PPG Industries Inc. is currently managing 47 pending office actions within the Chemistry & Materials technology area. These actions are handled by 41 distinct examiners, which indicates examiner diversity across the portfolio. This suggests that the 47 pending office actions are largely being reviewed by different individuals, with few examiners handling multiple cases.
The portfolio spans 21 distinct art units, reflecting a technical footprint within the chemistry and materials sector. ALEXANDER MARION WEDDLE is the busiest examiner for the company, though this individual is responsible for 2 pending office actions. This means that even the busiest examiner handles a portion of the 47 total pending office actions.
Practitioners must navigate 21 distinct art units, which involves specialized examination guidelines. The involvement of 41 distinct examiners requires an adaptable prosecution strategy to account for different individual perspectives. Since ALEXANDER MARION WEDDLE manages 2 pending office actions, the portfolio is distributed among many officials, making it important to track examiner-specific trends across the 41 distinct examiners involved.
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 |
|---|---|
| §103 only | 23 (50%) |
| §102 only | 1 (2%) |
| §112 only | 1 (2%) |
| Double-patenting + other | 3 (7%) |
| Multi-statute (no §101) | 18 (39%) |
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.
