Tessenderlo Group NV currently manages 6 pending office actions within the Chemistry & Materials technology area. This workload is distributed across 4 distinct examiners and 4 distinct art units. This distribution of actions across the examiners relative to the 6 total actions indicates the level of concentration in the company's prosecution focus. The review process is situated within the Chemistry & Materials sector, where the art units define the administrative scope. Such a structure suggests that the company's intellectual property in this sector is being reviewed by specific administrative paths, which can influence the consistency of feedback from the patent office.
The busiest examiner for this portfolio is LANGEL, WAYNE A, who is responsible for 3 pending office actions. This individual handles 3 actions out of the total pending for the company. For practitioners, the involvement of 4 distinct examiners across 4 art units provides a specific map of the current prosecution landscape. This concentration or dispersion of matters requires a tailored approach to examiner interviews and response strategies to ensure that the technical arguments remain effective across all active files.
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 |
|---|---|
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 5 (83%) |
