Johnson Matthey Hydrogen Technologies Limited has 2 pending office actions in Chemistry & Materials. The matters involve 2 distinct examiners across 2 distinct art units, indicating that the pending work is distributed rather than concentrated within a single examination assignment.
MURPHY, RYAN PATRICK is the busiest examiner, with 1 pending matter. Counsel should therefore evaluate the matters by examiner and art unit, while maintaining a coordinated position on the portfolio’s chemistry and materials claims.
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 |
|---|---|
| Double-patenting + other | 1 (50%) |
| Multi-statute (no §101) | 1 (50%) |
