54 pending office actions • 23 art units • 46 examiners • 0 of 54 (0%) have an AI response strategy ready • 61 patents granted in the last 365 days
Sika Technology AG maintains a substantial presence in the Chemistry & Materials technology area, currently managing 51 pending office actions. This volume of work is distributed across 23 distinct art units, reflecting a broad technical scope within the USPTO. The prosecution effort involves 45 distinct examiners, which indicates that the company navigates a variety of examiner styles and preferences across its applications.
The busiest examiner for this portfolio is LEONARD, MICHAEL L, who is currently handling 4 busiest examiner pending actions. While this is the highest concentration for any individual, these 4 actions are part of the 51 pending office actions total. The other actions are spread among the remaining distinct examiners, suggesting a decentralized prosecution environment where most cases are reviewed independently.
With 23 distinct art units involved, the portfolio faces diverse examination standards across the Chemistry & Materials sector. The presence of 45 distinct examiners relative to 51 pending office actions means that examiners are handling few cases each for the company. This diversity requires a case-by-case approach rather than a unified strategy tailored to a few specific individuals.
Based on the USPTO statutory response window for each pending office action. 19 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. 19 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 (2%) |
| §103 only | 25 (46%) |
| §112 only | 1 (2%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 26 (48%) |
How the docket's pending cases split across USPTO tech-center bands.
