Technology area: Semiconductors, Circuits & Optics
12 pending office actions • 7 art units • 12 examiners • 0 of 12 (0%) have an AI response strategy ready • 29 patents granted in the last 365 days
Sumitomo Osaka Cement Co., Ltd. is managing 12 pending office actions in the Semiconductors, Circuits & Optics technology area. These matters are assigned to 12 distinct examiners, which means that every pending case is being reviewed by a different individual. The portfolio spans 7 distinct art units, indicating a variety of technical classifications within the semiconductor field.
NGUYEN, DANNY is the busiest examiner for the company, currently overseeing 1 pending office action. Since the pending actions and examiners are equal in number, the prosecution workload is fully decentralized, with each examiner handling a single case. The distribution across 7 art units shows that while the technology is focused on semiconductors and optics, it touches on several different specialized areas. This assignment of actions to examiners suggests a fragmented review process where no single examiner has a broad view of the company's current filings.
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 | 4 (33%) |
| §102 only | 1 (8%) |
| Double-patenting + other | 1 (8%) |
| Multi-statute (no §101) | 6 (50%) |
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.
