Sagami Chemical Research Institute has 3 pending office actions in Chemistry & Materials. The matters span 3 distinct examiners and 3 distinct art units, showing that the pending portfolio is distributed across separate examination channels.
HOBAN, MATTHEW E is the busiest examiner, with 1 pending matter. Counsel should review each matter against its own examiner and art-unit context rather than treating the portfolio as a single examination stream.
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 | 1 (33%) |
| §112 only | 1 (33%) |
| No statute on record | 1 (33%) |
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.
| Examiner | Apps on this docket | Allow rate | Interview lift |
|---|---|---|---|
| HOBAN, MATTHEW E | 1 | 60.4% | +25.6% |
| YOO, SUN JAE | 1 | 71.2% | +0.3% |
| ZHANG, KELING NMN | 1 | 66.8% | +17.6% |
Cases in front of an examiner whose interview lift is 10 percentage points or more — i.e. interviewed cases historically resolve more favorably than non-interviewed ones. The top 2 ordered by deadline are shown.
