FuelCell Energy Inc. maintains a company patent portfolio in the Chemistry & Materials technology area. There are currently 2 pending office actions within this portfolio. These actions are assigned to 2 distinct examiners, yet they are both located within 1 distinct art unit.
The busiest examiner, WITTENBERG, STEFANIE S, is currently handling 1 busiest examiner pending office action. Because the workload is shared, the examiners each manage a single case. This arrangement in a single art unit allows the applicant to focus on the specific standards of a single technical division while interacting with different examiners.
For the practitioner, managing these pending office actions within 1 distinct art unit provides an opportunity for consistency in technical arguments. Although there are multiple examiners, the shared art unit environment often implies a unified supervisory structure. This Chemistry & Materials portfolio demonstrates how multiple active matters can be concentrated within a single organizational segment.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 1 (50%) |
| Multi-statute (no §101) | 1 (50%) |
