L'Air Liquide, Société Anonyme pour l'Etude et l'Exploitation des Procédés Georges Claude has 53 pending office actions in Medical Devices & Mechanical Engineering. The workload spans 39 distinct examiners and 22 distinct art units, showing substantial distribution with recurring assignments across the examination structure. Counsel should use centralized portfolio controls to identify common issues while preserving technical distinctions among matters.
MENGESHA, WEBESHET is the busiest examiner, with 7 pending actions. That examiner represents the clearest concentration in the profile and may justify coordinated review of shared prosecution themes. The broader spread across examiners and art units still requires separate response strategies, especially where claim language or cited references differ.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 | 1 (2%) |
| §103 only | 12 (24%) |
| §102 only | 1 (2%) |
| §112 only | 6 (12%) |
| Double-patenting + other | 2 (4%) |
| Multi-statute (no §101) | 26 (53%) |
| 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.
