SUMCO Corporation has 7 pending office actions in Chemistry & Materials. The matters involve 7 examiners and 6 art units, showing broad examiner distribution with some art-unit overlap.
WANG, XIAOBEI is the busiest examiner, with 1 pending matter. The lack of a larger examiner concentration supports a distributed prosecution strategy, with oversight organized around recurring technical issues and the handling of individual actions.
The art-unit structure may help counsel compare examination treatment among related matters, even though examiner assignments are distinct. Consistent terminology and disclosure support can be useful, but responses should remain tailored to each action.
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 (14%) |
| §103 only | 3 (43%) |
| Multi-statute (no §101) | 3 (43%) |
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.
