Analysis

Carl Zeiss AG is currently addressing 8 pending office actions within the Semiconductors, Circuits & Optics technology area. All these actions are housed within 1 distinct art unit, showing a concentration of technical subject matter. Despite this concentration, the company deals with 7 distinct examiners, suggesting a variety of individual review styles within that 1 unit. This high number of examiners relative to the pending workload indicates a fragmented review process.

The busiest examiner, MUHAMMAD, KEY, is managing 2 busiest examiner pending actions. With 8 pending office actions in total, the work is spread across MUHAMMAD, KEY and the other distinct examiners. This ratio of 7 distinct examiners to the total workload indicates that Carl Zeiss AG must maintain a flexible prosecution strategy to satisfy the diverse requirements of the examiners assigned to the applications. Practitioners should prepare for 7 distinct examiner perspectives when addressing the applications.
