invite1.odf failed while applying patch 6678700

Hi,

We are doing the upgrade from 11i to R12.1.3.

Our 11i System has the Brazil localization and we have applied all the pre-requisite patches required for Brazil localization on our 11i system.

However, the upgrade patch 6678700 is failing at invite1.odf with following error:
