Can a provisional application be filed in a language other than English?

Yes, a provisional application can be filed in a language other than English. According to MPEP 201.04:

‘A provisional application may be filed in a language other than English.’

However, it’s important to note that while the USPTO allows this, it may have implications for future patent applications. If you later file a nonprovisional application claiming priority to the provisional, you will need to provide an English translation of the provisional application along with a statement that the translation is accurate. This ensures that the examiner can properly determine if the nonprovisional application is entitled to the benefit of the provisional filing date.
