# PCT international filing and national phase entry

Source: https://luatbanquyen.com/en/services/pct-international-patent-filing · Updated: 2026-08-28

Files one international application to hold your priority date across many countries, then selects the countries and enters the national phase on time.

The PCT grants nothing — it buys time and an international search report before you must pay country by country. The value here is in hitting the deadlines: missing national phase entry loses the right in that country for good.

- **Who may perform this:** Licensed IP representative with a foreign associate network
- **Timeline:** International filing in 1–2 weeks; later milestones run from the priority date
- **How pricing works:** Quoted stage by stage and country by country. WIPO international fees and local counsel fees are separate items, paid against the invoices of those bodies.

## Deliverables

- The international application filed with the appropriate receiving office
- A deadline schedule and a recommendation on which countries to designate
- Coordination of local counsel at national phase entry

## What you provide

- The specification and claim set
- Details of the Vietnamese priority application, if any
- The markets where you actually sell or manufacture
