Technology areas: Biotechnology & Pharmaceuticals • Chemistry & Materials
28 pending office actions • 25 art units • 28 examiners • 0 of 28 (0%) have an AI response strategy ready • 13 patents granted in the last 365 days
Drexel University has 26 pending office actions in Chemistry & Materials. Those matters are distributed among 26 examiners and 23 art units, showing a broad prosecution footprint across the technology area rather than concentration in one examination group.
ELHILO, EISA B is the busiest examiner, with 1 pending matter. Because no examiner accounts for more than that figure in the supplied data, portfolio management should emphasize coordination across many individual prosecution matters instead of relying on a single examiner relationship.
The spread across examiners and art units suggests that claim strategy, disclosure support, and response timing may need to be tracked at the application level. Technical teams should maintain consistent terminology across the Chemistry & Materials portfolio while adapting arguments to the specific art unit record for each matter.
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 + other | 2 (7%) |
| §103 only | 9 (32%) |
| §102 only | 2 (7%) |
| §112 only | 2 (7%) |
| Double-patenting + other | 2 (7%) |
| Multi-statute (no §101) | 11 (39%) |
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.
