The Charles Stark Draper Laboratory Inc. manages 18 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are spread across 18 distinct examiners, resulting in a one-to-one ratio of actions to examiners. The portfolio is further distributed across 11 distinct art units, showing a broad technical range within the mechanical and medical fields.
WEISFELD, MATTHIAS S is the busiest examiner for the laboratory, currently responsible for 1 pending office action. Given that there are 18 distinct examiners for 18 total actions, every examiner currently assigned to the portfolio holds exactly one case. The 11 distinct art units suggest that the laboratory's research is being evaluated by a wide variety of specialized technical groups, requiring a diverse prosecution strategy.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 |
|---|---|
| §101 only | 1 (5%) |
| §101 + other | 2 (11%) |
| §103 only | 6 (32%) |
| §102 only | 1 (5%) |
| §112 only | 1 (5%) |
| Double-patenting + other | 1 (5%) |
| Multi-statute (no §101) | 7 (37%) |
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.
