Diversey Inc. has 5 pending office actions in the Chemistry & Materials technology area. Each of these 5 actions is assigned to a different person, resulting in 5 distinct examiners for the portfolio. These matters are spread across 3 distinct art units, which indicates that the company's chemistry filings are reviewed by several different technical groups at the USPTO. The distribution across 3 distinct art units suggests that the 5 pending office actions cover a variety of specific chemistry or materials applications.
Hai Y Zhang is the busiest examiner for the company with 1 pending office action. Because there are 5 distinct examiners for the 5 total actions, there is no overlap in examiner assignments. The 3 distinct art units involved show that the 5 pending office actions are distributed across multiple specialized units. This structure requires the company to navigate 5 different individual examination styles. Practitioners should develop unique strategies for each of the 5 pending office actions to address the specific feedback from each assigned examiner within the Chemistry & Materials sector.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 2 (40%) |
| Multi-statute (no §101) | 3 (60%) |
