Trademark & Patent Registration Costs in Thailand
Complete cost breakdown for trademark and patent registration in Thailand — government fees, lawyer fees, and total estimates.
Overview
Intellectual property registration in Thailand is relatively affordable compared to Western countries. Trademark registration through the Department of Intellectual Property (DIP) involves modest government fees, though the process takes 12-18 months. Patent registration is more complex and costly. Engaging a specialized IP lawyer is strongly recommended to navigate the process efficiently.

Money-Saving Tips
File trademark applications yourself through DIP's e-Filing system for simple word marks — government fees are very low.
Register in only the Nice classes you actually need — each class adds THB 1,000.
Bundle trademark and patent work with a single IP firm for package discounts.
Use petty patents (design patents) instead of full invention patents where possible — faster and cheaper.
Copyright registration is optional in Thailand — only register if you anticipate enforcement needs.
All costs are estimates based on 2026 market rates. IP lawyer fees vary significantly based on complexity, number of classes, and whether office actions are required. Government fees are set by DIP and subject to change. Always obtain a written fee estimate before engaging IP services.
