When is an English translation required for a non-English oath or declaration?

An English translation is required for non-English oaths or declarations in most cases. According to MPEP 602.06:

“Unless the text of any oath or declaration in a language other than English is in a form provided by the Patent and Trademark Office or in accordance with PCT Rule 4.17(iv), it must be accompanied by an English translation together with a statement that the translation is accurate.”

However, for oaths or declarations filed under 37 CFR 1.63, there is some flexibility: “the translation may be filed in the Office no later than two months from the date applicant is notified to file the translation.”
