Johnson Matthey plc has 21 pending office actions in Chemistry & Materials. The portfolio spans 17 distinct examiners and 10 distinct art units, indicating broad prosecution activity with repeated examiner and art-unit assignments. The distribution calls for coordination across matters without assuming that every objection reflects the same technical or procedural context.
DAVIS, SHENG HAN is the busiest examiner, with 3 pending matters. Those matters provide a defined cluster for checking recurring claim interpretation, restriction treatment, and amendment effects. The wider examiner and art-unit distribution makes a portfolio-wide record of positions useful for maintaining consistent prosecution objectives.
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 | 11 (55%) |
| §102 only | 1 (5%) |
| §112 only | 1 (5%) |
| Double-patenting + other | 2 (10%) |
| Multi-statute (no §101) | 5 (25%) |
