Sumitomo Bakelite Co., Ltd. has 15 pending office actions in Chemistry & Materials. The matters involve 14 distinct examiners across 12 distinct art units, showing broad distribution with limited examiner overlap and a wide technical spread.
GUERRERO ROSARIO, ANA VERUSKA is the busiest examiner, with 2 pending matters. The repeated assignment supports a focused review of those matters, while the rest of the docket calls for separate examiner and art-unit assessments.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 | 9 (64%) |
| §102 only | 1 (7%) |
| Multi-statute (no §101) | 4 (29%) |
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.
