Incorrect Translation of the International Application

If, because of an incorrect translation of the international application, the scope of any patent granted on that application exceeds the scope of the international application in its original language, the competent authorities of the Contracting State concerned may accordingly and retroactively limit the scope of the patent, and declare it null and void to the extent that its scope has exceeded the scope of the international application in its original language.
