Dyson Technology Limited has 90 pending office actions in Medical Devices & Mechanical Engineering. The docket spans 68 distinct examiners and 30 distinct art units, combining broad examiner distribution with a more concentrated technical allocation. This pattern suggests that multiple related matters may be progressing within recurring mechanical and device-oriented examination groups.
YUEN, JESSICA JIPING is the busiest examiner, with 8 pending matters. That concentration makes the examiner a useful focal point for reviewing recurring objections, amendment positions, and interview practices, while the wider examiner base still requires matter-specific monitoring. Art-unit coordination may help identify common technical or claim-treatment patterns.
Based on the USPTO statutory response window for each pending office action. 18 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. 18 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 | 5 (6%) |
| §103 only | 32 (36%) |
| §102 only | 2 (2%) |
| §112 only | 1 (1%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 4 (5%) |
| Multi-statute (no §101) | 43 (49%) |
