LT Materials Co., Ltd. has 39 pending office actions in Chemistry & Materials. The docket spans 19 examiners and 9 art units, making examiner and unit coordination a central prosecution issue. The difference between the action volume and the number of examining groups indicates that some units handle multiple active matters, even though the data does not identify those allocations individually.
SIMBANA, RACHEL A is the busiest examiner, with 4 pending matters. Counsel should prioritize docket segmentation, recurring objection analysis, and consistent amendment positions while preserving matter-specific response records.
Based on the USPTO statutory response window for each pending office action. 7 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. 7 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 | 15 (41%) |
| §102 only | 6 (16%) |
| Double-patenting + other | 1 (3%) |
| Multi-statute (no §101) | 15 (41%) |
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.
