DuPont Nutrition Biosciences APS maintains a portfolio with 19 pending office actions in the Chemistry & Materials technology area. These actions are distributed among 18 distinct examiners. The workload spans 11 distinct art units, showing the reach across different technical examination groups at the USPTO. This count of 11 distinct art units suggests that the company's research and development in Chemistry & Materials touches upon many different specialized fields.
MUKHOPADHYAY, BHASKAR is the busiest examiner for this portfolio, managing 2 busiest examiner pending office actions. While this examiner has the highest individual count, the 2 actions represent a portion of the 19 pending office actions total, reflecting a diversified prosecution strategy. With 18 distinct examiners involved, the company must manage a variety of examiner styles and preferences across its 19 pending office actions.
The distribution of 19 pending office actions across 18 distinct examiners and 11 distinct art units requires a management approach to ensure consistency in claim language and prosecution arguments. Because MUKHOPADHYAY, BHASKAR only handles 2 busiest examiner pending office actions, the majority of the portfolio is subject to the independent discretion of the other examiners. This structure limits the impact that any single examiner's tendencies might have on the overall success of the company's patenting efforts.
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 |
|---|---|
| §103 only | 8 (44%) |
| §112 only | 1 (6%) |
| Multi-statute (no §101) | 9 (50%) |
