The Strict Stylisation Rule: Why a Cursive Font Won’t Save Your Descriptive Mark in Thailand

Thailand has one of the strictest approaches to trade mark distinctiveness in Southeast Asia. Under Section 7 of the Thai Trademark Act B.E. 2534 (1991), a mark must possess inherent distinctiveness to be registrable — and the Department of Intellectual Property (DIP) applies a particularly demanding standard when descriptive words are involved. A common misconception among international applicants is that applying a decorative font, placing a descriptive word inside a box, or adding a basic border will be enough to make the mark registrable. In Thailand, it is not. Understanding the DIP’s strict stylisation rule — and what truly satisfies it — is essential for any brand entering the Thai market.

The Legal Framework: Section 7 of the Trademark Act

Section 7 of the Thai Trademark Act defines what constitutes a distinctive trade mark. The second paragraph lists the “essential elements” that are deemed inherently distinctive, including invented words, words having no direct reference to the character or quality of the goods, and stylised letters or numerals. Marks that do not possess any of these characteristics fail the distinctiveness test and will be refused.

Critically, Section 7(2)(2) provides that a mark consisting of a word that directly describes the character or quality of the goods or services is not distinctive. This covers laudatory terms (e.g., “Best,” “Premium”), functional descriptions (e.g., “Quick Dry,” “Ultra Clean”), ingredient references (e.g., “Aloe,” “Natural Herb”), and geographic origin indicators. The DIP assesses meaning in both Thai and English, and routinely refuses English descriptive terms that Thai consumers would understand.

Why Minor Stylisation Fails

The DIP’s examination practice is clear: when a mark consists primarily of a descriptive word, simply rendering that word in a distinctive font, cursive script, italic type, or placing it within a basic geometric shape (a box, circle, or banner) does not overcome the descriptiveness objection. The reasoning is fundamental: consumers will still read, pronounce, and understand the descriptive word as the dominant element of the mark. A fancy font does not change the meaning of the word.

The DIP’s position is that when a descriptive word remains the dominant and recognisable element of the mark, the stylisation must be so significant that it effectively overwhelms the word and becomes the primary element consumers perceive. Minor enhancements — such as a script font, a colour gradient, a thin border, or a simple underline — are considered insufficient because the average Thai consumer will still process the mark through its verbal content.

Examples of stylisation that typically fail:

• Descriptive word in a decorative font: Writing “FRESH” in an elaborate script for food products does not remove the descriptive nature of the word.
• Word inside a basic geometric shape: Placing “NATURAL” inside a rectangle, oval, or circle adds no meaningful distinctiveness.
• Colour applied to a descriptive word: Rendering “GREEN CLEAN” in green lettering for cleaning products remains descriptive regardless of the colour treatment.
• Simple borders or underlines: Adding a line beneath or around a descriptive phrase does not transform the mark.

What the DIP Considers Sufficient Stylisation

The DIP’s examination guidelines and practice indicate that acceptable stylisation requires the device or graphic element to dominate the mark. The stylisation must be distinctive in its own right — meaning a consumer would recognise the mark primarily through its visual or graphic character rather than its verbal content. Historically, the DIP has accepted marks featuring:

• Overlapping or interlocking letters: Letters designed to interweave in a complex and visually distinctive pattern.
• Traditional Thai motifs or ornamental patterns: Intricate designs incorporating Thai artistic elements that consumers would perceive as the primary element.
• Elaborate geometric or pictorial devices: Logos where the graphic element is clearly dominant and the descriptive word is subordinate.
• Highly inventive letter arrangements: Characters arranged in an unusual spatial configuration that goes well beyond standard typography.

The key test is whether the visual device element dominates the overall commercial impression. If a consumer looking at the mark would first perceive the descriptive word, the stylisation has failed. If the consumer first perceives the distinctive graphic element and the descriptive word is secondary or subordinate, the mark may be registrable — though with a disclaimer on the descriptive word component.

The 2022 Examination Guidelines: A Partial Liberalisation

In January 2022, the DIP issued updated Trademark Examination Guidelines that brought a degree of liberalisation to the treatment of letter and numeral marks. Following multiple Supreme Court precedents, the new guidelines recognise that combinations of three or more letters, even without stylisation, can be inherently distinctive if they form an uncommon sequence that does not describe the goods or services. This was a significant departure from previous practice, which required visual enhancements for nearly all letter combinations.

However, this liberalisation has limits. Two-letter marks generally still require significant stylisation or must be demonstrated to be distinctive through use. And critically, the relaxation applies to non-descriptive letter combinations — it does not change the rule for descriptive words. A descriptive word remains non-distinctive regardless of how many letters it contains.

The Disclaimer System

Under Section 17 of the Trademark Act, when a mark as a whole is registrable but contains non-distinctive elements (such as descriptive words, common-to-the-trade terms, or non-stylised letters), the DIP Registrar will require the applicant to disclaim exclusive rights to those elements. This means the registration covers the mark as a whole, but the owner cannot claim exclusive rights over the disclaimed descriptive components individually.

The disclaimer system is integral to the Thai registration process. Even when a strong device element carries a descriptive word through to registration, the descriptive word will typically be disclaimed. Brand owners should understand that a disclaimed word offers limited enforcement value when used by competitors.

The Word Mark Challenge in Thailand

A unique feature of Thai practice is that all trade mark applications — including word marks — must be filed as image files, requiring a specific font to be chosen. This means that in practice, word marks in Thailand are treated more like figurative marks: the registration covers the mark in the exact visual form filed, not the word in any font. This has important implications for enforcement and evidence of use, as the mark must be used in a form substantially consistent with the filed specimen.

Strategic Recommendations

• Invest in a distinctive device element: If your brand includes descriptive words, develop a strong, visually dominant logo or graphic device that will carry the mark through registration. The device must be the primary element consumers perceive.
• Do not rely on font or colour alone: A decorative font, colour scheme, or basic geometric border will not overcome a descriptive refusal.
• Accept disclaimers where necessary: If the descriptive word is commercially important, file the mark with a dominant device element and accept the disclaimer on the descriptive component.
• Choose the right filing font: Since word marks are filed as images, select a font that matches your most common commercial use to ensure consistency between the registration and market presence.
• Consider coined alternatives: The most efficient path to registration is an inherently distinctive coined word that avoids descriptiveness entirely.

Common Mistakes

• Assuming a stylish font solves descriptiveness: This is the most common error. The DIP assesses the dominant element; if it remains a descriptive word, the font does not matter.
• Underestimating English-language descriptiveness: The DIP routinely refuses English descriptive terms that Thai consumers understand, particularly in commerce-related contexts.
• Neglecting the device element: Filing a mark where the descriptive word dominates and the graphic element is secondary invites refusal.
• Ignoring the word-as-image filing requirement: All marks are filed as images in Thailand, meaning font choice has lasting consequences for protection scope and enforcement.

Key Takeaway

Thailand’s strict stylisation rule means that minor visual embellishments — decorative fonts, basic borders, colour treatments — will not rescue a descriptive word from refusal under Section 7. The DIP requires the device or graphic element to dominate the mark’s overall commercial impression, relegating the descriptive word to a subordinate, disclaimed component. For international brands, the lesson is clear: invest in a genuinely distinctive visual identity, and treat descriptive words as supporting elements — not the foundation — of your Thai trade mark filing strategy.
