Proterial Ltd. maintains a significant presence in the Semiconductors, Circuits & Optics technology area with 42 pending office actions. These 42 pending office actions are distributed among 36 distinct examiners, showing a broad spread of prosecution activity. The portfolio is remarkably diverse, spanning 23 distinct art units, which suggests a wide array of technical applications within the semiconductor and optics sectors. This high number of 23 distinct art units indicates that the company's innovations are being reviewed by many different supervisory groups.
The busiest examiner for the company is NGUYEN, CHAU N, who is currently managing 3 pending office actions. While NGUYEN, CHAU N has the highest individual workload, the use of 36 distinct examiners means that the vast majority of the 42 pending office actions are being reviewed independently. Practitioners must account for the high number of 23 distinct art units when managing this portfolio, as it indicates a very broad technical footprint at the patent office. With 42 pending office actions in play, the company faces a complex task in maintaining a unified legal strategy across 36 distinct examiners. The distribution of 42 pending office actions across so many units and examiners highlights the scale of the company's current intellectual property efforts.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 | 1 (2%) |
| §103 only | 22 (50%) |
| §102 only | 3 (7%) |
| §112 only | 1 (2%) |
| Multi-statute (no §101) | 17 (39%) |
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.
