11 pending office actions • 6 art units • 9 examiners • 0 of 11 (0%) have an AI response strategy ready • 8 patents granted in the last 365 days
Hengdian Group Dmegc Magnetics Co. Ltd. has a robust prosecution profile with 11 pending office actions in the Chemistry & Materials technology area. These actions are spread across 9 distinct examiners and 6 distinct art units. Such a broad distribution across multiple art units suggests a diverse range of technical applications and a significant administrative footprint within the chemistry and materials sector.
KOSLOW, CAROL M is the busiest examiner for this company, with 2 pending office actions. The fact that 9 distinct examiners are involved for 11 actions shows a high degree of examiner variety, meaning the company must manage many unique examination styles simultaneously. Practitioners must coordinate across 6 different art units, making this a complex portfolio to manage. The high number of distinct art units relative to the 11 pending office actions indicates that the company's magnetics and materials research spans several specialized patent office divisions.
Based on the USPTO statutory response window for each pending office action. 1 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 |
|---|---|
| §101 + other | 2 (18%) |
| §103 only | 1 (9%) |
| §112 only | 4 (36%) |
| Multi-statute (no §101) | 4 (36%) |
