Chapter X: References to Deposited Microorganisms or Other Biological Material

Requirements as to the Language of Sheets Containing References to Deposited Microorganisms or Other Biological Material 

234. Sheets containing references to deposited microorganisms or other biological material must, if they are part of the description, be in the language of filing, or, where a translation of the international application is required under Rules 12.3(a) or 12.4(a), both in the language of filing and the language of the translation. If the receiving Office notices that such sheets are not furnished also in the language of the translation, it promptly invites the applicant (Form PCT/RO/150 or Form PCT/RO/157) to furnish the translation of such sheets.
