First-party answers on Thai trademark filings, invention/petty patents, copyright protection and proceedings before the Central Intellectual Property and International Trade Court — grounded in the Trademark Act B.E. 2534, the Patent Act B.E. 2522 and the Copyright Act B.E. 2537. Fees are quoted per matter by our staff via phone, LINE or email. (18+ search topics covered)
Need your documents reviewed or your case assessed? Ask our team by phone, LINE, or email. We reply during business hours (Mon–Fri 9:00–18:00, Sat 9:00–15:00, ICT).

Trademark, patent, copyright and dispute-related documents used abroad must be translated with consistent technical terminology and certified along the route the receiving authority requires.
Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.
Registration and enforcement are different exercises, and the gap shows sharply once infringement happens.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Register a trademark or patent in Thailand | You need rights enforceable primarily in Thailand | Department of Intellectual Property, Ministry of Commerce | Highly variable by right type and any opposition | Filing in classes that do not cover actual use narrows enforcement more than expected |
| International filing (Madrid or PCT systems) | You want coverage in several countries from one application | Department of Intellectual Property as receiving office, with WIPO | Variable by designated country | Each country still examines under its own law and may refuse individually |
| Infringement action or customs recordation | Infringement appears in the market or counterfeits are being imported | Central Intellectual Property and International Trade Court, and Thai Customs | Highly variable | Weak evidence of use and registration puts you on the back foot from the first hearing |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.

Different claims carry different prescription periods under the Civil and Commercial Code. Knowing when the clock started dictates whether to negotiate, send a demand letter, or file immediately.
One dispute can raise both. They use different courts, procedures and standards of proof; choosing the wrong track wastes time and cost.
Thai courts offer mediation before and during proceedings. A compromise agreement recorded by the court is enforceable and usually far faster than a full trial.
Chats, emails and transfer slips should preserve timestamps and identifiable parties. Foreign-language documents need a Thai translation to be used in court.
Thailand has no common-law notary. Certification is performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand. If your recipient insists on a Notary Public, confirm acceptance in advance.
No lawyer or provider can guarantee a judgment, and advertising guaranteed results conflicts with professional conduct rules. What can be assessed is risk, relevant precedent and settlement options.
Posting party details or allegations while proceedings are live can create separate defamation exposure and damage the underlying case.
Translations used in court or before agencies must be certified by the translator, and in some cases legalised by the Department of Consular Affairs. Machine translations are commonly rejected.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
