A regional route for patent protection in Europe through one filing, one examination procedure and a coordinated post-grant validation strategy across selected European states.
The European patent route provides a centralised filing and examination system for obtaining patent protection across multiple European jurisdictions.
A single application is examined by the European Patent Office, replacing separate national prosecution at the early stage. After grant, protection is typically validated and maintained in selected countries depending on the applicant’s strategy.
This route is commonly used where several European markets are commercially relevant and a coordinated regional approach is more efficient than individual national filings.
Legal Nature of the European Patent
The European patent is not a unitary right at the post-grant stage. Once granted, it becomes a bundle of national rights that must be validated and maintained separately in the selected countries.
Unitary Effect After Grant
After grant of a European patent, the patent holder may choose ordinary national validation in individual countries or, where the applicable conditions are met, request unitary effect for the patent.
A European patent with unitary effect, or Unitary Patent, provides uniform patent protection in the participating EU member states without separate national validation in each of those countries.
The European patent route may be relevant where protection is needed across several European Patent Convention member states.
After grant, the European patent usually requires validation and maintenance in selected countries. The validation strategy should therefore be planned with the applicant’s commercial geography in mind.
EPO Member States
Albania, Austria, Belgium, Bulgaria, Switzerland, Cyprus, Czech Republic, Germany, Denmark, Estonia, Spain, Finland, France, United Kingdom, Greece, Croatia, Hungary, Ireland, Iceland, Italy, Liechtenstein, Lithuania, Luxembourg, Latvia, Monaco, Republic of Moldova, Montenegro, North Macedonia, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Sweden, Slovenia, Slovakia, San Marino and Türkiye.
States Participating in the Unitary Patent System
The Unitary Patent does not apply in all European Patent Convention member states, but only in those EU member states that participate in the Unitary Patent system and for which unitary effect already applies.
At this stage, the Unitary Patent covers 18 states: Austria, Belgium, Bulgaria, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Romania, Slovenia and Sweden.
Important: the territorial scope of the Unitary Patent depends on the date of registration of unitary effect and may change as additional states join the system.

The European patent application may be filed through several routes depending on the overall filing strategy.
Direct European Filing
The application may be filed directly with the European Patent Office where Europe is an early strategic priority.
Paris Convention Priority
The European route may be used after an earlier priority filing where protection is later expanded to Europe.
PCT to Europe
The European route is commonly entered from the PCT system as part of an international patent strategy.
Connection with PCT Search and International Examination
The European route fits naturally into PCT strategies and multi-jurisdictional patent strategies.
Under the PCT procedure, the European Patent Office may act as an International Searching Authority (ISA) and International Preliminary Examining Authority (IPEA). If the EPO has prepared the international search report or international preliminary examination report, the relevant materials may be used when entering the European regional phase, and a reduction of the examination fee may apply in certain cases.
Use of PCT Results in PPH Programmes
Under Patent Prosecution Highway (PPH) programmes, the results of PCT international search and international preliminary examination prepared by the EPO may be used to accelerate examination of applications in national phases in a number of jurisdictions, as well as in certain regional procedures.
This approach may be relevant, in particular, for national phases in Australia, Canada, China, Colombia, Israel, Japan, the Republic of Korea, Malaysia, Mexico, Peru, the Philippines, Russia, Singapore and the United States, as well as for the regional phase before the Eurasian Patent Office.
Important: individual PPH routes may be temporarily suspended or resumed depending on the status of the relevant agreements between patent offices. The availability of a specific accelerated examination route should therefore be checked as of the date of the request.
The European patent application includes the standard patent documentation required for examination.
- Applicant details
- Description of the invention
- Claims
- Drawings (where applicable)
- Abstract
- Priority information (if applicable)
- Representative details (where required)
The European patent application proceeds through several stages within the European Patent Office before grant and subsequent national validation.
Filing and Formal Examination
The application is filed and undergoes formal examination. A filing date is established.
Search and Publication
A search is carried out and the application is published together with the search results.
Substantive Examination
The application is examined on the merits to determine whether the invention meets patentability requirements.
Grant and Validation
If the application is allowed, a decision to grant is issued. The patent must then be validated and maintained in the selected European countries.
Important: Grant is only the beginning of territorial protection. Post-grant validation, translations and maintenance must be planned as part of the overall strategy.
Official fees and timelines depend on the filing route, application complexity and post-grant validation strategy.
A detailed breakdown of costs typically includes filing, search, examination, grant, validation and maintenance stages.
A more detailed cost structure may be provided depending on the specific case and jurisdictions involved.
