The National Research Council of Canada has 26 pending office actions within the Chemistry & Materials technology area. This workload is spread across 25 distinct examiners, showing that almost every pending action is assigned to a different individual. The portfolio is highly dispersed administratively, spanning 22 distinct art units at the USPTO.
JOHNSTON, BRIEANN R is the busiest examiner for the council, currently overseeing 2 pending office actions. Since there are 26 pending office actions and 25 distinct examiners, the level of examiner concentration is low. The involvement of 22 distinct art units suggests a very broad technical scope within the Chemistry & Materials field, requiring specialized knowledge across many different examination groups. This administrative dispersion means that practitioners will interact with a wide variety of USPTO personnel to resolve the 2 pending office actions assigned to the busiest examiner.
Based on the USPTO statutory response window for each pending office action. 12 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 12 of the docket's apps have a known mailing date.
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.
| Bucket | Cases |
|---|---|
| §103 only | 10 (37%) |
| §112 only | 4 (15%) |
| Double-patenting + other | 1 (4%) |
| Multi-statute (no §101) | 12 (44%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
