European patent application

European patent applications and the role of the European Patent Office

The European Patent Office is the central office for processing all European patent applications. It conducts patent searches, examines applications and grants patents.

The European Patent Office conducts a central search and examination for all designated countries. It issues a binding opinion as to whether the subject matter is patentable or not. If the subject matter is found to be patentable, the Office will grant an EP patent (sometimes referred to as an EPO patent).

Europe remains a region of many sovereign states, and once the European Patent Office has done its work, the Applicant must decide in which states the patent will be valid and enforceable. European patent protection will therefore involve a choice of countries to cover.

A complete list of all countries can be found at the end of this text. All major European economies can be named. This includes those that are members of the EU as well as those that are not. Patents in Switzerland, Great Britain or Turkey are often of commercial interest. (Great Britain is and will remain a contracting state of the EPC even after leaving the EU!)

The new European Unitary Patent came into force in 2023 and is now available for use. This allows 17 EU countries to be designated at the same time. In particular, Germany, France and most countries in Central Europe are covered by the EU patent.

If patent protection in three or more member states is of interest, it is almost always worthwhile to file a European patent with the European Patent Office instead of national patents. This is often the case even if only two countries are to be designated.

Question mark-Icon: Who can apply for a European patent?

Who can apply for a European patent?

Any company or individual can apply for a European patent. Those who have neither their domicile nor their principal place of business in a member state of the European Convention must have the assistance of a European patent attorney during the application procedure at the European Patent Office. Since the formulation of a patent application and the correct procedural steps are complicated, this is usually done even by Applicants who are not obliged to do so.

When applying, you must confirm that you are entitled to the invention. For example, an employer can usually apply for patents based on the ideas of its employees. In this case, the European Patent Office needs confirmation that the inventors are employees of the company. In other cases, the rights to the invention may have been transferred to someone else by contract, or the inventor may also be the Applicant, in which case there is nothing to confirm.

Should a European patent be filed earlier or later?

In general, a patent application should be filed as early as possible. It is often the case that a field of development is “hot”, that certain ideas are in the air. An Applicant who files too late will be at a disadvantage compared to earlier applications.

It is usually not necessary for an inventive idea to be perfected and for perfect prototypes to exist. It is not even necessary that a working prototype has been developed. A full understanding of the invention and the ability to describe it theoretically is sufficient. This is another reason why it is usually disadvantageous for the Applicant to wait too long before filing a patent application.

The first application can be filed at the European Patent Office, especially if European or even worldwide protection is desired anyway.

Alternatively, it may be appropriate to file a national application first and then, within twelve months, to file a subsequent application at the European Patent Office for a geographical extension.

In any case, you should avoid disclosing an invention without patent protection. Disclosure can already occur in a conversation with only one person, if that person is not bound by confidentiality obligations, e.g. a confidentiality agreement/NDA. We are happy to advise you on this, as any mistake in this area can have serious consequences.

If you have already filed a national patent application but have missed the one-year period for claiming “priority” of that national application, a European patent application may, under certain circumstances, be filed within 14 months from the date of the first filing. We will advise whether such circumstances apply in this case.

What documents are required for a European patent application?

Only easily obtainable basic information is required: For which individual or company is the application to be filed, who are the inventors? In this context, the addresses are required in each case or perhaps also a contract by which the invention was transferred from the inventor to the Applicant.

If a first national application has already been filed, the filing date and the application number of this application are relevant. In this case, the previous patent application documents (text and drawings) are also required.

Especially if the first application has already been filed, it is therefore possible to prepare a European patent application with little time expenditure. As a rule, we can do this within 24 hours.

If there is no first patent application yet, a main work for the patent attorney is to formulate an appropriate specification of the invention and to file corresponding patent application documents at the European Patent Office. Crucial here are the patent claims, which must be formulated precisely due to a variety of legal considerations. In addition, the concept of the invention is described in detail, perhaps already on the basis of a first prototype. As a rule, drawings are also useful.

What happens to a European patent application at the European Patent Office?

The grant procedure at the European Patent Office is divided into the following steps:

Search

In the first few months after a European patent application is filed, an Examiner at the European Patent Office conducts a search for older inventions or other publications that may be relevant to the invention. These older documents are collectively referred to as “prior art”. In theory, this could be any type of document, but in practice, the search is primarily for older patent documents.

Because a newly filed invention must stand out from what is already known, the older patent documents are important. Firstly, what is claimed in the application must not already exist in a quasi-identical form. This is called the “novelty” requirement. In addition, the development must not be very close to what is already known in a trivial way. This is known as the “sufficient inventive step” criterion. (Don’t be too self-critical about your invention, these are very formal criteria and we will help you to overcome these hurdles with our decades of experience).

