First to File Wins: Why Your SME Clients Should Register Their Trademark Before They Need To

Ask a Thai SME owner who owns their brand name and most will say, without hesitation, that they do. They invented it, they printed it on the packaging, they have traded under it for years, and their customers know it. In ordinary conversation that answer sounds complete. Under Thai trademark law it is not.

Thailand operates a first-to-file system. The party that files for registration first is the one that obtains it, regardless of who began using the mark first. A business that has built real goodwill under a name but never registered it holds a weaker position than it believes, and the weakness only becomes visible at the worst possible moment: when someone else files first.

For a boutique law or accounting firm, this is one of the most useful conversations to have with an established SME client, because the protection is inexpensive relative to what it guards and the risk it removes is both concrete and avoidable.

What First-to-File Actually Means

The rule is simple to state and easy to underestimate. Rights in a registered trademark come from registration, not from use. A business that has traded under a name for ten years but has never filed has no assured right to keep using it if another party registers the same or a confusingly similar mark in the relevant category.

The practical consequences can be severe. A competitor may register the name and demand that the original business stop using it. A former distributor, agent, or overseas partner who knows the brand may register it in their own name. A third party with no connection to the business may file simply to hold the name and sell it back. In each case the original business discovers that the name it considers its own is legally someone else’s, and the cost of recovering it is far higher than the cost of registering it would have been.

This is why trademark advice is best given early and framed plainly. The question is not whether the client has a good brand. It is whether the client has the legal right to keep using it.

Bad-Faith Filing Is a Recognised Problem

World Trademark Review’s 2026 review of Thai trademark prosecution highlights two features of the system that matter to an SME: the registration process is more involved than many applicants expect, and bad-faith filings are a recognised issue that applicants and owners have to navigate.

Bad faith in this context means a filing made not to use the mark but to obtain leverage over someone who does. It can be directed at a domestic business that has not yet registered, or at a foreign brand entering Thailand that has not secured local rights. Challenging such a filing is possible, but it is slower, more expensive, and less certain than having registered first.

For a boutique firm advising a growing client, the point to make is straightforward. Contesting a squatter’s registration is a dispute. Registering early is an administrative step. The cost difference between the two is the argument.

The Basics a Client Should Understand

A firm does not need to turn a client into a trademark specialist, but a few features of the system are worth explaining.

Registration is granted for a category or categories of goods and services, so a mark must be registered in the classes that match what the business actually sells and plans to sell. A name registered for one category does not automatically protect it in another. Thinking about where the business intends to grow, not only where it trades today, is part of choosing the right scope.

The process takes time. Applications go through formal and substantive examination, followed by publication, during which third parties may oppose. In a straightforward case with no objection the process commonly runs for a year or more, and an opposition can extend it considerably. The sensible advice is to file well before the brand is needed in a dispute, because the protection cannot be obtained quickly once a problem has already appeared. The Department of Intellectual Property also operates a fast-track programme for applications that meet its criteria, which can speed the first examination, though it is not a substitute for filing early.

Registration lasts ten years and can be renewed for further periods. Renewal has to be filed within a defined window, and a lapsed registration can leave the brand exposed in exactly the way it was before it was registered. Because ten years is long enough for staff, advisors, and records to change, renewal is the classic deadline that gets missed.

Thinking Beyond Thailand

Thailand is a member of the Madrid Protocol, which has applied since 2017. A business with international ambitions can seek protection in Thailand and other member countries through a single international application filed through its home registry, rather than lodging separate national applications everywhere.

For an SME that exports, sells to tourists, or expects to expand regionally, this changes the planning conversation. The question becomes not only whether the brand is protected at home, but whether it is protected in the markets the business is heading toward. Foreign brands entering Thailand face the mirror-image risk: a local party may register their mark before they do.

Why This Is a Good Conversation for a Boutique Firm

Raising trademark registration is an unusually good advisory move for several reasons.

It is inexpensive for the client relative to the exposure. A modest registration cost removes the possibility of losing the brand outright.

It is easy to start. A single question during an annual review is enough: has the business registered its name and logo, and in which categories?

It strengthens the relationship. A firm that notices an unprotected brand before a dispute arises demonstrates the kind of attention that distinguishes an adviser from a service provider. When the client later needs a contract, a dispute resolved, or a transaction structured, they already have reason to trust the firm’s judgment.

It also connects to the balance sheet. A brand is often one of an SME’s most valuable assets, yet it appears nowhere in the accounts if it was never acquired or capitalised. An accountant who asks whether the client actually owns the legal right to that asset is asking a question that bears directly on the value of the business, and on the succession and credit conversations covered elsewhere in this series.

What a Practical Review Looks Like

A useful client review is short and structured. Identify the names, logos, and slogans the business actually uses. Check which of them are registered, in whose name, and in which categories. Note the registration and renewal dates for anything already protected. Flag the gaps, ranked by commercial importance, and agree which to file first.

Two details are worth checking carefully. The first is the name of the registered owner. A mark registered in a founder’s personal name, or in the name of a former partner or agent, can create a problem when the business is sold, restructured, or passed to the next generation. The second is whether the registration covers the goods and services the business sells today, not only those it sold when the mark was first filed.

A firm should be careful about its own limits. Filing and prosecuting trademarks is specialist work, and a boutique firm without that practice should be willing to refer clients to a qualified intellectual property practitioner while remaining the adviser who noticed the gap and coordinated the response.

FirmFlow and the Long Calendar of a Trademark

Trademark protection is a deadline-driven, document-heavy matter: filing dates, examination correspondence, publication and opposition windows, and renewal dates a decade apart. FirmFlow’s matter record keeps each client’s registrations, correspondence, and renewal dates in one place, so a ten-year renewal does not depend on someone remembering a date from a decade ago.

For the firm, this also turns a one-off conversation into an ongoing relationship. Each client’s brand portfolio sits in the same record as their corporate, tax, and accounting history, which means the next review starts from what is already known rather than from a blank page. The owner who asks whether their brand is safe deserves a clear answer. The firms that ask the question first, before a competitor or squatter does, are the ones whose clients keep the name they built.
