50 pending office actions • 25 art units • 42 examiners • 0 of 50 (0%) have an AI response strategy ready • 57 patents granted in the last 365 days
PPG Industries Inc. has 48 pending office actions in Chemistry & Materials. These matters span 42 distinct examiners and 25 distinct art units, reflecting a broad prosecution footprint rather than a narrow examination queue. The spread across examiners is substantial, while the art-unit distribution indicates that related work may still be grouped for internal review.
WEDDLE, ALEXANDER MARION is the busiest examiner, with 2 pending matters. That concentration is limited relative to the portfolio's overall examiner distribution, so docket management should emphasize consistent claim-development practices, art-unit monitoring, and application-specific response preparation.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 only | 1 (2%) |
| §101 + other | 1 (2%) |
| §103 only | 28 (56%) |
| §102 only | 1 (2%) |
| §112 only | 1 (2%) |
| Double-patenting + other | 3 (6%) |
| Multi-statute (no §101) | 15 (30%) |
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.
