Saint-Gobain Placo has 11 pending office actions in Chemistry & Materials. Those matters involve 11 distinct examiners and 9 distinct art units, showing that the portfolio’s prosecution workload is distributed broadly across examination personnel and groups.
COLLISTER, ELIZABETH A is the busiest examiner, with 1 pending matter. No examiner accounts for a dominant share of the listed workload, so prosecution planning should be organized at the application level rather than around a single examiner relationship.
The spread across examiners and art units makes centralized docket control important. Counsel may benefit from maintaining consistent claim language and amendment positions while adapting responses to the particular examination group handling each application.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 |
|---|---|
| §101 + other | 1 (10%) |
| §103 only | 5 (50%) |
| Multi-statute (no §101) | 4 (40%) |
