Technology area: Chemistry & Materials
3 pending office actions • 2 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 4 patents granted in the last 365 days
Constellium Neuf-Brisach currently has 3 pending office actions within the Chemistry & Materials technology area. These matters are distributed across 2 distinct art units, which indicates that the company's technical filings in chemistry are broad enough to trigger review by different administrative groups. This distribution can lead to varying timelines and procedural requirements across the portfolio.
The prosecution involves 3 distinct examiners, meaning each active office action is being handled by a different individual. ALDAZ CERVANTES, MAYELA RENATA is identified as the busiest examiner, currently managing 1 pending office action. This even distribution across 3 distinct examiners suggests that no single examiner has a dominant influence over the company's current patenting efforts.
The use of 2 distinct art units for the 3 pending office actions shows a relatively high level of organizational diversity compared to the baseline of a single unit. Because each of the active matters is assigned to a different examiner, the company must manage separate prosecution tracks within the Chemistry & Materials field.
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.
