Lawrence Livermore National Security LLC has 32 pending office actions in Chemistry & Materials. The portfolio spans 29 examiners and 26 art units, indicating broad technical and examination coverage rather than a single prosecution center.
KEELING, ALEXANDER W is the busiest examiner, with 2 pending matters. That limited concentration means examiner-specific coordination will address only a small part of the docket, while art-unit and technology-level tracking should remain central.
The spread across art units creates a need for consistent claim-development and disclosure practices across matters. Counsel may also benefit from identifying recurring issues at the portfolio level without assuming that one examiner’s treatment will apply throughout.
Based on the USPTO statutory response window for each pending office action. 15 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. 15 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 (6%) |
| §103 only | 6 (18%) |
| §112 only | 2 (6%) |
| Double-patenting + other | 3 (9%) |
| Multi-statute (no §101) | 20 (61%) |
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.
