The transaction history is a great place to get an idea of what is going on with an application, however, it would be awesome to have a real-time status option for where an Amendment or Response is on the Examiner's docket. Similar to the ability to download documents from the IFW in various formats, include an option to view the status of the Amendment or Response. Status could be as simple as:
1) Docketed - Action is on the Examiner's docket
2) Reviewing - Examiner has opened the response and started review
3) Review Complete - Examiner has completed review of the response
4) Action Drafting - Examiner is drafting the next action
These (or similar) brief status descriptions would help practitioners gauge what is going on with their responses to the Office. I think it would be a welcomed addition to Patent Center.
