MacMillan, Sobanksi & Todd, LLC - Cook Medical specializes in the Medical Devices & Mechanical Engineering technology area, managing 396 career applications. The firm has a resolved allowance rate of 84.4 percent. This 84.4 percent allowance rate shows a consistent ability to obtain patent grants within the medical device sector.
The firm averages 4.65 office actions per allowance. This figure of 4.65 office actions suggests an extensive prosecution process, often requiring multiple rounds of communication with examiners to reach an allowance. Currently, the firm is managing 10 pending office actions. These 10 pending office actions are part of the firm's ongoing work across its 396 career applications. The data indicates that while the firm maintains a solid 84.4 percent allowance rate, it frequently engages in detailed and persistent negotiations with the patent office to secure intellectual property for its clients.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 |
|---|---|
| §103 only | 5 (33%) |
| §102 only | 1 (7%) |
| Double-patenting only | 1 (7%) |
| Double-patenting + other | 2 (13%) |
| Multi-statute (no §101) | 6 (40%) |
