Protected works
Literary works (including software), dramatic, artistic, musical, audiovisual, cinematographic, sound recordings, broadcasts and other literary, scientific or artistic works. Ideas and procedures as such are not protected.
Thai copyright arises automatically on creation; no registration is required. DIP copyright notification is only preliminary evidence, not proof of ownership.
Many believe a work must be “registered” to be protected, which is incorrect. This guide prepares creation evidence, assignments and notification for use in disputes.

| Topic | Starting information | Review question |
|---|---|---|
| Applicant and owner | Individual or entity and creators | Ownership and assignments |
| Subject matter | Mark specimen, drawings or specification | Scope of protection and novelty |
| Deadlines | Disclosure and foreign filing dates | Priority, opposition and renewal |

The DIP accepts copyright notifications without verifying ownership. They serve as preliminary evidence, but in a dispute courts still weigh actual creation evidence.
Retain source files, drafts, version history, dates and contributors. For software, keep repository history and developer agreements.
Ownership of commissioned or employee works depends on contracts and law. Put assignments or licences in writing.
Generally the author’s life plus 50 years; some works or corporate authorship run 50 years from creation or first publication.
Thailand is a Berne Convention member, so works are protected in member states without re-registration, though enforcement follows local law.
General preparation guidance. Check current announcements and project facts before filing; eligibility and approval are not assured.
