Lummus Technology LLC has 10 pending office actions in Chemistry & Materials. The portfolio involves 8 examiners across 6 art units, showing a substantial workload distributed among several examination teams. The assignments are not confined to one technical unit, so prosecution review should distinguish art-unit-specific treatment from issues that recur across the portfolio.
DOYLE, BRANDI M is the busiest examiner, with 2 pending actions. That examiner relationship warrants coordinated review of claim amendments, cited references, and response timing for the affected matters.
The remaining workload is spread across multiple examiners, which favors a centralized docketing and knowledge-management process. Practitioners can use common technical positions where appropriate, while preserving flexibility for differences in examination history and art-unit practice.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 5 (50%) |
| Double-patenting only | 2 (20%) |
| Multi-statute (no §101) | 3 (30%) |
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.
