Technology area: Biotechnology & Pharmaceuticals
61 pending office actions • 31 art units • 58 examiners • 0 of 61 (0%) have an AI response strategy ready • 68 patents granted in the last 365 days
Bayer Aktiengesellschaft holds a substantial portfolio in the Biotechnology & Pharmaceuticals technology area, currently featuring 61 pending office actions. These actions are being reviewed by 58 distinct examiners, indicating a very high level of individual attention to each application. The prosecution work is spread across 32 distinct art units, which demonstrates the wide technical variety of the company's pending patent applications within the life sciences sector.
KAUFMAN, CLAIRE M is identified as the busiest examiner for this portfolio, with 2 busiest examiner pending actions. Given that there are 61 pending office actions in total, the concentration of work with any single examiner is extremely low. This distribution suggests that the company's patent strategy is subject to a broad cross-section of the patent office rather than a small group of examiners.
The presence of 32 distinct art units highlights the complexity of managing this portfolio. Practitioners must navigate the specific requirements and trends of many different examination groups. With 58 distinct examiners involved, the consistency of prosecution results will depend on individual negotiations. The 2 busiest examiner pending actions with KAUFMAN, CLAIRE M represent the only minor point of concentration in an otherwise highly dispersed portfolio.
Based on the USPTO statutory response window for each pending office action. 20 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. 20 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 |
|---|---|
| §101 only | 2 (3%) |
| §101 + other | 9 (15%) |
| §103 only | 14 (23%) |
| §102 only | 2 (3%) |
| §112 only | 4 (7%) |
| Double-patenting + other | 12 (20%) |
| Multi-statute (no §101) | 17 (28%) |
| No statute on record | 1 (2%) |
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.
