Analysis

Suzhou 3N Biological Technology Co. Ltd. currently manages 2 pending office actions within the Chemistry & Materials technology area. These active matters are assigned to 2 distinct examiners, but both are located within 1 distinct art unit. This concentration within 1 distinct art unit indicates that the company's current filings are technically similar, despite being reviewed by different individuals.

The busiest examiner for the company is COLLINS, DARRYL J, who is handling 1 pending office action. Since the busiest examiner pending count is 1 and there are 2 pending office actions in total, the workload is evenly split between the 2 distinct examiners. This distribution means that no single examiner is responsible for more than 1 active case for the company at this time.

For a patent practitioner, this data suggests that Suzhou 3N Biological Technology Co. Ltd. must manage 2 separate examiner relationships within the same art unit. The focus on Chemistry & Materials is consistent across the 2 pending office actions. This setup requires a prosecution strategy that accounts for the specific review styles of 2 distinct examiners while navigating the standards of 1 distinct art unit.
