The Furukawa Battery Co., Ltd. has 4 pending office actions in Semiconductors, Circuits & Optics. The matters involve 4 distinct examiners and 4 distinct art units, indicating a fully distributed examination workload in the available record.
PARK, HYUN D is the busiest examiner, with 1 pending matter. Separate application-level workflows are appropriate, with no recorded examiner concentration requiring a shared response strategy.
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 |
|---|---|
| §101 + other | 2 (50%) |
| §103 only | 1 (25%) |
| Multi-statute (no §101) | 1 (25%) |
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.
