Technology area: Chemistry & Materials
4 pending office actions • 2 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready • 4 patents granted in the last 365 days
Pacific Industrial Development Corporation has 4 pending office actions in the Chemistry & Materials technology area. The portfolio's prosecution involves 4 distinct examiners, although these examiners are housed within 2 distinct art units. This structure suggests that while the technology is concentrated in specific areas, the patent office has assigned multiple individuals to review the filings. This can lead to a situation where the company receives varied feedback on technical concepts, depending on which examiner is reviewing the case.
The busiest examiner for the company is NGUYEN, HAIDUNG D, who is responsible for 1 busiest examiner pending action. With several individuals involved in the 4 pending office actions, the workload is distributed. However, the concentration in 2 distinct art units means that the company can focus its strategy on the specific policies of those administrative groups while still addressing the individual preferences of the 4 distinct examiners. This balance of examiner diversity and art unit concentration requires a coordinated prosecution approach to ensure consistency across the portfolio.
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 (25%) |
| Multi-statute (no §101) | 3 (75%) |
