11 pending office actions • 5 art units • 9 examiners • 0 of 11 (0%) have an AI response strategy ready • 19 patents granted in the last 365 days
Yara International ASA manages a portfolio with 11 pending office actions in the Chemistry & Materials technology area. This workload is widely distributed across 9 distinct examiners and 5 distinct art units, suggesting a broad range of technical subject matter and a diverse prosecution front. The high number of 11 pending office actions indicates a very active period of engagement with the USPTO for the company's chemistry-related innovations.
The busiest examiner for the portfolio is LANGEL, WAYNE A, who is currently handling 2 pending office actions. This relatively low number for a busiest examiner, compared to the total volume of work, highlights the high degree of examiner diversity. With 5 distinct art units involved, the company must navigate various examination styles and technical standards across the USPTO's chemistry divisions. Managing 9 distinct examiners requires a highly organized approach to ensure consistency in arguments across the pending matters, even when the busiest examiner oversees a small portion of the total workload.
Based on the USPTO statutory response window for each pending office action. 2 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 |
|---|---|
| §101 only | 1 (9%) |
| §103 only | 4 (36%) |
| §102 only | 2 (18%) |
| Multi-statute (no §101) | 4 (36%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
