Law Office of Michael Chen has 48 pending office actions in Medical Devices & Mechanical Engineering and 3393 career applications. The profile shows a substantial current examination workload together with the largest supplied historical application record for this practice.
The resolved allowance rate is 91.25%, and the average is 1.45 office actions per allowance. These figures indicate both the proportion of resolved matters reaching allowance and the examination activity associated with allowed matters. Practitioners can use the combination to anticipate response volume and evaluate prosecution patterns, while recognizing that historical performance does not determine the result of an individual pending application.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 (9%) |
| §103 only | 12 (26%) |
| §102 only | 1 (2%) |
| §112 only | 5 (11%) |
| Double-patenting + other | 3 (7%) |
| Multi-statute (no §101) | 20 (43%) |
| No statute on record | 1 (2%) |
