45 pending office actions • 19 art units • 40 examiners • 0 of 45 (0%) have an AI response strategy ready • 64 patents granted in the last 365 days
DuPont de Nemours Inc. maintains a substantial prosecution pipeline with 45 pending office actions in the Chemistry & Materials technology area. This large volume of activity is highly distributed, involving 40 distinct examiners and 19 distinct art units. Such a broad distribution indicates that the company's chemical innovations span a wide array of specialized technical fields, requiring engagement with 19 different divisions at the patent office.
REDDY, KARUNA P is the busiest examiner for the portfolio, currently overseeing 3 pending office actions. Despite the high total of 45 actions, the workload is spread so thinly that even the busiest examiner handles only a small portion of the total. With 40 distinct examiners involved, the company must manage a vast number of individual examiner relationships and diverse sets of feedback. The use of 19 distinct art units further underscores the technical complexity and variety of the portfolio, requiring practitioners to be well-versed in the specific guidelines of many different specialized units. This complex structure necessitates a highly organized and consistent prosecution strategy to manage the large volume of active matters across such a diverse range of examiners and art units.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 | 1 (2%) |
| §103 only | 15 (33%) |
| §112 only | 5 (11%) |
| Double-patenting + other | 3 (7%) |
| Multi-statute (no §101) | 21 (47%) |
How the docket's pending cases split across USPTO tech-center bands.
