Analysis

Omya International AG is managing 24 pending office actions in the Chemistry & Materials technology area. These 24 actions are handled by 24 distinct examiners, meaning no examiner is currently reviewing more than one application for the company. These matters are distributed across 14 distinct art units, which suggests a diverse range of technical filings within the chemistry sector.

MINSKEY, JACOB T is identified as the busiest examiner for this portfolio, with 1 pending office action. The company must navigate 14 different art units without the benefit of examiner-level consolidation, as every single one of the 24 pending actions is assigned to a different individual. This one-to-one ratio of actions to examiners across 14 art units indicates a highly decentralized prosecution environment. Practitioners should be prepared for a wide variety of examiner perspectives, as no single examiner's habits will dominate the outcomes for this Chemistry & Materials portfolio.
