Law Office of Katsuhiro Arai has 27 pending office actions in Chemistry & Materials and 1369 career applications. The pending docket is active, and the application history supplies a substantial basis for reviewing prosecution activity in this technology area.
The resolved allowance rate is 89.08%, with an average of 2.82 office actions per allowance. The allowance rate describes resolved outcomes, while the average indicates the examination activity tied to allowed matters. For practitioners, these figures support workload planning and response preparation, especially where multiple matters may require coordinated claim and prior-art analysis.
Based on the USPTO statutory response window for each pending office action. 2 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 |
|---|---|
| §103 only | 8 (31%) |
| §102 only | 4 (15%) |
| §112 only | 1 (4%) |
| Multi-statute (no §101) | 13 (50%) |
How the docket's pending cases split across USPTO tech-center bands.
