A Practical Guide for Tech Companies ProtectingTrademarks Across Borders
The Curious Case of “X”—And What It Means for Minimalist Brands
Elon Musk is famously obsessed with the letter “X.” In 2023, he rebranded Twitter as simply “X” and soon after launched his AI company under the name xAI. It sparked headlines—but also raised serious questions among brand owners and trademark professionals:
Can a company really register something as simple as a single letter like “X” as a trademark?
And even if it works in the U.S., what happens in markets like China, India, or Southeast Asia?
This is more than a celebrity quirk. It’s a wake-up call for tech companies with minimalist brand names—from single letters and acronyms to short English words.
Whether you're a software startup using initials, an AI firm with a sleek one-word brand, or a high-tech manufacturer expanding overseas, your trademark strategy needs to work internationally, not just at home.
In this guide, we explore:
- What makes simple trademarks (like “X”, “AI”, or “ZChain”) registrable—or not—in key Asian markets
- Why marks that pass in North America may fail in China, India, or Vietnam
- And how to protect your brand across the global supply chain—before someone else does
Trademark Registrability: Global Principles
Global Principles
Before diving into the specific rules of each country, it’s important to understand the core principles that most trademark offices around the world apply when examining a trademark application:
- Distinctiveness: The more unique a trademark is, the easier it is to register. Coined or arbitrary words (e.g., “Kodak” or “Apple” for software) are usually seen as inherently distinctive. Generic or descriptive terms face significant hurdles.
- Non-descriptiveness: A trademark should not directly describe the product or service. For example, “Fast Car” for a vehicle brand would likely be rejected for lacking distinctiveness.
- Non-confusing: A proposed mark must not be confusingly similar to an existing registered trademark, especially within the same class of goods or services.
- Use or Intent to Use: Some countries (like the U.S.) accept intent-to-use applications, while others (like China) focus on who files first regardless of use. Many jurisdictions also require proof of use within a set timeframe after registration.
Can a Single Letter Like “X” or “A” Be Registered?
In theory, yes—a single English letter can be registered as a trademark. But in practice, most trademark offices view single letters as inherently non-distinctive, especially when presented in plain text.
To improve registrability, applicants often:
- Stylize the letter (e.g., with a custom font or design)
- Combine it with a word or logo
- Show proof of acquired distinctiveness, such as extensive use in the market, advertising reach, or consumer recognition
For example:
- The plain letter “X” is likely to be rejected on its own in many countries.
- But “X” in a bold, futuristic design with long-term commercial use may succeed, especially if the applicant can show consumers associate it with their brand.
The same applies to letters like “A”, which are widely used and more likely to be considered descriptive unless uniquely stylized or paired with additional distinctive elements.
Can “X” Be Registered? A Country-by-Country Snapshot
Let’s take a comparative look at how a single English letter like “X” would fare as a trademark across major jurisdictions in Asia and North America, assuming it is used as a brand name in tech, digital, or consumer sectors.
Takeaway:
Across most of Asia and the Middle East, single English letters are generally considered non-distinctive and difficult to register unless supported by stylization or widespread recognition. North American jurisdictions are more lenient but still require strong visual or commercial distinctiveness. SMEs expanding into these markets should avoid minimalistic marks without a unique visual identity.
Country-by-Country Analysis: What Makes a Trademark Registrable in Asia?
Trademark standards may sound similar across borders, but local laws and examination practices vary significantly. Here's a country-by-country breakdown focused on the key markets that tech, e-commerce, fintech, and manufacturing SMEs are engaging with:
China
Mainland China follows a strict first-to-file system with no requirement for prior use, which makes early filing crucial. The China National Intellectual Property Administration (CNIPA) places strong emphasis on distinctiveness and may reject marks that consist solely of common or non-distinctive elements (like single letters or simple geometric shapes). Marks in foreign languages should also consider registering a Chinese-character version, especially for consumer-facing brands. Trademark squatting is a real risk in China, especially for foreign companies.
Tips:
- Register both English and Chinese versions of your brand.
- File as early as possible.
- Consider stylization to strengthen distinctiveness.
- Keep in mind that China, Hong Kong and Macao are separate jurisdictions for trademark registration.
Hong Kong
Hong Kong operates an independent trademark system, separate from Mainland China. The Intellectual Property Department (IPD) of Hong Kong handles registrations. Applications must be filed directly with the IPD, and protection in Mainland China does not extend to Hong Kong.
Trademarks must be distinctive and capable of distinguishing goods or services. Single-letter marks or commonly used words may be rejected unless presented with a unique design or have acquired distinctiveness through use.
Tips:
- File directly with Hong Kong's IPD.
- Consider stylized or combined marks to increase registrability.
- Local use of the mark can support acquired distinctiveness if needed.
