De Nora Permelec Ltd. currently manages a portfolio within the Chemistry & Materials technology area. The company has 2 pending office actions across its active filings. This volume suggests an active engagement with the patent office in this technical field.
The prosecution work is distributed across 2 distinct examiners and 2 distinct art units. This distribution between examiners and art units indicates that the company's intellectual property is being reviewed by different specialized groups rather than being concentrated under a specific administrative path.
SYLVESTER, KEVIN is identified as the busiest examiner for this portfolio, currently handling 1 pending office action. Because this examiner is responsible for some of the total 2 pending office actions, their specific examination style and history will influence the outcomes for the company's applications. Practitioners should monitor the examiner's past allowances to gauge the likelihood of success. The presence of 2 distinct art units suggests that the pending office actions involve different sub-specialties within Chemistry & Materials.
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%) |
| Double-patenting + other | 1 (50%) |
