Technology area: Chemistry & Materials
33 pending office actions • 22 art units • 30 examiners • 0 of 33 (0%) have an AI response strategy ready • 52 patents granted in the last 365 days
Lawrence Livermore National Security LLC is managing 32 pending office actions in the Chemistry & Materials technology area. The prosecution is decentralized, with 29 distinct examiners involved in reviewing the applications. This diversity is further reflected in the 21 distinct art units where these actions are pending, indicating a very broad range of chemical and material research. The company must manage a vast array of examiner interactions and art unit specificities to advance its 32 pending office actions.
KEELING, ALEXANDER W is the busiest examiner for the company, yet only holds 2 pending office actions. This low concentration among 29 distinct examiners highlights the wide distribution of the 32 pending office actions. Navigating 21 distinct art units requires the company to adapt to a vast array of technical standards and examiner expectations across the USPTO. With 29 distinct examiners involved, the company rarely encounters the same examiner twice, necessitating a highly individualized strategy for almost every pending case in the Chemistry & Materials field across the 21 distinct art units.
Based on the USPTO statutory response window for each pending office action. 16 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. 16 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 (3%) |
| §103 only | 5 (15%) |
| §102 only | 2 (6%) |
| §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.
