Cantor Colburn LLP - Otis Elevator focuses on the Transportation, E-Commerce & Mechanical Systems technology area, drawing on the firm's record of 74190 career applications. This specific profile is currently managing 32 pending office actions, which indicates an active prosecution pipeline. The firm's long-standing presence in the patent system is reflected in its total application count, providing a reservoir of experience.
The firm achieves a resolved allowance rate pct of 88.07, showing success in obtaining patent grants for its clients. This performance is reached with an avg_office_actions_per_allowance of 3.16, suggesting an efficient path through the USPTO examination process. The 88.07 resolved allowance rate pct reflects the firm's effectiveness in the Transportation, E-Commerce & Mechanical Systems field. With 74190 career applications as a foundation, the 3.16 avg_office_actions_per_allowance provides a clear expectation for the duration of the prosecution cycle. These metrics together illustrate an experienced patent practice that consistently delivers results.
Based on the USPTO statutory response window for each pending office action. 12 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. 12 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 | 1 (2%) |
| §101 + other | 3 (6%) |
| §103 only | 16 (33%) |
| §102 only | 1 (2%) |
| §112 only | 1 (2%) |
| Multi-statute (no §101) | 26 (54%) |
