A Phuket beach club owner I know spent three years building a brand — the logo, the name, the reputation on TripAdvisor and Instagram — only to find that someone had registered her brand name as a Thai trademark while her business was growing. The squatter then demanded ฿200,000 to "transfer" the trademark. She ended up paying it, because the legal alternative was worse.
Trademark squatting is genuinely a problem in Phuket's tourism and hospitality sector. So is the more mundane issue of building a brand for years in Thailand without any formal IP protection, then discovering someone else is using the same name in Bangkok. This guide covers what IP protection is available in Thailand, what it actually costs and takes, and what expat business owners in Phuket specifically need to know.

The Four Types of IP Protection in Thailand
1. Trademarks
A trademark (เครื่องหมายการค้า, khrueang mai kan kha) protects your brand identity — the name, logo, slogan, or combination thereof that distinguishes your products or services. In Thailand, trademark protection is registered with the DIP. You register per class of goods or services (using the international Nice Classification). Registration is not automatic — you must apply and be approved. This is the most important IP registration for most Phuket businesses.
2. Copyright
Copyright (ลิขสิทธิ์, lik sit) protects original creative works — writing, photography, artwork, music, film, software code, and architectural designs. In Thailand, copyright attaches automatically at the moment of creation — you don't need to register or file anything. However, voluntary registration (technically "notification") with the DIP creates an official timestamped record of authorship, which is valuable evidence if you ever need to enforce your rights in a Thai court. Cost: ฿300 per work. For content creators, photographers, developers, and designers working in Phuket, copyright notification is cheap insurance.
3. Patents
Patents protect inventions and innovations. Thailand has two relevant categories: full patents (lasting 20 years, for novel inventions with industrial application) and petty patents (8 years, for incremental improvements, lower bar to obtain). Patent filing in Thailand is slow (2–5 years for examination) and expensive relative to the market. Most Phuket-based small businesses won't need patents unless they have genuinely novel product innovations. If relevant, patent filings should be handled by a specialist IP attorney.
4. Trade Secrets
Trade secrets (ความลับทางการค้า) — recipes, formulas, customer lists, business processes — are protected under Thailand's Trade Secret Act B.E. 2545 (2002). Protection is automatic if you take reasonable steps to maintain secrecy. No registration required. For Phuket restaurants with signature recipes or businesses with proprietary processes, include trade secret protection clauses in staff and contractor contracts.

