Entry into the European Phase of a PCT Application
Bauer IP assists international applicants and foreign patent counsel with Euro-PCT regional phase entry before the European Patent Office, including EPO Form 1200, deadline control, translations, EPO fees, claim amendments and European patent prosecution strategy.
If Europe is a key market for your invention, the transition from the PCT international phase into the European phase should be handled with EPO practice, claim scope, future examination, validation and enforcement in mind.
A Euro-PCT application is an international PCT application that enters the European regional phase before the European Patent Office. After entry into the European phase, the application is handled by the EPO under the European Patent Convention and EPO examination practice.
Key deadline: entry into the European phase must generally be completed within 31 months from the international filing date or, if priority is claimed, from the earliest priority date. Missing this deadline can result in loss of rights unless a legal remedy is available.

What Is Euro-PCT Entry?
“Euro-PCT entry” refers to the procedural steps required for an international PCT application to continue as a European patent application before the European Patent Office. The process is not a single formality. It is a bundle of requirements that must be fulfilled within the applicable deadline.
Once the application has validly entered the European phase, the EPO examines whether the invention meets the requirements for grant of a European patent, including novelty, inventive step, industrial applicability, clarity and sufficient disclosure.
A granted European patent may later be validated in selected EPC contracting states, or the applicant may request unitary effect where available and commercially appropriate.
Main Requirements for Entry into the European Phase
The exact requirements depend on the specific PCT application, language of publication, applicant status, number of claims, fee situation and procedural choices. Typical Euro-PCT entry requirements include the following:
- filing the request for entry into the European phase, usually using EPO Form 1200;
- identifying the international application and applicant correctly;
- appointing a European professional representative where required;
- filing a translation if the international application was not published in English, French or German;
- paying the EPO filing fee and any additional page fees where applicable;
- paying the designation fee;
- paying the examination fee and filing the request for examination;
- paying any claims fees where the number of claims exceeds the applicable threshold;
- paying renewal fees that have become due at the EPO stage;
- reviewing the international search report and written opinion before EPO examination begins;
- filing voluntary amendments if they are strategically useful under EPO practice.
Important: applicants who do not have their residence or principal place of business in an EPC contracting state generally require professional representation before the EPO for European phase proceedings.
Euro-PCT Entry Timeline
| Stage | Typical Timing | Purpose | Attorney Role |
|---|---|---|---|
| PCT filing | International phase | The applicant files one international patent application under the PCT. | Review filing basis, priority claims, disclosure, claims and future European strategy. |
| International search and written opinion | International phase | The international searching authority identifies relevant prior art and gives an initial patentability opinion. | Analyse novelty, inventive step, unity, clarity and possible amendment options. |
| Preparation for European phase entry | Before the 31-month deadline | The applicant decides whether to continue the PCT application before the EPO. | Confirm deadline, fees, representation, translations, claim strategy and procedural choices. |
| Euro-PCT entry before the EPO | Generally by 31 months from filing or earliest priority date | The application enters the European regional phase. | File EPO Form 1200, pay official fees, file translations and submit amendments if appropriate. |
| European examination | After valid entry and EPO processing | The EPO examines the application under EPC standards. | Respond to EPO communications, attend oral proceedings if needed and pursue grant. |
| Grant, validation or unitary effect | After allowance | The European patent is granted and must be brought into force in selected territories. | Advise on validation countries, Unitary Patent request, translations and renewal strategy. |
Claim Strategy Before Euro-PCT Entry
European patent examination can differ significantly from prosecution before other patent offices. Before entering the European phase, it is often valuable to review the claims, description and international search results from an EPO perspective.
In some cases, the best strategy is to enter the European phase with the claims as filed. In other cases, voluntary amendments may help address prior art, clarify technical features, reduce claim fees or align the application with EPO inventive-step practice.
Issues to Review Before Entry
- international search report and written opinion;
- novelty and inventive-step objections;
- clarity and support under EPO practice;
- unity of invention;
- number of claims and possible claims fees;
- technical effect and problem-solution approach;
- basis for amendments in the application as filed.
Possible Strategic Actions
- file voluntary claim amendments on entry;
- reduce or reorganise claim sets;
- prepare arguments for EPO examination;
- protect commercially important embodiments;
- prepare divisional application strategy;
- coordinate with parallel US, CN, JP or KR prosecution;
- plan future validation or Unitary Patent strategy.
Early Processing of a Euro-PCT Application
In some cases, the applicant may wish the EPO to start processing the Euro-PCT application before expiry of the 31-month period. This may be useful where faster European examination is commercially important, for example because of investment, licensing, enforcement planning or competitor activity.
Early processing requires a specific procedural request and compliance with the relevant entry requirements. Whether early processing is suitable should be assessed in view of the international search results, claim strategy, budget and desired prosecution speed.
Practical point: early entry does not automatically mean better protection. It should be used where there is a clear commercial reason to accelerate European prosecution.
Euro-PCT Entry Costs
Euro-PCT costs depend on the size and language of the application, the number of claims, the applicable EPO official fees, attorney work, amendments, translations and later prosecution complexity.
Typical Official Cost Components
- EPO filing fee;
- additional page fees where applicable;
- designation fee;
- examination fee;
- claims fees for excess claims;
- renewal fees due at the EPO stage;
- extension or validation fees where selected and applicable.
Typical Professional Cost Components
- deadline and document review;
- preparation and filing of EPO Form 1200;
- translation coordination;
- claim review and amendment drafting;
- analysis of international search report and written opinion;
- European prosecution strategy;
- later responses to EPO communications.
A reliable Euro-PCT cost estimate should be prepared before the 31-month deadline, especially where the application contains many claims, many pages or complex technical subject matter.

Euro-PCT Entry FAQs
What is a Euro-PCT application?
A Euro-PCT application is an international PCT application that enters the European regional phase before the European Patent Office. After entry, it is prosecuted before the EPO as a European patent application.
What is the deadline for entering the European phase?
The deadline is generally 31 months from the international filing date or, if priority is claimed, from the earliest priority date. The exact deadline should always be checked for the specific application.
Which form is used for Euro-PCT entry?
The request for entry into the European phase is typically made using EPO Form 1200.
Is a translation required?
A translation is required if the international application was not published in one of the official languages of the EPO: English, French or German.
Can claims be amended when entering the European phase?
Yes. Voluntary amendments may be filed where appropriate. Amendments must comply with EPO requirements, including the prohibition on adding subject matter beyond the application as filed.
Can the EPO process a Euro-PCT application before the 31-month deadline?
Yes, early processing may be requested if the applicant wants the EPO to begin processing the application before expiry of the 31-month period and the applicable requirements are fulfilled.
