The TTAB will honor an extension request to oppose filed in the name of the wrong party if the mistake was to form of the name but not to actual identity of the party.  Opposer’s entity filed an extension request using the wrong name of potential opposer.  TTAB disallowed the opposition.  The Fed Circuit reversed. You can get the name wrong – you just can’t the party wrong.
