Patent Europe: How to file a European Patent Application

Patent application in Europe

1. What is a European patent?

A European patent is a right for technical inventions which confers on its proprietor an exclusive right to an invention. Any third party is prohibited to manufacture, to offer, to place on the market, to use or to import the patented subject-matter without the consent of the patent holder.

The term of a European patent is 20 years.

The protective effect of a European patent does not automatically cover all EU member states, but only those states in which the European Patent is validated. This requires payment of fees and filing of translations with the national patent offices. Thus, patent protection in Europe is territorially limited to those EU countries which have been selected. A list of the member states can be found on the EPO website.

2. What can be protected?

Patents in Europe are granted for technical inventions which are new, involve an inventive step and are susceptible of industrial application. Consequently, basically all technical devices and methods may be subject to patent protection, provided that they are of a technical nature.

In contrast to that, the following subject-matter is excluded from protection: Discoveries and scientific theories and mathematical methods; aesthetic creations, schemes, rules and methods for performing mental acts and the mere presentation of information regarding games or business methods, and computer software, provided that the European patent application relates to such subject-matter or activities “as such”.

In the field of computer programs there has developed a special legal practice referring to software patents. According to the latest jurisdiction, the crucial point to decide whether software related subject-matter may be regarded as an invention is the presence of a “further technical effect”. More information about software patents can be found in the menu software patents. You may also contact Mr. Keilitz who is specialized in software patents.

3. How do I apply for a European patent?

A patent application can be submitted at the European Patent Office (EPO). The documents of the patent application must include: A description, patent claims, drawings (optional) and a summary. A patent application can be submitted to the European Patent Office in Munich (EPO). Further information can be found on the website the European Patent Office.

4. What happens after filing?

After filing an EP application, the EPO will search for relevant prior art and issue an extended search report including an opinion on the patentability of the invention. Thereby the EPO examines, if the requirements of novelty and inventive step are met.


An invention is new, if it is not part of the state of the art. The state of the art shall be held to comprise everything made available to the public by means of a written or oral description, by use, or in any other way, before the date of filing of the patent application.

If the subject-matter of the patent was already well-known to the public before the application or priority date, the application is rejected for lack of novelty. Additionally, the content of earlier European patent applications, the dates of filing of which are prior to the filing date of the present patent application and which were published on or after that date, shall be considered as comprised in the state of the art.

Inventive Step

An invention shall be considered as involving an inventive step if, having regard to the state of the art, it is not obvious to a person skilled in the art.

For example, if the claimed subject-matter may be derived from a combination of two prior art documents relating to the technical field of the invention, the EPO will normally assume a lack of inventive step.

In this case it is necessary to limit the scope of the independent claims by incorporating one or more additional technical features. If the claimed subject-matter of the independent claims satisfies the requirements of novelty and an inventive step the EPO will issue a European patent.

Upon receipt of the European search report, the applicant has the possibility to amend the documents of the application. Within 6 months after the publication of the search report the applicant has to file an examination request and pay certain fees.
