Calgon Carbon Corporation maintains a portfolio in the Chemistry & Materials technology area. There are 4 pending office actions currently active. These actions are distributed across 4 distinct examiners and 2 distinct art units, indicating that the company's current filings are being reviewed by a variety of individuals.
SPIES, BRADLEY R is identified as the busiest examiner, with 1 busiest examiner pending office action. Since there are 4 pending office actions and 4 distinct examiners, each examiner is responsible for a single action. The 2 distinct art units suggest that the 4 pending actions are divided between different technical groups within the Chemistry & Materials area.
For practitioners, this distribution means that no single examiner has a dominant influence over the portfolio's current prosecution. With 4 distinct examiners for 4 pending office actions, the outcomes are likely to be independent. The presence of 2 distinct art units requires monitoring different sets of technical standards, with SPIES, BRADLEY R handling 1 busiest examiner pending action.
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 |
