Technology area: Chemistry & Materials
3 pending office actions • 2 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 5 patents granted in the last 365 days
Iogen Corporation currently has 3 pending office actions within the Chemistry & Materials technology area. These actions are distributed among 3 distinct examiners, including NGUYEN, TAM M, who is the busiest examiner with 1 pending action. The portfolio's pending matters are spread across 2 distinct art units. This distribution indicates that while the technology area remains consistent, the company's applications are being evaluated by multiple examiners across different administrative units.
Managing 3 pending office actions across 2 distinct art units requires a strategy that accounts for varied examiner perspectives. Because there are 3 distinct examiners involved, including NGUYEN, TAM M, the practitioner must address the specific requirements of each individual. The spread across 2 art units suggests that the company's chemistry and materials innovations fall into different specialized classifications, each governed by its own set of examination standards and procedural expectations.
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 |
|---|---|
| §101 only | 1 (33%) |
| §103 only | 1 (33%) |
| Multi-statute (no §101) | 1 (33%) |
