Saint-Gobain Placo has 12 pending office actions in the Chemistry & Materials technology area. These actions are handled by 12 distinct examiners across 6 distinct art units. ELIZABETH A COLLISTER is the busiest examiner for the portfolio, with 1 pending action. Since there are 12 distinct examiners for 12 pending office actions, every pending matter is assigned to a different individual.
The 6 distinct art units show that the company's chemical and material filings are distributed across several specialized technical groups at the USPTO. This variety in 6 distinct art units indicates that the company's innovations cover multiple distinct technical classifications within its primary technology area. With 12 pending office actions, the company is actively engaged in the patent acquisition process. The use of 12 distinct examiners means that the company's legal representatives must manage a range of individual examiner styles and preferences. The distribution across 6 distinct art units suggests a balanced portfolio that reflects a focused yet diverse approach to chemical research and development.
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 (9%) |
| §103 only | 6 (55%) |
