How much cost for patent translation in China

The cost for patent translation in China varies based on several factors, including the complexity of the patent, the technical field, and the language pairs involved. Generally, translation costs can range from ¥300 to ¥600 (approximately $40 to $80) per 1,000 Chinese characters, but highly technical patents can be more expensive. Rates may differ if the translation includes detailed claims or diagrams.

Patent translation China certification

In China, when it comes to the translation of foreign patent documents, there are specific notarization and authentication procedures as follows:

1. Notarization by Foreign Notary Institutions

To start with, the patent documents from abroad must be notarized by notary institutions that have the relevant qualifications in the country of origin. The aim of this notarization is to verify the authenticity and legality of these documents, including the genuineness of signatures and seals on them. For instance, in the case of patent documents from the United States, they need to be notarized by local notary public within the US.

2. Authentication by the Foreign Ministry of the Country of Origin

After the notarization process, these documents then have to be sent to the foreign ministry or its authorized departments of the country for authentication. This step is crucial as it validates the authenticity and legality of the notarization actions. For example, for patent documents from the UK, once they are notarized by local notary institutions in the UK, they must be submitted to the UK Foreign Office for authentication.

3. Authentication by Chinese Embassies or Consulates in the Relevant Country

Subsequently, upon completion of the previous two steps, the documents require authentication by Chinese embassies or consulates in the country where the documents come from. The embassies or consulates will re - examine the authentication seals of the foreign ministries on the documents and confirm the overall authenticity of the documents. Only after this process can the patent documents obtain legal validity within China.

It should be noted that the specific notarization and authentication procedures and requirements may vary among different countries. In the event that a country has signed relevant international conventions with China, such as the Hague Apostille Convention, the authentication procedures might be simplified. During the actual implementation, it is advisable to consult relevant institutions in advance regarding the specific procedures and necessary materials to ensure the smooth completion of the notarization and authentication formalities.
