Patent Translation: Everything you need to know

1 May 2025

Picture this: you have created a unique product and now you need to protect it from imitation. Patents will safeguard your invention, but their protection may not be global.

To protect your invention internationally, you need a translated patent that complies with the legal and technical standards of each jurisdiction. Since every country has its own patent requirements, accurate translation is essential.

But how can you ensure precision while avoiding costly errors that delay your application? That’s exactly what this guide will cover.

What is patent translation?

Why do we need patent translation?

Patent translations are necessary for several reasons, including international patent filings, legal disputes, and market expansion. Businesses seeking to protect their intellectual property across multiple countries must adhere to different language requirements and legal frameworks. 

Without accurate translation, even a well-drafted patent can be misunderstood – leading to delays, rejections, or legal disputes. Precise language ensures your innovation is clearly understood and legally enforceable in each jurisdiction.

International patent frameworks

Securing international patent protection involves several key frameworks and systems, each with its own procedures, filing routes, and translation requirements. Here are some of the most important ones:

• Patent Cooperation Treaty (PCT) The Patent Cooperation Treaty is an international framework that allows applicants to file a single patent application to seek protection in over 150 countries. This simplifies the early stages of filing, but applicants still need to enter the “national phase” in each country later, often requiring translated documents.

• World Intellectual Property Organisation (WIPO) The World Intellectual Property Organisation is the administrator of the PCT system and other international IP treaties. While WIPO facilitates international applications, it does not examine or grant patents itself.

• European Patent Office (EPO) The European Patent Office is a regional authority that grants European patents under the European Patent Convention (EPC). Once granted, patents must either be validated in individual countries (each with their own translation rules) or covered under the Unitary Patent system.

• Unitary Patent A recent option available through the EPO, the Unitary Patent provides uniform protection across participating EU countries. This simplifies post-grant procedures and reduces the need for multiple translations and validations. Understanding these frameworks helps you choose the right patent filing route and ensure compliance with each jurisdiction’s language and technical standards.

Industries that commonly require patent translations

Patent translations are essential across various industries, including:

• Pharmaceuticals & Biotechnology

• Engineering & Manufacturing

• Information Technology

• Automotive & Aerospace

• Medical Devices

• Renewable Energy

Each industry has specialised terminology that requires experienced translators familiar with the field.

What happens if the patent translation isn’t quite right?

Errors in patent translations can have serious consequences, including:

Ensuring high-quality translations mitigates these risks and safeguards intellectual property rights. You can find out more about the consequences of low quality translations in our blog.

Types of patent translations

• Patent Application Translations These translations are required when filing a patent in another country, ensuring compliance with local regulations and linguistic accuracy.

• Patent Litigation Translations During legal disputes, patent-related documents, including prior art references and expert reports, need to be accurately translated for use in court proceedings.

• Patent Validation Translations Once a patent is granted, validation translations may be required to maintain protection in different countries, ensuring compliance with national laws.

Common patent translation mistakes and how to prevent them

Patent documents combine complex technical details with strict legal terminology, requiring translators to be proficient in the technical subject matter while accurately reflecting the legal style required in patent writing to maintain the integrity of the original document.

Some common errors include:

• Mistranslation of key terms: Working with specialised translators prevents incorrect interpretations

• Failure to follow legal formatting: Adhering to jurisdiction-specific patent structures is essential

• Inconsistent terminology: Using industry-specific glossaries ensures uniformity

Why do I need patent translation services?

How much does it cost to translate a patent?

The cost of patent translations varies based on language pairs and document length. Common influencing factors include:

• Volume: The length of the patent affects pricing. To give you an idea, our standard translation service level includes an output of 2,000 words per day by the translator.

• Language Pair: Less common languages may have higher rates due to limited expertise.

• Regulatory Requirements: Some jurisdictions have strict certification needs. Extra charges will apply for translations that require notarisation, sworn certification, or validation by patent offices.
