Technology area: Chemistry & Materials
3 pending office actions • 1 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 8 patents granted in the last 365 days
Zhengzhou University has 3 pending office actions in the Chemistry & Materials technology area. These 3 actions are assigned to 3 distinct examiners, but all are located within 1 distinct art unit. This creates a situation where the technical field is highly concentrated, but the individual reviewers are diverse. KOSACK, JOSEPH R is the busiest examiner, holding 1 pending office action.
The presence of 3 distinct examiners for only 3 pending office actions means there is no examiner overlap. KOSACK, JOSEPH R is one of three individuals each handling a single action. Despite this, the 1 distinct art unit indicates that all 3 pending actions are classified within the same technical area of Chemistry & Materials.
For a practitioner, this profile suggests that while the technical arguments may be similar across the 3 pending office actions, they must be tailored to 3 different examiners. The 1 distinct art unit provides a very narrow technical focus for the portfolio. KOSACK, JOSEPH R and his colleagues each manage 1 of the 3 active matters, requiring a unified technical strategy across 3 distinct examiners.
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 |
|---|---|
| Multi-statute (no §101) | 3 (100%) |
