Purigen Biosystems Inc. maintains 2 pending office actions within the Chemistry & Materials technology area. These actions are distributed across 2 distinct examiners, which suggests a diversified approach to prosecution even with a small number of active files. The involvement of 2 distinct art units further indicates that the company's research interests in this sector span multiple specialized classifications within the patent office.
The busiest examiner, WRIGHT, PATRICIA KATHRYN, is currently handling 1 pending office action. This workload is shared with another examiner who manages the remaining action. For patent practitioners, this distribution means that prosecution strategies must be tailored to two different examiner styles simultaneously. The balance between the 2 distinct examiners and the total pending workload prevents any single examiner from dominating the portfolio's current trajectory.
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 | 1 (50%) |
| Multi-statute (no §101) | 1 (50%) |
