Technology area: Chemistry & Materials
2 pending office actions • 2 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Qingyou Han has 2 pending office actions in the Chemistry & Materials technology area. These 2 actions are being handled by 2 distinct examiners across 2 distinct art units. This means each pending matter is assigned to a different examiner and a different administrative group, resulting in a completely fragmented prosecution environment for this small portfolio. The lack of overlap between the cases suggests that the innovations being protected are technically distinct.
JANSSEN, REBECCA is identified as the busiest examiner, though she is responsible for only 1 pending office action. This reflects the complete dispersion of the 2 pending actions between the 2 distinct examiners. The use of the 2 distinct art units shows that these chemical and material filings are being reviewed in separate specialized areas of the patent office. For practitioners, this means there is no overlap in either examiner or art unit for the current pending matters. The busiest examiner is responsible for 1 pending office action.
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.
