CYTIVA - Grogan, Tuccillo & Vanderleeden, LLP has 15 pending office actions in Chemistry & Materials against 1640 career applications. Its current docket is therefore only one part of a larger historical prosecution record.
The resolved allowance rate is 92.82%, showing a high proportion of allowances among matters that have reached resolution. The average of 4.25 office actions per allowance indicates that successful cases commonly involve repeated examination exchanges before allowance.
For practitioners, the profile suggests meaningful experience in the technology area paired with a comparatively involved prosecution path. The allowance rate supports confidence in eventual outcomes, while the action average highlights the value of budgeting for continued examination and carefully sequenced claim amendments.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 1 (7%) |
| §103 only | 3 (21%) |
| §112 only | 2 (14%) |
| Double-patenting + other | 1 (7%) |
| Multi-statute (no §101) | 7 (50%) |
