Technology area: Chemistry & Materials
10 pending office actions • 8 art units • 9 examiners • 0 of 10 (0%) have an AI response strategy ready • 10 patents granted in the last 365 days
Primearth Ev Energy Co. Ltd. maintains a robust and technically diverse patent portfolio within the Chemistry & Materials technology area. The company is currently managing 10 pending office actions, indicating a high level of ongoing prosecution activity. This workload is distributed across 9 distinct examiners, which provides a broad range of perspectives on the company's applications. PILLAY, DEVINA is the busiest examiner, currently handling 2 pending office actions, while the remaining 8 actions are spread among other officials.
The technical breadth of the portfolio is further demonstrated by the involvement of 8 distinct art units. This high number of art units relative to the 10 pending office actions suggests that the company's innovations span multiple specialized sub-fields. For practitioners, this distribution requires a highly adaptable strategy, as each of the 8 art units may have its own specific examination standards. The fact that 9 distinct examiners are involved means the company must manage a variety of individual examiner preferences across its pending matters.
With 10 pending office actions and 8 distinct art units, the company has a complex prosecution landscape. Because PILLAY, DEVINA handles 2 pending office actions, her specific feedback has a slightly larger impact than other examiners, but the portfolio remains well-diversified. This structure mitigates the risk of any single examiner's tendencies affecting the entire portfolio. Practitioners should focus on coordinating arguments across the 8 distinct art units to ensure a consistent intellectual property strategy for Primearth Ev Energy Co. Ltd.
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 (40%) |
| Double-patenting + other | 2 (20%) |
| Multi-statute (no §101) | 4 (40%) |
