Trinseo Europe GmbH has 4 pending office actions in the Chemistry & Materials technology area. These actions are handled by 4 distinct examiners, which provides a diverse range of individual reviews for the company's applications. The portfolio is spread across 3 distinct art units, indicating that the company's active filings cover several different technical sub-sectors. This distribution ensures that the company's overall prosecution success is not tied to the specific tendencies of any single examiner.
Pak, Hannah J is the busiest examiner for the portfolio, managing 1 pending office action. Since there are 4 pending actions and four distinct examiners, each examiner is responsible for exactly one action. This distribution across 3 distinct art units and multiple examiners means the company must manage several distinct prosecution tracks. Practitioners should monitor the distinct approaches of these examiners to identify any variations in prosecution style across the different technical groups.
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 | 2 (50%) |
| Multi-statute (no §101) | 2 (50%) |
