Ray Quinney & Nebeker, representing Marathon Petroleum, handles Chemistry & Materials matters and has 5 pending office actions. The portfolio reports 309 career applications, a resolved allowance rate of 97.7%, and an average of 2.34 office actions per allowance.
The allowance rate indicates that nearly all resolved applications reached allowance within the reported portfolio. The office-action average shows that allowed matters generally required more than two examination actions, indicating continued prosecution activity even alongside the high allowance outcome.
The pending docket is small compared with the career application volume. For chemistry and materials practitioners, the figures offer a historical basis for considering both favorable allowance results and the response effort associated with reaching allowance, without predicting any particular pending matter.
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 (20%) |
| Multi-statute (no §101) | 4 (80%) |
