<The Appeal Brief must be filed within 2 months of that filing.>
Are you sure an appeal brief is required for the 584. As I understand it, there are two different kinds of appeals. One is where you are appealing one or more errors made by the examiner. The other is a non-appealable appeal. Essentially covering all other situations. From the wording of the appeal notice, it sounded like this was one of those non-appealable appeals, because it was just to keep the clock ticking for the examiner to act. Yes?
