18 pending office actions • 7 art units • 14 examiners • 0 of 18 (0%) have an AI response strategy ready • 37 patents granted in the last 365 days
Johnson Matthey plc currently manages 17 pending office actions within the Chemistry & Materials technology area. This portfolio is distributed across 7 distinct art units, indicating a range of technical subject matter within the sector. The prosecution workload involves 14 distinct examiners, which suggests that the company interacts with a variety of examining styles at the patent office.
BAUM, ZACHARY JOHN is identified as the busiest examiner for this portfolio, currently handling 2 pending office actions. While this examiner has the highest individual count, the total pending actions are spread widely, as evidenced by the distinct examiners involved. Practitioners should note that the 7 distinct art units require specialized knowledge across different chemical classifications. The presence of 17 pending office actions and 14 distinct examiners reflects a distribution of cases per individual official, which may lead to varied prosecution outcomes across the Chemistry & Materials portfolio.
Based on the USPTO statutory response window for each pending office action. 4 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 4 of the docket's apps have a known mailing date.
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 | 8 (44%) |
| §112 only | 1 (6%) |
| Double-patenting + other | 2 (11%) |
| Multi-statute (no §101) | 7 (39%) |
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.
