Technology area: Chemistry & Materials
3 pending office actions • 2 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Gkn Sinter Metals LLC manages 3 pending office actions within the Chemistry & Materials technology area. These actions are distributed among 3 distinct examiners across 2 distinct art units. HEVEY, JOHN A is the busiest examiner for this portfolio, holding 1 pending office action. The distribution of 3 pending office actions across 3 distinct examiners suggests that each matter is being reviewed by a different individual.
The involvement of 2 distinct art units indicates that the company's innovations span different technical sub-fields. This variety requires a prosecution strategy that can adapt to different art unit norms and examiner styles. With 3 distinct examiners involved, the company can observe a range of examiner behaviors, even though JOHN A HEVEY is the only one identified as the busiest with 1 pending office action. This decentralized approach reduces the impact of any single examiner's perspective on the overall portfolio.
Practitioners should note that the Chemistry & Materials technology area often requires navigating specific material standards. Having 3 pending office actions across 2 distinct art units provides a broader view of how the USPTO perceives the company's technical disclosures. While the portfolio is currently managed by 3 distinct examiners, the coordination of these matters is essential to maintain consistency. The current data reflects an active engagement across multiple technical groups within the patent office.
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 |
|---|---|
| Double-patenting + other | 1 (33%) |
| Multi-statute (no §101) | 2 (67%) |
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.
