Intellectual Property
Trademarks, copyright, trade secrets and enforcement

IP work covers trademark availability searches and filings, responding to registry objections and oppositions, protecting copyright and trade secrets by contract, licensing and assignment, and taking action against infringement. The firm searches before filing, because a rejected application is slower and costlier to fix than a name changed at the outset.

Pitfalls and common misunderstandings
Rights are territorial
A registration obtained abroad does not by itself protect the mark in Thailand. Filing locally, in the classes matching your actual activity, is what supports enforcement here.
Descriptive marks are hard to register and hard to enforce
Names that merely describe the goods or services often face objections, and even when registered they are weak against similar names. A distinctive element makes both registration and enforcement realistic.
Paying for work is not the same as owning it
Without an assignment or the right contractual wording, copyright in commissioned work may not sit with the business that paid for it. Fixing this after a dispute or an investment round starts is much harder.
Trademark, copyright and trade secret
These protect different things and are obtained in different ways. Most businesses need more than one.
| Point | Trademark | Copyright | Trade secret |
|---|---|---|---|
| What it protects | Names, logos and marks identifying goods or services | Original works such as text, images, code and film | Confidential business information with commercial value |
| How it arises | Registration gives the strongest position | Arises on creation; records help prove it | Kept by confidentiality measures and contracts |
| Duration | Renewable in terms | A long statutory term depending on the work | For as long as secrecy is maintained |
| Key document | Registration certificate | Assignment or work-for-hire wording | NDA plus internal access controls |
| Common pitfall | Filing in the wrong classes | No assignment from freelancers | No access control, so secrecy cannot be shown |
The right combination depends on what your business actually sells and how it is produced.
Hand the whole matter to the firm
The firm can manage the IP portfolio alongside the commercial contracts: searches and filings, the licence or assignment wording, and enforcement where infringement occurs, including certified translations of foreign registrations.
Intellectual Property: frequently asked questions
- Why search before filing a trademark?
- A search shows earlier similar marks in the relevant classes, so you can adjust the mark or the classes before spending on filing, packaging and marketing. It cannot guarantee registration, but it identifies the obstacles that cause most refusals.
- How are classes chosen?
- Classes follow the goods and services you actually offer, and near-term plans can be included. Filing in too few leaves gaps a competitor can occupy; filing in classes you will never use adds cost and can attract objections.
- Does my foreign registration protect me in Thailand?
- Not by itself, because trademark rights are territorial. There are international filing routes that designate Thailand, and there are national filings; which is preferable depends on your existing portfolio and timing.
- Does copyright need to be registered?
- Copyright arises on creation without registration, but recording the work and its ownership makes proof much easier in a dispute. The more important document is usually the assignment or employment wording that puts ownership where it belongs.
- What should a licence agreement cover?
- The scope of rights, territory and term, quality control and approval rights, royalties and reporting, sub-licensing, what happens on termination, and who may enforce against third parties. Ambiguity in scope is the most frequent source of licensing disputes.
- What can be done about counterfeits online?
- Options include platform takedown requests supported by your registration, warning letters, and court proceedings. Preparing the evidence — listings, purchases, comparison of goods — before acting makes each of those routes considerably stronger.
- How long does trademark registration take in Thailand?
- It varies with the registry's workload and with whether an objection or opposition arises. Since the timeline is outside anyone's control, we plan launches so that use of the brand is not entirely dependent on the certificate arriving by a fixed date.
- How do I protect a trade secret in practice?
- Identify the information, restrict access to those who need it, use confidentiality agreements with employees and partners, and keep records of the measures taken. Without demonstrable measures, it becomes difficult to argue the information was secret at all.
