Hangzhou Cobetter Filtration Equipment Co. Ltd. has 2 pending office actions in the Chemistry & Materials technology area. These actions are split between 2 distinct examiners and 2 distinct art units. GITMAN, GABRIEL E is the busiest examiner, managing 1 pending action.
The distribution of 2 pending office actions across 2 distinct examiners indicates that each active case is being handled by a different individual. Because the busiest examiner pending count is 1, no single examiner is responsible for more than half of the company's current workload. The use of 2 distinct art units further shows that these matters are being processed by different technical groups at the patent office.
For a practitioner, this dispersion means that the company must adapt its arguments to the specific requirements of two different examiners. The presence of 2 distinct art units suggests that the underlying technologies are categorized into separate specialized groups. This variety provides a broader base of examiner feedback, which can be useful for identifying consistent trends or divergent standards across the Chemistry & Materials sector.
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.
