COPENHEAVER, BLAINE R is the busiest examiner with 2 pending actions. The examiner handles the entire pending docket, making consistency across responses especially relevant and allowing counsel to develop a focused view of the applicable examination issues.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