Once the search has been completed, the European Patent Office will send you a search report. First, the specific documents are sent. In addition, the documents will be classified as relevant or not relevant. In addition, a more detailed assessment of the filed invention is given, which already resembles a first (perhaps still somewhat superficial) examination report.

Publication

Almost exactly 18 months after the filing date (or, in the case of a national first filing, the priority date), the European Patent Office publishes the patent application. Today, this is only done electronically via the European Patent Office website.

Your invention, as described in the patent application, becomes public knowledge. Although you must provide detailed information about the invention in the description of the patent application, this does not mean that you must disclose all your laboratory secrets. When drafting the application, we will discuss with you what details to include and what not to include.

Publication also has significant advantages for you: Under the law of most Member States, you can claim compensation if someone copies your invention once it is published (not just once the patent is granted!). We are happy to advise you on this as well, if necessary. However, Applicants are always pleasantly surprised to find out that claims for damages are already possible at this early stage, and that the final grant of a patent is not the only relevant factor for such claims.

Examination

A few months after the search report is sent, the examination process begins. Basically, there is a back and forth between the Applicant and the Patent Office, or usually between the Applicant’s patent attorney and a particular Examiner at the Patent Office. It is common that the comments in the search report or even in the first examination report are rather critical. Usually, the Examiner’s objections can be overcome. This is often done by arguments based on the extensive case law of the European Patent Office’s Board of Appeal. Another way to overcome objections is to amend the patent claims somewhat. For example, amended patent claims can be drafted using the subclaims.

Grant

As a rule, the patents we file are granted. So, as a last step in the European patent procedure, the Examiner will inform us in advance in which form a patent can be granted. For this purpose, the texts describing the invention, in particular the patent claims, are resent in their latest version. The patent Applicant must agree to this version of the patent documents and claims. The patent is granted only with this agreement.

It is also at this stage that a decision is made on the countries to be covered. It is also possible to grant a unitary patent valid throughout the EU. An overview can be found here.

What if the EPO rejects my patent application?

If the Examiner is of the opinion that all his objections cannot be overcome, there will be a rejection of the patent application. This usually happens at the end of a lengthy procedure, after the Applicant has had several opportunities to comment.

In any case, the Applicant has the right to request an oral hearing. The case will then be heard not only by one Examiner (the “assigned” Examiner with primary responsibility), but by a three-member Examining Division.

Objections can often be resolved at an oral hearing. Such a hearing can take place online or in person. Since Frankfurt is not far from the main locations of the Patent Office (Munich and The Hague), we are happy to attend oral hearings in person.

An appeal against a possible negative decision can be filed with the Boards of Appeal of the European Patent Office. This leads to a completely new decision on the patentability of the patent application by an independent body.

How much does a European patent application cost?

The fees charged by the European Patent Office are significantly higher than those charged by national patent offices. However, the European Patent Office also covers an economic area of more than 500 million consumers.

The application fee and the search fee are due at the time of filing. The total amount is currently a good € 1,600.00.

The initiation of the examination will cost further fees. The fees due at this stage add up to about € 3,000.00.

For European applications, it should be noted that an annual fee is payable to the European Patent Office from the third year onwards. Currently, the annual fee for the third year is €530.00, the annual fee for the fourth year is €660.00 and the annual fee for the fifth year is €925.00.

We will be happy to advise you regarding your individual application and your desire to cover specific countries in Europe.

How long does it take for a European patent to be granted on the basis of an application?

It usually takes several years from the date of filing to the date of grant, typically four to seven years. Recently, however, the European Patent Office has been granting patents more quickly, and we are pleased to see individual patents being granted even after three or four years.

The speed of grant depends very much on the subject matter of the invention and the workload of the office in that area.

We also like to use the possibility of requesting an accelerated examination. There is a program called “PACE” for this purpose. It is also possible to use the PPH program (“Patent Prosecution Highway”). The accelerated grant of a European patent is particularly possible if a patent has already been granted in another country participating in the PPH program, such as Japan or the USA.

What is an opposition?

Anyone (any natural person, any company) may oppose a patent within nine months after it has been granted. An opposition procedure is then carried out at the European Patent Office.

We have considerable experience in opposition proceedings and assist our clients in defending their granted patents.

We can also assist you in filing an opposition against a patent that interferes with your business interests.

In our view, however, the opposition procedure is generally an advantageous and, by international standards, inexpensive way for all parties to achieve legal clarity and certainty.

Do you have an individual inquiry?

We hope you found this information helpful, but you may have a specific question related to your personal project.
