An Israeli technology company seeking patent protection in Germany, France, the United Kingdom and other European markets need not necessarily pursue separate substantive examination in every country. A European patent application before the European Patent Office (EPO) can provide centralized search, examination and grant. The crucial point is what happens after grant: the company must still establish the territorial coverage that serves its business.
There is a distinction between filing a European patent application, receiving a European patent grant and obtaining effective protection in individual countries or through the Unitary Patent system. A patent granted by the EPO does not automatically cover every country in Europe.
The EPO, European Patent Convention and Covered Countries
The European Patent Convention (EPC) governs European patent examination and grant, while the EPO administers the procedure. The EPC extends beyond the European Union. Countries such as the United Kingdom, Switzerland, Norway and Türkiye participate in the EPC system even though they are not EU member states.
As of October 2026, the EPC has 40 contracting states, following Moldova’s accession on June 1, 2026. The territorial effect of a particular earlier application can depend on the dates on which countries joined and the applicant’s procedural choices. Extension and validation agreements can provide access to certain non-EPC territories, but these are distinct procedures and should not be confused with EPC membership.
What Can Be Patented Through the EPO?
An invention must generally be new, involve an inventive step and be susceptible of industrial application. The patent application must describe the invention sufficiently and the claims must be clear and supported by the disclosure. The EPO applies European substantive rules rather than automatically accepting conclusions reached by patent examiners in Israel or the United States.
Europe generally does not provide a broad, one-year inventor-disclosure grace period. Israeli applicants should therefore file before public product announcements, exhibitions, publications or unrestricted disclosure unless a specifically applicable exception has been assessed.
Computer-implemented inventions require careful claim drafting. Mathematical methods and business schemes as such encounter statutory exclusions, but technical computer-implemented solutions are not categorically excluded. The EPO considers the claimed subject matter and its technical contribution under its established examination approach.
Example: An Israeli Water-Filtration Company
Suppose an Israeli manufacturer has developed an industrial filtration unit with a valve arrangement that permits replacement of one filter while water continues flowing through another. It intends to sell the system in Germany, France, the UK and Spain. Instead of starting separate examination in each jurisdiction, the company may consider a European application, provided that its invention meets EPC requirements.
The patent strategy should identify the actual technical contribution: the valve configuration, a locking mechanism, a sequence of operating steps or a particular combination. The claims must be supported by the specification and compared with existing technical publications. This is a hypothetical example rather than a conclusion that the system is patentable.
Three Filing Routes to European Patent Protection
Direct European filing: an application can be filed at the EPO in accordance with EPC rules. If an earlier qualifying application was filed in Israel or elsewhere, it may be possible to claim priority within the applicable 12-month period for the same invention.
Euro-PCT: an international PCT application may be continued into the European regional phase. Filing under the PCT does not itself grant a European patent, and procedural actions must be taken before the EPO to proceed with examination.
National applications: where protection is required in only one or a very small number of countries, direct filings before national patent offices may merit comparison with an EPO route. No single route is always cheaper or legally preferable.
Euro-PCT Entry: The 31-Month Deadline
The ordinary deadline for entry into the European phase is 31 months from the earliest valid priority date or, where no priority is claimed, the international filing date. The applicant must complete the required procedural actions, which may include providing a translation into an EPO official language, paying filing and designation fees and specifying the application documents on which examination is to be based.
Additional fees or steps can apply to examination, supplementary European search and other matters, depending on the case. An Israeli startup should not assume that the European 31-month deadline applies to China, where the ordinary national-phase period differs. The EPO Guidelines for Examination describe the European phase requirements.
Search, Publication and Substantive Examination
The EPO reviews formal requirements, conducts an applicable search and provides an initial opinion on patentability. Publication generally takes place around 18 months after the relevant priority or filing date. The applicant must then ensure that the request for examination and associated fees have been submitted within the deadlines relevant to its filing route.
During substantive examination, an EPO examining division can object to novelty, inventive step, clarity, sufficient disclosure or eligibility. Responses may include technical and legal submissions and allowable claim amendments. Added matter beyond what was originally disclosed is prohibited. The EPO often uses its problem-solution approach in examining inventive step.
If examination is successful, the EPO proceeds through the grant formalities. These can include fees and translations of the claims into the other EPO official languages. The resulting European patent is not the end of the territorial-protection process.
After Grant: National Validation or Unitary Effect
Under the traditional route, an EPO-granted patent takes effect in selected countries following the applicable national validation procedures. Local requirements may involve translations, fees and subsequent renewals. A company should budget for the cost of maintaining rights in the countries it actually needs rather than assuming that grant establishes coverage throughout Europe.
The Unitary Patent route allows a qualifying European patent to have unitary effect across participating EU member states covered at registration. The request for unitary effect generally must be filed within one month from publication of the mention of grant. As of October 2026, unitary effect covers 18 participating states, not every EPC contracting state.
The United Kingdom, Switzerland and Spain are not covered by unitary effect. An Israeli company requiring protection in those territories must evaluate national validation or the other applicable routes. A suitable portfolio may combine unitary effect with conventional validations in countries not covered, without creating overlapping protection for the same territory.
Unified Patent Court and Litigation Strategy
The Unified Patent Court (UPC) has operated since June 2023. It has jurisdiction over specified infringement and revocation disputes involving Unitary Patents and certain traditional European patents in participating states. A centralized procedure may facilitate enforcement in multiple markets but also creates potential exposure to central revocation.
For traditional European patents, an opt-out may be available during the relevant transitional framework, subject to the applicable rules. The opt-out mechanism does not apply to patents with unitary effect. The choice between unitary and classical protection should therefore reflect enforcement and validity risks as well as official fees.
Opposition to a Granted European Patent
The EPC allows a European patent to be opposed before the EPO within nine months of publication of the mention of grant. Opposition is a centralized post-grant procedure and can result in the patent being maintained, amended or revoked. An EPO opposition differs from national infringement proceedings and from UPC litigation.
When considering an acquisition or license of European patents, an Israeli company should review whether opposition or other validity proceedings are pending and how they affect the claimed territorial rights.
European Patent Costs and Representation
Budgeting should include initial searching and drafting, EPO filing and search fees, professional representation, examination, grant costs, possible translations and post-grant validation or unitary maintenance. The cost comparison should consider several years of renewals and enforcement, not simply the filing fee.
Applicants without residence or a place of business in an EPC contracting state generally must be represented by an authorized professional representative for procedural actions before the EPO, subject to limited exceptions. An Israeli company should coordinate with qualified European patent counsel early enough to meet deadlines and align claim strategy across territories.
Choosing the European Route for an Israeli Patent Portfolio
Patent protection should follow the company’s business plan: its principal customers, manufacturing locations, distributors, competitors and likely enforcement venues. If Germany, France and the Netherlands are priorities, the company may compare a Unitary Patent with national validation. If the UK and Spain are also important, additional country-specific planning is necessary.
