My concern with this new policy is how will the court system treat "proposed claim amendments?" Will these proposed claim amendments also be viewed under prosecution estoppel? In other words, is this ground that will be deemed as relinquished to the public since the amendments were proposed and subsequently made of record? If so, I fear that interview practice at the USPTO will significantly suffer. It is much more difficult to discuss possible claim amendments with an Examiner if sharing documents in advance creates a record.
Proceed with caution folks - and hope that what I stated above will not be the case.
