China University of Mining and Technology has 4 pending office actions within the Chemistry & Materials technology area. These actions are spread across 2 distinct art units, indicating that the university's research covers multiple technical niches. The prosecution involves 4 distinct examiners, which means that every pending action is being handled by a different person. JOHN J DERUSSO is the busiest examiner for the university, currently responsible for 1 pending office action.
This indicates a fragmented examiner pool, as each of the distinct examiners is managing 1 pending office action. Practitioners must navigate the preferences of different examiners while maintaining consistency across the 2 distinct art units involved. The presence of the 4 pending office actions reflects a steady level of activity in the Chemistry & Materials sector for the institution. Managing the distinct examiners requires a versatile approach to prosecution, as each person may have different interpretations of the prior art. The concentration of the actions within the 2 distinct art units suggests that while the examiners are different, the technical subject matter is relatively clustered. This allows for some synergy in technical arguments even when dealing with examiners like JOHN J DERUSSO. Coordinating these distinct examiners is essential for a cohesive portfolio strategy.
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.
| Bucket | Cases |

| §103 only | 1 (25%) |
| §112 only | 1 (25%) |
