Introduction The Lao PDR has overhauled its intellectual property framework with the full implementation of the Amended IP Law (No. 50/NA) in 2024 and 2025. The most critical update for brand owners is the formalization of the Trademark Opposition procedure.

The 60-Day Rule Under the new law, once a trademark is published in the official gazette, third parties have a fixed 60-day window to file an opposition. Previously, the opposition timeline was vague, often leading to uncertainty. Now, the timeline is strict. If you miss this 60-day window, your only option is a costly cancellation action later (which has a 5-year limit).

Bad Faith & 3D Marks The new law also explicitly recognizes “Bad Faith” as a ground for invalidation and expands the definition of trademarks to include 3D marks and animated images, opening the door for non-traditional branding strategies in Vientiane.

How ASEAN IPR Helps: With a strict 60-day clock ticking, you need eyes on the gazette. ASEAN IPR provides a “Lao Trademark Watch” service. We scan every new publication and alert you immediately if a confusingly similar mark appears, drafting and filing the opposition notice before the window closes.
