Clifford Chi, A.P.C. has 60 pending office actions in Medical Devices & Mechanical Engineering and a career record of 1727 applications. The profile therefore combines an active current docket with a substantial application history in a technical area where device and mechanical issues may intersect.
The resolved allowance rate is 90.74%, and the average is 1.51 office actions per allowance. These figures show that resolved matters frequently reached allowance and, on average, did so after fewer office actions than the profile’s allowance rate alone would indicate. For prosecution planning, the pending docket signals immediate activity, while the historical measures provide context for response sequencing and expected examination interaction.
Based on the USPTO statutory response window for each pending office action. 20 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. 20 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 only | 3 (5%) |
| §101 + other | 2 (3%) |
| §103 only | 21 (36%) |
| §102 only | 3 (5%) |
| §112 only | 5 (8%) |
| Double-patenting only | 1 (2%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 23 (39%) |
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.
