3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 4 patents granted in the last 365 days
Dipsol Chemicals Co. Ltd. has 3 pending office actions in the Chemistry & Materials technology area. These matters are distributed across 3 distinct art units and 3 distinct examiners. JANSSEN, REBECCA is the busiest examiner for the company, currently overseeing 1 pending office action. This indicates that every pending matter is being reviewed by a different examiner in a different art unit, showing a high degree of distribution for a small number of actions.
The involvement of 3 distinct examiners for 3 pending office actions means that prosecution outcomes are independent of any single examiner's tendencies. Furthermore, the 3 distinct art units involved indicate that the company's chemical innovations span multiple technical classifications. Practitioners must be prepared to navigate the specific requirements of these 3 distinct art units. This decentralized structure requires a versatile strategy to address the specific requirements of each examiner and art unit.
With 3 pending office actions, the portfolio is active but manageable. The strategy appears to favor a broad approach, engaging with 3 distinct examiners to secure intellectual property rights. Because no single examiner handles more than 1 pending office action, the company must maintain consistent arguments across the 3 distinct art units to ensure a unified patent portfolio in the Chemistry & Materials sector. Success depends on navigating the diverse expectations of 3 different individuals.
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.