How to Register a Trademark in Thailand: Step by Step
-
Clearance Search
Before filing, search the DIP's trademark database (ipthailand.go.th) for identical or confusingly similar marks in your target classes. This is essential — filing without a clearance search is wasting money if there's a conflicting mark. A Thai IP agent can do a professional clearance search for ฿2,000–5,000, which is worthwhile for anything beyond a basic name check. -
Determine Your Classes
Thailand uses the Nice Classification (45 classes — 34 for goods, 11 for services). Identify which classes cover your business. A Phuket restaurant needs Class 43 (food and beverage services); a clothing brand needs Class 25 (clothing); a software product may need Class 42 (tech services). Filing in too few classes leaves gaps; filing in too many wastes money. An IP agent can advise on the right classes for your specific Phuket business. -
Prepare Application Documents
Required: trademark representation (logo/wordmark in the required format), list of goods/services in Thai, applicant details (name, address, nationality), power of attorney if filing via agent. Documents must be in Thai — one of the key reasons using a Thai IP attorney matters for non-Thai speakers. -
File at the DIP
The Department of Intellectual Property is headquartered in Bangkok (Nonthaburi — near Impact Arena). There is no DIP office in Phuket. Filing can be done in person at the Bangkok DIP, by registered mail, or through the DIP's online portal (ipthailand.go.th/e-filing). A Phuket IP agent will typically handle the Bangkok DIP filing on your behalf. -
Examination and Publication
The DIP examines the application for formal requirements and substantive conflicts. If accepted, it's published in the Thai Intellectual Property Journal for 90 days of opposition. If no opposition is filed, you receive registration. If there are objections or oppositions, you'll need to respond — another reason to have an IP agent. -
Certificate of Registration
Upon grant, you receive a certificate and your trademark is recorded in the Thai trademark register. Your mark is now protected for 10 years from the registration date, renewable indefinitely for further 10-year periods at ฿9,000 per class per renewal.
Trademark Registration Costs: Full Breakdown
| Item | Cost (THB) | Notes |
|---|---|---|
| Clearance search (professional) | ฿2,000–5,000 | Optional but recommended |
| Government filing fee (per class) | ฿1,900 | Nice Classification classes |
| IP agent/attorney fee (basic application) | ฿5,000–15,000 | Per application, regardless of classes |
| Response to DIP objection (if needed) | ฿3,000–8,000 | Not always required |
| Opposition response (if opposed) | ฿8,000–25,000+ | Rare; complex cases higher |
| 10-year renewal (per class) | ฿9,000 | Due before 10-year expiry |
| Typical total (1–2 classes, no complications) | ฿10,000–22,000 | All-in for straightforward registration |
Finding an IP Agent in or Near Phuket
There are no DIP-accredited specialist IP law firms based in Phuket itself — IP law in Thailand is Bangkok-centric. However, several options work well for Phuket-based clients:
- Sunbelt Asia (Phuket office): Offers basic trademark filing as part of their business services portfolio. Not a specialist IP firm, but good for straightforward registrations.
- Phuket Legal (Phuket Town): General commercial law firm with trademark filing services. Can refer to Bangkok IP specialists for complex cases.
- Bangkok IP firms (remote): Many Bangkok-based specialist IP firms (Tilleke & Gibbins, Baker McKenzie Thailand, Rouse, Siam Premier) are accustomed to working with clients outside Bangkok by email/video. For significant IP portfolios, the Bangkok specialist route gives the best quality.
- DIP online filing: For those comfortable filing in Thai, the DIP's e-filing system at ipthailand.go.th allows direct online applications. Only recommended if you or your Thai-speaking partner can navigate Thai government portals confidently.
Phuket's tourism and hospitality sector is particularly exposed to trademark squatting — the practice of registering someone else's established brand name as a trademark to extort payment. If you've built any brand recognition in Phuket (a restaurant name, a villa brand, a product line), file your trademark application as soon as possible. Rights date from the filing date, so early filing is your best protection against squatters.
International Trademark Protection: Madrid System
If you need trademark protection in multiple countries (e.g., you're based in Phuket but also sell in Australia, the UK, or Singapore), Thailand is a member of the Madrid System — the international trademark registration treaty administered by WIPO. This allows you to file one international application that designates multiple countries, administered through WIPO in Geneva. You can file through your home country's trademark office or through the DIP.
For most Phuket businesses operating primarily in Thailand, a domestic Thai trademark is sufficient. International filing makes sense if you have significant operations or IP interests in multiple jurisdictions.

Copyright is more relevant than most Phuket business owners realise. If your business involves any of the following, you have copyright assets worth protecting:
- Website content, product descriptions, blog posts
- Photography (menus, property photos, marketing shots)
- Custom software or apps
- Marketing videos, brand films, Reels/TikToks produced for your business
- Original recipes or method guides (note: recipes themselves aren't copyrightable, but the expression of them in writing or video is)
- Architectural designs for property developments
For most of these, copyright is automatic — you own it without registration. The key issues for Phuket businesses are:
- Contractor vs employee ownership: If a Thai freelancer or agency creates content for you, copyright may rest with them unless your contract explicitly assigns it to you. Always include a copyright assignment clause in any creative services contract.
- Social media platform terms: Using photos or videos you don't own on your Phuket business's social accounts creates liability. Stick to original content, licensed stock, or properly licensed images.
- Enforcement: Copyright infringement in Thailand is both a civil and criminal matter. For serious infringement, DIP has an enforcement division that can act. For online infringement, platform IP complaint mechanisms (Facebook, Instagram, Google) are often faster than legal routes.
