Hydrogenics Corporation has 9 pending office actions in Chemistry & Materials. The matters involve 9 examiners and 9 art units, showing that every active assignment is spread across a distinct examiner and technical unit in the available profile. This structure increases the importance of centralized docket control without implying that the underlying claim issues are the same.
JONES, OLIVIA ANN is the busiest examiner, with 1 pending matter. Since the busiest assignment is limited to that figure, counsel should emphasize separate examiner analysis and consistent portfolio-level recordkeeping.
Based on the USPTO statutory response window for each pending office action. 2 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 | 1 (11%) |
| §103 only | 4 (44%) |
| Multi-statute (no §101) | 4 (44%) |
How the docket's pending cases split across USPTO tech-center bands.
