88 pending office actions • 40 art units • 78 examiners • 0 of 88 (0%) have an AI response strategy ready • 140 patents granted in the last 365 days
Compagnie de Saint-Gobain S.A. maintains a substantial presence in the Chemistry & Materials technology area with 97 pending office actions. This volume of active prosecution is spread across 84 distinct examiners and 41 distinct art units. The count of 41 distinct art units reflects a broad technical footprint, requiring the company to manage relationships and strategies across a wide swath of the patent office's organizational structure.
KHAN, TAHSEEN is the busiest examiner for this portfolio, currently handling 5 pending office actions. While this is the highest concentration for any single examiner, these 5 actions represent a small portion of the 97 total pending office actions. The distribution across 84 distinct examiners suggests that the vast majority of cases are being handled individually, limiting the impact that any single examiner's tendencies might have on the overall portfolio.
The ratio of 97 pending office actions to 41 distinct art units indicates that many units are handling multiple cases for the company. However, with 84 distinct examiners involved, there is significant variety in the individual perspectives reviewing the applications. Practitioners must account for this wide distribution when coordinating prosecution strategies, as the 41 distinct art units will likely apply varying interpretations of chemistry-related patentability standards.
Based on the USPTO statutory response window for each pending office action. 28 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. 28 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 (1%) |
| §101 + other | 1 (1%) |
| §103 only | 34 (39%) |
| §102 only | 1 (1%) |
