LANXESS Deutschland GmbH has 11 pending office actions in Chemistry & Materials. The matters involve 10 distinct examiners and 10 distinct art units, showing a broad distribution of examination responsibility with some concentration in the overall workload. BARCENA, CARLOS is the busiest examiner, handling 2 pending actions.
The difference between the pending-action count and the examiner and art-unit counts means that at least one assignment contains more than a single pending action, although the available data does not identify the other concentration. Portfolio management should use a centralized docket for deadlines while tailoring responses to each technical unit. The BARCENA matters merit coordinated review for recurring claim or disclosure issues.
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 | 2 (18%) |
| §103 only | 3 (27%) |
| §112 only | 2 (18%) |
| Double-patenting + other | 2 (18%) |
| Multi-statute (no §101) | 2 (18%) |
