154 pending office actions • 37 art units • 131 examiners • 0 of 154 (0%) have an AI response strategy ready • 306 patents granted in the last 365 days
Rohm Co., Ltd. manages 148 pending office actions in the Semiconductors, Circuits & Optics technology area. These actions are distributed across 25 distinct art units. This spread across 25 art units indicates that the company's semiconductor innovations are being reviewed by a wide range of specialized technical groups at the patent office.
The company interacts with 133 distinct examiners. IMTIAZ, ZOHEB S is the busiest examiner, overseeing 2 pending actions. The high number of 133 examiners for 148 actions indicates that very few examiners are handling more than one case for the company. This results in a very low level of examiner concentration, with the vast majority of the 148 actions being reviewed by unique individuals.
Managing 148 pending office actions with 133 different examiners across 25 art units presents a significant coordination challenge. Because the busiest examiner, IMTIAZ, ZOHEB S, only handles 2 actions, the company cannot rely on building deep relationships with specific examiners to drive consistency. Practitioners must be prepared for 133 different examination styles across the company's semiconductor portfolio.
Based on the USPTO statutory response window for each pending office action. 25 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. 25 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 | 50 (32%) |
| §102 only | 17 (11%) |
| §112 only | 4 (3%) |
| Double-patenting only | 4 (3%) |
| Double-patenting + other | 1 (1%) |
| Multi-statute (no §101) | 73 (47%) |
| No statute on record | 3 (2%) |
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.
