What are the options for translating foreign language patents at the USPTO?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

The USPTO provides several options for translating foreign language patents. According to MPEP 901.05(d):

• Translations Service Center: The USPTO maintains this center to assist examiners with translations.
• Commercial Services: Examiners can use commercial translation services when necessary.
• Machine Translations: While not always accurate, these can provide a general understanding of the content.
• INPADOC Family Documents: English language equivalents within the same patent family can serve as unofficial translations.

The MPEP advises: “If an English-language equivalent document is not available, the examiner should have the foreign language document translated.” This ensures that examiners have a thorough understanding of potentially relevant prior art.
