Intellectual Property in Thailand

Thailand has steadily evolved into one of Southeast Asia’s most dynamic hubs for innovation, manufacturing, entertainment, and digital trade. As foreign investment surged, creative industries expanded, and startups grew in record numbers, the country strengthened its intellectual property protections to align with international standards while preserving local enforcement frameworks. The key intellectual property in Thailand encompass statutory rights, administrative registration systems, international treaty obligations, contractual IP mechanisms, and alternative protection doctrines that together form a multi-layered shield for intangible assets.

The main governances of IP law in Thailand are anchored in national legislation regulated by agencies such as the Department of Intellectual Property, specialized courts such as the Central Intellectual Property and International Trade Court, and international conventions coordinated through the World Intellectual Property Organization and the World Trade Organization.

1. Core Categories of IP Rights in Thailand

Thailand adopts the globally recognized pillars of IP, each protected through distinct legal pathways:

a. Trademarks

Trademarks are governed under the Trademark Act B.E. 2534 (1991) and later amendments (notably 2016). Thailand uses a first-to-file registration system, meaning rights belong to the party that registers first, not necessarily first to use. Trademark protection covers:

• Word marks

• Device (logo) marks

• Combined text + logo marks

• 3D marks

• Sound marks

Applications and registrations are handled by the Department of Intellectual Property. Once approved, a Thai trademark is valid for 10 years and can be renewed indefinitely. Foreign entities can own Thai trademarks with no quota limitation. Infringement suits are filed before the Central Intellectual Property and International Trade Court, where preliminary injunctions and seizure orders are commonly used in enforcement.

b. Copyright

Copyright in Thailand is automatic upon creation and does not require registration for protection, under the Copyright Act B.E. 2537 (1994) and amendments in 2015 and 2022. Copyright structures protect:

• Literary works (books, articles, software code)

• Dramatic works

• Musical compositions

• Audio-visual films

• Artistic works and designs

• Architectural plans

• Sound recordings, broadcasts

Although registration is not required, Thailand allows recordation at the Copyright Office for evidentiary benefit. Copyright lasts for the life of the creator + 50 years. Software receives copyright protection but not patent protection unless it presents a technical, non-abstract industrial solution.

c. Patents

The Patent Act B.E. 2522 (1979), amended in 1992 and 1999, governs patents. Thailand provides three types of patent structures:

Pharmaceutical patents, chemical inventions, and biotechnology are patentable in Thailand—though enforcement timelines and regulatory exceptions (e.g., compulsory licenses) apply under WTO TRIPS obligations.

2. Specialized and Alternative IP Protection Structures

Thailand also uses secondary IP doctrines to protect assets that fall outside mainstream categories:

a. Trade Secrets

Trade secrets are protected under the Trade Secrets Act B.E. 2545 (2002)—no registration required. To qualify, the information must:

• Not be publicly known

• Have commercial value derived from secrecy

• Be protected through reasonable confidentiality measures

Companies commonly secure trade secrets through:

• Internal data access controls

• NDAs (non-disclosure agreements)

• Employee confidentiality clauses

• Vendor secrecy provisions

Misappropriation allows civil damages, injunctions, and criminal penalties.

b. Geographical Indications (GIs)

GIs are protected under the Protection of Geographical Indications Act B.E. 2546 (2003). This structure protects regional products such as Thai silk, coffee, wine, fruit, and artisan goods whose quality or reputation is linked to a specific origin. GI registration is also administered by the Department of Intellectual Property. Unlike trademarks, GI rights often belong to community groups or producer collectives, not individual applicants.

c. Plant Variety Protection

New plant breeds are protected under the Plant Varieties Protection Act B.E. 2542 (1999), which complies with UPOV-style standards but allows Thai-specific biodiversity and benefit-sharing conditions. This structure is relevant to agricultural innovation and biotech investors.

d. Integrated Circuit Layout Designs

Layout designs of semiconductor chips are protected under the Protection of Integrated Circuit Layout-Designs Act B.E. 2543 (2000). Registration is required and grants 10-year protection. Thailand remains one of the few ASEAN countries with stand-alone statutory IC protection.

