Q5. Filing Application in Foreign Language
 Can we file a patent application in a foreign language?

A5. Yes. You can file a patent application written in English to obtain a filing date. Currently, the Japan Patent Office only accepts English-language applications.
 You must file a Japanese translation of the English-language application within one year and two months from the priority date. Otherwise, the application is deemed to be withdrawn.
 The examination is conducted in the Japanese language.
 You can amend the specification, claims, and drawings within the disclosure of the original English text.  However, you cannot amend the English text in any way.
 If new matter is introduced into the Japanese translation beyond the disclosure of the original English text, it will cause rejection of the application and invalidation of the patent.