Macao
Macao also has an independent trademark system administered by the Macao Economic and Technological Development Bureau (DSA). Protection in Mainland China or Hong Kong does not cover Macao.
Distinctiveness is required, and marks that are merely descriptive or lack distinct elements are unlikely to be accepted. Local presence is not required, but applicants need to appoint a local agent for filing.
Tips:
- File separately in Macao for local protection.
- Use stylized or graphic elements in the mark if the word or letter is simple.
- Work with a local agent for procedural requirements.
Japan
Japan follows a first-to-file trademark system, administered by the Japan Patent Office (JPO). Trademarks must be distinctive and capable of identifying the goods or services of one company from those of others. While Japan does allow single-letter trademarks, plain letters are generally considered non-distinctive, especially if they resemble commonly used symbols or abbreviations.
Tips:
- Use a stylized design, font, or graphic element to enhance registrability.
- Consider combining the letter with a word or logo if targeting Japan.
- For existing marks with market use, consider submitting proof of acquired distinctiveness through advertising and commercial presence.
South Korea
South Korea’s Intellectual Property Office (KIPO) also enforces a first-to-file system. Similar to Japan, distinctiveness is a key requirement, and single-letter marks in standard font typically face rejection unless supported by unique design or clear secondary meaning. Korean language marks are common, but English-language marks are widely accepted when distinctive.
Tips:
- Avoid submitting single-letter marks in plain type; stylization is critical.
- If the mark has recognition abroad, include documentation of advertising, media coverage, or trade show participation.
- Consider Korean transliterations if consumer-facing or local distribution is involved.
India
India recognizes both use-based and intent-to-use trademark applications. The Indian Trademarks Act, 1999 lays out criteria similar to global norms: a mark must be distinctive and not descriptive or deceptive. However, single-letter or very short marks often face objections unless stylized or proven to have acquired distinctiveness through extensive use. The examination process may involve show-cause hearings if an examiner is unconvinced about registrability.
Tips:
- Use stylization or combine a letter with a device/logo.
- Include supporting materials such as packaging, marketing collateral, and client invoices to demonstrate prior use.
- Be prepared to respond to examination reports and attend hearings if needed.
Taiwan
According to the Taiwan Intellectual Property Office (TIPO), a trademark must be distinctive and capable of identifying goods or services. Single letters like "X" are typically considered non-distinctive unless presented in a stylized form. Taiwan accepts applications in English, but translation or transliteration considerations may still be necessary.
Tips:
- Use stylization, colors, or logos to strengthen registrability.
- Consider registering transliterations if the brand will be marketed in Mandarin.
Vietnam
Vietnam follows a first-to-file system, and registration is handled by the National Office of Intellectual Property (NOIP). Marks must be distinctive, not misleading, and not identical or similar to existing marks.
Tips:
- Avoid simple letters unless stylized.
- Work with a local agent to prepare and submit the required Power of Attorney.
- Consider filing both Latin-character and Vietnamese transliteration versions.
Thailand
Thailand also operates on a first-to-file basis. The Department of Intellectual Property (DIP) requires marks to be capable of distinguishing goods or services. Marks that consist solely of letters, numbers, or descriptive terms are often rejected unless stylized.
Tips:
- Use stylized fonts or include logos to make simple marks distinctive.
- Be ready to include disclaimers for generic elements in your mark.
- Consider Thai transliterations if you plan to reach local consumers.
Malaysia
Malaysia permits registration of both traditional and non-traditional trademarks under the Trademarks Act 2019. Like other jurisdictions, distinctiveness is key.
Tips:
- Register before launching your brand locally.
- Combine text and graphic elements for a stronger application.
- Consider multi-class filing if your product spans several categories.
Indonesia
Indonesia’s Directorate General of Intellectual Property (DGIP) oversees trademark registration. Applications must be in Bahasa Indonesia and distinctiveness is a key factor.
Tips:
- File early; first-to-file is strictly enforced.
- A local agent and a notarized Power of Attorney are required.
- Avoid generic Indonesian terms unless stylized.
Philippines
The Philippines adopts a hybrid system where both intent-to-use and actual use are recognized. The Intellectual Property Office of the Philippines (IPOPHL) allows filing of marks in English, Filipino, or other dialects.
Tips:
- Submit a Declaration of Actual Use (DAU) within 3 years of filing.
- Consider stylization if your mark consists of common words or short terms.
- Multi-class applications are allowed and may streamline your filings.
Laos
Trademark registration in Laos is governed by the Department of Intellectual Property. It is a first-to-file jurisdiction with straightforward procedures.
Tips:
- Use a local agent to navigate filing.
- Stylization increases your chances for approval.
- Consider registering in both English and Lao.
Brunei
Brunei’s Registry of Trademarks operates under the Brunei Trademarks Act, which closely aligns with international standards. Distinctiveness is required, and generic or descriptive marks may be rejected.
