Dyson Technology Limited operates in the Medical Devices & Mechanical Engineering technology area. The company currently has 90 pending office actions. These actions are distributed across 20 distinct art units. The presence of 20 distinct art units for the pending matters indicates that the company's technology is being evaluated by a wide range of specialized groups within the patent office.
The prosecution involves 73 distinct examiners. YUEN, JESSICA JIPING is the busiest examiner for the portfolio, currently managing 8 busiest examiner pending office actions. These 8 busiest examiner pending office actions represent a portion of the total workload. With 73 distinct examiners, most individuals are handling one or two matters. The 20 distinct art units and the high number of examiners create a broad prosecution landscape where the 90 pending office actions are widely dispersed across the patent office's administrative structure.
Based on the USPTO statutory response window for each pending office action. 16 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. 16 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 | 4 (4%) |
| §103 only | 28 (31%) |
| §102 only | 4 (4%) |
| §112 only | 1 (1%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 5 (6%) |
| Multi-statute (no §101) | 47 (52%) |
