Patent Translate is available free of charge for users of Espacenet, the European Publication Server and Global Patent Index.



What is Patent Translate?

Patent Translate is a machine translation service for elaborate patent vocabulary and grammar. It is now available in Espacenet and the European publication server. The engine is built on neural machine translation and was trained with millions of patent documents translated by humans.

How was Patent Translate optimised for patents?

In co-operation with the national patent offices in its member states and with other key partner offices, the EPO has provided Google with millions of official, human-translated patent documents. These were used to train the translation engine to handle technical subject-matter and the specific style and format used for patent documents. Every year, millions of documents are added to the EPO's databases. These new documents too are fed into the system, continually improving the engine.

What languages are available?

Patent Translate offers on-the-fly-translation of patent documents for 28 official languages of the EPO's 38 member states, plus Chinese, Japanese, Korean and Russian.

What can I use it for?

The machine translation should give you the gist of any patent or patent-related document, and help you to determine whether it is relevant. You might decide on this basis whether you need to invest in a human translation of the document.

Please note that the engine cannot provide legally binding translations.

Who can see information about requested translations?

We know that confidentiality is crucial for users of information provided by the EPO, so our agreement with Google ensures that nobody has access to information about your searches or translations.
