L'Air Liquide, Société Anonyme pour l'Etude et l'Exploitation des Procédés Georges Claude maintains a substantial presence in the patent office with 64 pending office actions. These actions are concentrated within the Medical Devices & Mechanical Engineering technology area. The prosecution of these matters is highly distributed, involving 40 distinct examiners across 19 distinct art units. This breadth suggests a complex portfolio that requires managing a wide variety of examiner preferences and art unit specificities.
MOORE, DEVON TYLEN is identified as the busiest examiner for the company, currently overseeing 7 pending office actions. While 40 distinct examiners are involved in the portfolio, the concentration of 7 actions under a single examiner represents a significant point of focus for the applicant's legal team. Practitioners must balance the broad requirements of 19 distinct art units with the specific tendencies of high-volume examiners like MOORE, DEVON TYLEN.
The ratio of 64 pending office actions to 40 distinct examiners indicates that while many examiners handle only one matter, others manage multiple files. This structure allows for some consistency in prosecution strategy across certain segments of the portfolio while still requiring a broad-based approach to address the 19 distinct art units involved. Managing 64 pending actions in a single technology area like Medical Devices & Mechanical Engineering highlights the company's intensive investment in this specific field.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 (18%) |
| §102 only | 1 (2%) |
| §112 only | 11 (17%) |
| Double-patenting + other | 4 (6%) |
| Multi-statute (no §101) | 37 (56%) |
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.
