Linde GmbH currently manages 22 pending office actions within the Medical Devices & Mechanical Engineering technology area. This volume of active prosecution is distributed across 11 distinct art units, indicating the technical range of the portfolio. The company interacts with 19 distinct examiners, suggesting that prosecution strategies must be tailored to a variety of individual examiner preferences and art unit practices.
The busiest examiner for this portfolio is MOORE, DEVON TYLEN, who is responsible for 4 of the pending office actions. This concentration represents a specific point of focus within the 22 total actions currently pending. Practitioners should note that while the 19 distinct examiners provide a distribution of the workload, the Medical Devices & Mechanical Engineering filings are concentrated in specific regulatory or technical subgroups.
Managing the workload across the various examiners requires coordination to ensure consistent arguments are made across the different interactions. The presence of 11 distinct art units further emphasizes the need for a multifaceted approach to patent prosecution. The 4 pending office actions assigned to MOORE, DEVON TYLEN represent the highest concentration of work under any individual examiner for this company.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 (10%) |
| §103 only | 7 (33%) |
| Multi-statute (no §101) | 12 (57%) |
