Are English translations required for foreign priority documents?

English translations of non-English language foreign applications are not always required. However, 37 CFR 1.55(g)(3) specifies three situations where an English translation may be necessary:

“An English language translation of a non-English language foreign application is not required except: (i) When the application is involved in an interference or derivation proceeding; (ii) When necessary to overcome the date of a reference relied upon by the examiner; or (iii) When specifically required by the examiner.”

If a translation is required, it must be filed with a statement certifying that the translation is accurate. This ensures that the USPTO can properly evaluate the priority claim when necessary for examination or proceedings.
