    Why Choose Us  
In-house Translators

Sunyu employs over 400 translators and several patent agents, of whom more than 70% have earned a Master's degree or above. Most of our translators have already acquired solid technical backgrounds and extensive field experience before joining Sunyu.

Practical Experience

Sunyu has engaged in patent-related services for over ten years. In particular, we specialize in the multilingual translation of PCT documents. On average, we are able to handle the translation of over 10,000 PCT and OA cases every year. Over the years, we have translated more than 1.2 billion words.

Strict Confidentiality

Sunyu adheres to strict confidentiality policies and is committed to achieving complete document security.

Advanced Technical Support

Sunyu has developed its own information management system, computer-assisted translation (CAT) software, and a patent database to facilitate interaction between departments, improve the productivity of existing office procedures, and guarantee the confidentiality of all information that we receive from our clients.

Translation SOP

At Sunyu, quality control (QC) is an important aspect of the entire work process. We have established a clear and systematic set of standard operating procedures (SOPs) to ensure the successful implementation of our QC procedures.
