own timeline pressure.
| Direct filing | Madrid designation | |
| Local agent needed from day one | Yes | Only if refusal issued |
| Response window if refused | Standard Thai procedure | 90 days to appoint local representative and respond |
| Statutory deadline for Thailand to act | N/A | 18 months to grant or refuse |
| Best suited for | Fewer than 4 target countries | 4+ countries simultaneously |
Once a provisional refusal is issued, the applicant has 90 days to appoint a Thai representative and file a response, a tight window for anyone who filed Madrid precisely to avoid needing local counsel from the outset.
Practical Guidance on Choosing
Industry guidance on this decision tends to converge on a similar rule of thumb: if brand protection is needed in four or more Madrid member countries, the centralized system is usually more cost-effective despite the higher provisional refusal rate in Thailand specifically. For protection in fewer countries, or where Thailand is the primary or sole target, direct filing through a local agent familiar with the DIP’s specific classification requirements tends to avoid the refusal cycle entirely.
Businesses weighing trademark registration thailand options through either route benefit from having the goods and services description reviewed against Thailand’s specific classification standards before filing, regardless of which system is used, since the single biggest source of provisional refusals traces back to language that reads acceptably broad elsewhere but doesn’t clear Thai examination standards.
What Happens After a Certificate Issues Under Madrid
Even after Thailand grants protection through a Madrid designation, there’s an administrative step that took years to fully resolve.
The Local Certificate Delay
Since joining Madrid in 2017, Thailand’s Trademark Office committed to issuing local registration certificates for international registrations designating Thailand, but a technical issue involving provisional refusals on goods and services specifications delayed this significantly. The office only resolved the backlog and began issuing these local certificates in September 2024, working through applications chronologically starting from 2017 and 2018.
Why This Matters for Enforcement
A local certificate carries practical weight in Thailand beyond the WIPO registration record itself, particularly when it comes to enforcement actions, customs recordal, or demonstrating registered rights to local authorities. Brand owners who filed through Madrid years ago and are still waiting on a local certificate for an older application should confirm with their Thai representative where their specific filing sits in that chronological backlog.
Filing Volume Keeps Growing
The trend since 2017 has been consistently upward. International filings designating Thailand climbed from roughly 15,000 by late 2019 to over 32,000 by mid-2021, reflecting growing confidence in the system even with its documented refusal rate. Examiner capacity hasn’t necessarily scaled at the same pace, which is part of why processing timelines and provisional refusal handling remain worth planning around carefully rather than assuming a fast, trouble-free registration regardless of route chosen.
