ExxonMobil currently has 15 pending office actions within the Chemistry & Materials technology area. These actions are being handled by 11 distinct examiners, indicating that some examiners are managing multiple files for the company. The prosecution is organized across 4 distinct art units, which suggests a concentration of the company's chemical and material innovations within specialized USPTO groups.
The busiest examiner for this portfolio is NGUYEN, TAM M, who is currently responsible for 3 pending office actions. This represents a portion of the 15 total pending actions. With 11 distinct examiners in total, the workload is distributed such that NGUYEN, TAM M handles more matters than other examiners assigned to this portfolio.
Practitioners should note that while there are the distinct examiners, the 4 distinct art units indicate that the pending actions are technically focused. The busiest examiner, NGUYEN, TAM M, manages 3 actions, while the remaining actions are distributed among the other examiners. This structure requires a strategy that accounts for both the influence of specific examiners and the requirements of the specialized art units.
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 | 7 (44%) |
| Double-patenting + other | 2 (12%) |
| Multi-statute (no §101) | 7 (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.
