Hach Lange GmbH currently manages 7 pending office actions within the Chemistry & Materials technology area. These actions are distributed across 7 distinct examiners, meaning every pending matter is being reviewed by a different individual. This distribution requires the company to manage 7 unique examiner relationships simultaneously, which can lead to varied prosecution outcomes across the portfolio.
The portfolio spans 4 distinct art units, which is fewer than the 7 pending office actions. This ratio suggests that while the examiners are all different, some of the matters share technical classifications within the patent office. The busiest examiner is PEREZ-GUZMAN, CARLOS GABRIEL, who is responsible for 1 pending office action.
With 7 distinct examiners involved, there is no concentration of workload under any single individual, as the busiest examiner only handles 1 pending action. This represents a small fraction of the total 7 pending office actions. Practitioners should expect a variety of examination approaches across the 4 distinct art units involved in these filings, as no single unit or examiner dominates the current pending queue.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 + other | 2 (29%) |
| §103 only | 2 (29%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 2 (29%) |
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.
