Technology area: Chemistry & Materials
56 pending office actions • 21 art units • 52 examiners • 0 of 56 (0%) have an AI response strategy ready • 52 patents granted in the last 365 days
Gs Yuasa International Ltd. manages a robust and diverse patent portfolio within the Chemistry & Materials technology area. The company currently faces 56 pending office actions, reflecting a high volume of active prosecution. These actions are distributed across 21 distinct art units, indicating that the company's technical innovations span a wide range of specialized fields within the broader Chemistry & Materials sector. The presence of 21 distinct art units suggests that the company's intellectual property strategy is highly diversified across multiple chemical disciplines.
The prosecution effort involves 52 distinct examiners, which suggests a broad exposure to different examination styles and requirements. VAN KIRK, DUSTIN KENWOOD is the busiest examiner for the portfolio, though they are responsible for only 2 busiest examiner pending actions. This distribution shows that no single examiner holds a significant portion of the 56 pending office actions, requiring the company to manage 52 distinct examiners simultaneously. This decentralized approach reduces the risk associated with any single examiner's decisions but increases the complexity of maintaining a unified prosecution strategy across the Chemistry & Materials portfolio.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 only | 2 (4%) |
| §101 + other | 1 (2%) |
| §103 only | 34 (61%) |
| §102 only | 4 (7%) |
| §112 only | 1 (2%) |
| Multi-statute (no §101) | 14 (25%) |
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.
