The previous rules provided an alternative method for correcting errors in provisional applications. Specifically, in § 201.03 section VI the 8th edition (Rev. 9 2012) the MPEP instructed that filing a non-provisional application with inventor overlap would correct any errors as to inventorship in a provisional application. This language, however, is absent in the present edition even though it is based on the same law (35 U.S.C. § 119(e)). I am not sure if this is just a rule that is in practice somewhere or if I am skipping over it, but if it is not in the MPEP I am unable to see why it should not be added.
