The online European Patent Register (formerly Register Plus) service is a one-stop shop for all the information available via the European Patent Register and Online Public File Inspection services. It also allows you to access the data in Espacenet and Open Patent Services (patent family information and INPADOC legal status).
The European Patent Register is free of charge.
You can access the European Patent Register in either a secure or non-secure environment. To access the Register in a non-secure environment, just click on the link below. To access the Register in a secure environment, you need to enrol for a username/password.
No. The same data is accessible in both the secure and non-secure environments.
The European Patent Register cannot distinguish between different generations and will call all previous applications "parent application". The more recent application is the parent and the older one the grandparent application, and so on.
You can choose between three kinds of search: Quick Search, Advanced Search and Smart Search. The Advanced Search and Smart Search buttons are displayed on the Quick Search screen.
When you open the European Patent Register, the Quick Search option is displayed by default. You select a category in the drop-down list and enter a search term in the adjacent field. The Quick Search function allows you to find matches for any one of the following terms:
To switch to the Advanced Search option, all you have to do is click the Advanced Search button. Advanced Search allows you to find matches for a combination of terms.
In the drop-down list, select a category and enter a search term in the adjacent field. There are also two other drop-down lists, both preceded by the word AND, with corresponding data entry fields. You can use these to search a maximum of three categories with corresponding search term(s).
Smart Search interprets your search according to whether you enter applicant or inventor names, IPC classes, publication or application numbers, etc. You can find out more about Smart Search and the CQL search language it uses on the Register page.
The European Patent Register allows you to consult published EP, EURO-PCT and PCT files. If it does not display a European/international application, this could be because the application:
Yes, you can use AND, OR and NOT to qualify your search terms in all the available search fields.
Diacritical characters and characters with accents are not supported. For example, to find an applicant called "Hüls", you must enter "Huls". To find an inventor called "Hervé Roussel", you must enter "Roussel Herve".
Using the Register with a username/password means that you can perform searches in a secure environment. The data available in the secure and non-secure environments is exactly the same.
Click "Show history" at the top of the results screen next to the application number and title.
Form 2001A is not used anymore. When it was used, it referred to deficiencies indicated in the European search opinion. It did not have separate annexes indicating those deficiencies.
Not all events trigger a "most recent event". The link below contains a list of those that do. Event codes appear in the Register whenever bibliographic data fields in the EPO's internal system are changed. Events that happen to the file only (e.g. scanning of a document, steps in the appeal procedure that have no effect on data content) and which do not lead to changes in the system do not appear in the Register, and therefore do not generate an event code.
Just enter the publication number in the correct format, e.g. 1 234 567.
All the documents you can view using the Register can be downloaded in a PDF format.
All the bibliographic data from the available panels (About this file, Legal status, etc.) can be downloaded as a single XML file.
The European Patent Register displays this information about 35 months after the filing date of the earliest priority.
Yes. The Date column has arrows next to it which you can click to allow you to sort items in either ascending or descending order.
In either section, simply click on the RSS icon and your web browser will prompt you to subscribe to the news feed. Firefox and Internet Explorer 8.x come with a built-in RSS reader but users of Google Chrome will need to download one. Feedly is a free RSS reader popular with Chrome users.
While looking at an application, you will see Report error in the toolbar. When you click this, a contact form appears with the topic, subject and application number pre-entered for your convenience.
No. The Monitored applications function does not permit duplicates.
The Federated Register is for anyone who has a professional interest in knowing the legal status of one or more EP patents in the national phase, such as patent attorneys, IP consultants or industry representatives.
For each designated contracting state offering this service you will be able to view:
For the moment only the EPC member states will provide data to the Federated Register service.
National patent offices must have a web service set up to send this data to the Federated Register section of the EP Register. Please note that a national office may have an online patent register, but this does not necessarily mean that it can respond to EP Register search queries.
When a country code has an arrow and is underlined, you can click on it to go directly to that country's register:
Please note that links may not be available for each country.
