13 pending office actions • 4 art units • 5 examiners • 0 of 13 (0%) have an AI response strategy ready • 3 patents granted in the last 365 days
Ohara Inc. demonstrates a concentrated prosecution strategy within the Chemistry & Materials technology area. The company currently has 13 pending office actions, which are handled by 5 distinct examiners. This indicates that while the company has a significant number of active applications, the pool of examiners reviewing them is relatively small.
The workload is spread across 4 distinct art units, suggesting some technical variety within their chemistry-focused filings. However, a major point of concentration exists with the busiest examiner, COLGAN, LAUREN ROBINSON, who is responsible for 9 pending office actions. This means that a single individual is overseeing the majority of the company's 13 pending office actions.
For a practitioner, this concentration with a single examiner suggests that the outcomes for a large portion of the portfolio may be highly consistent. The fact that 9 of these actions are with a single person in a portfolio spanning 4 distinct art units is a significant administrative detail for the company's legal strategy.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 3 (23%) |
| Double-patenting + other | 5 (38%) |
| Multi-statute (no §101) | 5 (38%) |