Tips:
- Registration is available through the online system.
- Stylized marks or word + logo combinations are more likely to succeed.
- Early filing is essential under the first-to-file regime.
Saudi Arabia
Saudi Arabia is governed by the GCC Trademark Law, administered by the Saudi Authority for Intellectual Property (SAIP). The country adheres to first-to-file rules and requires that trademarks be distinctive, non-descriptive, and not offensive or religiously sensitive.
Tips:
- Avoid religious, political, or culturally sensitive references.
- Arabic translations or transliterations may be required.
- Use logos or graphic elements to strengthen minimalist marks.
- Local legal counsel is highly recommended to navigate formal requirements.
These local differences illustrate why a brand that’s validly registered in Canada or the U.S. may still face hurdles in Asia or the Middle East. SMEs should work with experts who understand the specific laws and filing practices in each market.
United Arab Emirates (UAE)
The UAE operates under the Gulf Cooperation Council (GCC) Trademark Law, but with local implementation by the Ministry of Economy. It is a first-to-file jurisdiction, and marks must be distinctive, not misleading, and not conflict with moral, religious, or public order standards. While the UAE does not explicitly ban single-letter marks, plain marks often fail due to lack of distinctiveness.
Tips:
- Use a stylized or composite mark to improve your chances.
- Avoid cultural or religious sensitivities in letter styling.
- Work with a local agent to navigate Arabic documentation and procedural nuances.
Practical Tips for Tech SMEs Protecting Their Brand in Asia
For North American tech companies entering or collaborating with Asian markets, either working for overseas corporate clients or involved in the global supply chain—whether through outsourcing, licensing, partnerships, or direct market entry—trademark protection should be a priority, not an afterthought, especially when operating in first-to-file jurisdictions.
For e-commerce merchants selling directly to consumers in the global markets, see our earlier blog: How E-Commerce Merchants Should Protect Your Trademark (and Brand) in Foreign Markets (2025 Update).
Some practical steps to be taken to protect the brand identity:
1. File Early—Even Before Market Entry
In countries like China, Vietnam, Indonesia, and Saudi Arabia, trademark rights go to the first applicant, not the first user. Even if you're just outsourcing manufacturing or running a pilot partnership, your brand is at risk of being registered by someone else—whether it's a supplier, competitor, or trademark squatter.
Takeaway: Register before announcing partnerships, launching products, or participating in trade fairs in Asia.
2. Stylize Simple Brand Elements
If your brand name is a single letter, acronym, or common English word, it may be too weak to register on its own in many Asian countries. Stylizing your brand—through a custom font, color scheme, or logo integration—adds distinctiveness.
This is especially important for companies using minimalist branding or tech-oriented names like:
- “X Technologies”
- “A Finance”
- “ZChain”
Takeaway: Treat your visual identity as a legal asset. A good design isn’t just for marketing—it makes your trademark more registrable.
3. Register Local-Language Versions of Your Brand
In Mainland China and other markets, foreign-language marks are often transliterated (or even copied) by third parties. To avoid losing control of your brand's identity:
- Register both your English brand and its Chinese equivalent (either phonetic or semantic).
- Do the same in Indonesia, Vietnam, or Thailand, where local language versions may be favored.
Takeaway: Proactively register translations or transliterations to protect your brand on all fronts.
4. File Across the Supply Chain, Not Just the End Market
If you're outsourcing manufacturing to a jurisdiction (e.g., Vietnam or Thailand) but selling products elsewhere, don't assume you’re safe. Local manufacturers or competitors may try to register your brand in that country—and once registered, they can block exports or claim IP rights.
Takeaway: Don’t just file where your customers are. Also protect your brand in the countries where your partners, vendors, or contract manufacturers are based.
5. Use the Madrid Protocol—But Customize Locally
The Madrid Protocol is an international system that allows businesses to file one centralized application to seek trademark protection in multiple member countries. It’s a convenient way to manage international filings—but it does not guarantee registration in any individual country.
Each jurisdiction still applies its own national laws and examination standards. A trademark accepted in the U.S. may still be rejected in China, India, or Vietnam due to local rules around distinctiveness, prior rights, or language-specific issues.
Takeaway: Use the Madrid Protocol to save time and costs, but don’t rely on it blindly. Always consult with local legal experts—especially in stricter jurisdictions or for minimalist brand names—to tailor your application strategy to local expectations.
6. Set Up Trademark Monitoring and Enforcement Plans
In Asia, even registered trademarks can be challenged, copied, or misused. Many registries don’t automatically alert you to similar new filings. Proactive monitoring helps you:
- Oppose confusingly similar marks
- Track potential infringers
- Maintain exclusivity as your business scales
Takeaway: Work with trusted IP counsel (like those available through Trustiics) to monitor and enforce your rights across jurisdictions.
