Purina Animal Nutrition LLC currently manages 6 pending office actions within the Chemistry & Materials technology area. These actions are assigned to 6 distinct examiners. The prosecution is occurring across 4 distinct art units, which shows that the company's filings are being evaluated by several different technical sections at the patent office.
The busiest examiner, PEEBLES, KATHERINE, is responsible for 1 pending office action. Since there are 6 pending office actions and 6 distinct examiners, every examiner is currently handling exactly one action. The 4 distinct art units indicate that some examiners are working within the same technical groups while others are in different ones. This distribution across 6 distinct examiners ensures a variety of perspectives on the Chemistry & Materials applications.
Practitioners should observe that the 6 pending office actions are evenly distributed at the examiner level. Because PEEBLES, KATHERINE only manages 1 pending action, no single examiner has a dominant role in the portfolio. The 4 distinct art units provide the technical framework for these evaluations. This spread across 6 distinct examiners and 4 distinct art units suggests a decentralized prosecution environment for Purina Animal Nutrition LLC.
Based on the USPTO statutory response window for each pending office action. 3 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 3 of the docket's apps have a known mailing date.
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 | 4 (67%) |
| Multi-statute (no §101) | 2 (33%) |
