150 pending office actions • 35 art units • 135 examiners • 0 of 150 (0%) have an AI response strategy ready • 317 patents granted in the last 365 days
Rohm Co., Ltd. has 153 pending office actions in Semiconductors, Circuits & Optics. The portfolio reaches 135 distinct examiners and 36 distinct art units, reflecting extensive examiner dispersion and substantial repetition within the art-unit structure.
NGUYEN, CUONG B is the busiest examiner, with 3 pending matters. The limited examiner concentration places greater emphasis on art-unit-level coordination, consistent claim strategy, and systems that can track prosecution developments across a large number of matters.
Based on the USPTO statutory response window for each pending office action. 27 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. 27 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 |
|---|---|
| §101 + other | 2 (1%) |
| §103 only | 51 (34%) |
| §102 only | 15 (10%) |
| §112 only | 6 (4%) |
| Double-patenting only | 3 (2%) |
| Double-patenting + other | 1 (1%) |
| Multi-statute (no §101) | 68 (45%) |
| No statute on record | 4 (3%) |
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.