3. International Treaty-Based IP Structures Applicable to Thailand

Thailand layers its national IP system with global treaties:

• TRIPS Agreement under the WTO

• Paris Convention for industrial property

• Berne Convention for copyright

• Madrid Protocol for international trademark filing

• Patent Cooperation Treaty (PCT) for international patent entry

• WIPO Performances and Phonograms Treaty (WPPT) for music and broadcasts

Through these treaties, foreign applicants may enter Thailand through PCT national phase, register Thai trademarks using the Madrid system, and enforce copyright protections for foreign works under Berne reciprocity.

4. Contractual IP Structures (Non-Statutory Enforcement Tools)

Statutory rights are only the first layer. Thailand relies heavily on contract-based IP structuring, which determines ownership allocation, commercial licensing, royalties, confidentiality, and asset succession. These include:

a. IP Assignment Agreements

Used to transfer ownership of trademarks, patents, or copyright from creator to business entity. Common assignment structures include:

• Founder → startup company

• Designer → manufacturing IP owner

• Freelancer → hiring client

Assignments should be registered with the Department of Intellectual Property (where applicable) to be enforceable against third parties.

b. Licensing Agreements

Licenses allow use without ownership transfer. Licensing structures in Thailand include:

• Exclusive licenses → only one party may use

• Non-exclusive licenses → multiple parties may use

• Sublicensing rights → allowed if written into contract

Copyright licenses do not require recordation, but trademarks and patents can be recorded at the Thai Land Office / DIP for legal enforceability and customs monitoring.

c. Franchise IP Structuring

Franchise contracts commonly bundle trademarks, copyright material (manuals, signage, recipes, packaging), and confidential know-how under structured royalty formulas. Thailand does not have a stand-alone franchise law, but franchises are enforceable under contract law + trademark protections.

d. NDA and Confidentiality Clusters

NDAs are widely used to structure non-patent protections—especially for startups, prototypes, algorithms, medical formulas, customer databases, distribution pipelines, and manufacturing processes.

e. IP Joint Ownership Agreements

When multiple creators or companies co-develop an asset, joint IP structures define:

• Percentage ownership

• Management rights

• Licensing revenue allocation

• Enforcement rights (who can sue)

• Exit mechanisms

Thailand allows joint ownership but requires written agreements or disputes default to shared rights, which can complicate commercialization.

5. Customs Monitoring and Border Protection Structures

Trademark and copyright recordation can also be filed with the Thai Customs Recordation System under the Thai Customs Department. Once recorded, customs officers may:

• Monitor import/export shipments

• Detain counterfeit goods at borders

• Notify IP owners for verification

• Support destruction or prosecution proceedings

This is critical for brand owners relying on manufacturing exports.

6. IP Enforcement Structures in Thai Litigation

Thailand uses parallel enforcement pathways:

Civil Litigation

• Damages based on actual + punitive loss (for some rights)

• Temporary and permanent injunctions

• Search and seizure orders

• Asset freezing (rare, strategic cases)

Handled by the Central Intellectual Property and International Trade Court.

Criminal Actions

• Police raids authorised by the Royal Thai Police

• Product confiscation

• Criminal fines and imprisonment for commercial counterfeiting

• Public prosecutor action handled by the Office of the Attorney General

Many brand owners pursue criminal raids for rapid disruption, then follow with civil damages.

Administrative Complaints

Filed before the Department of Intellectual Property for opposition, cancellation, or invalidation proceedings without entering court.

7. Risks in Structuring IP Rights in Thailand

The biggest structural risk is failing to turn automatic rights (such as copyright and secrets) into contractually provable ownership clusters.

8. Strategic IP Structuring Recommendations

For buyers, creators, and investors in Thailand:

✅ Register trademarks early via DIP or Madrid entry
✅ Use assignment agreements for copyright transfers
✅ Patent locally drafted innovations for Thai market
✅ Combine statutory rights with contract-driven ownership
✅ Record eligible marks with customs for border monitoring
✅ Use NDAs and access-control logs for trade secret qualification
✅ Use civil + criminal parallel enforcement when commercially beneficial

Conclusion

Thailand provides a sophisticated multi-dimensional structure for protecting intellectual assets. While trademark and patent protections rely on registration, copyright and secrets are automatic—but benefit strongly from recordation and contractual assignment. International treaties extend protection for foreign IP into Thailand, but enforceability is maximized when statutory rights are integrated with local agreements, court systems, and customs monitoring.
