Analysis

Sunresin New Materials Co., Ltd. manages 5 pending office actions within the Chemistry & Materials technology area. Each of these 5 actions is assigned to a different individual, resulting in 5 distinct examiners for the portfolio. This distribution is mirrored in the organizational structure, as the 5 actions are also spread across 5 distinct art units. PETER KEYWORTH is the busiest examiner, currently holding 1 pending office action.

The ratio between pending office actions, distinct examiners, and distinct art units suggests a fragmented prosecution landscape. With 5 distinct examiners and 5 distinct art units involved, there is no consolidation of matters under a single authority. Practitioners must manage separate examination processes, each potentially following different procedural nuances within their respective art units. This profile shows that the 5 pending office actions represent unique technical paths within the Chemistry & Materials sector.
