Kemira Oyj has 7 pending office actions in Chemistry & Materials. The matters involve 7 distinct examiners and 5 distinct art units, indicating broad examiner coverage with repeated art-unit assignments.
MINSKEY, JACOB T is the busiest examiner, with 1 pending matter. Portfolio review can use shared art-unit context to identify recurring technical issues while retaining separate examiner-focused responses.
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 |
|---|---|
| §101 + other | 2 (29%) |
| §103 only | 1 (14%) |
| Multi-statute (no §101) | 4 (57%) |
