Are patents filed in 2009 applicable to the patent examination guidelines issued in 2010? There was no guide for this version when I was writing the patent document?

To be precise, patents filed before October 1, 2009 are subject to the old Patent Law and Implementing Rules. Of course, they are also subject to the 2006 version of the Examination Guidelines. Patent applications submitted after October 1, 2009 are subject to the new Patent Law and Patent Law Implementing Rules, and are also subject to the new 2009 version of the Examination Guidelines.
