Sunflower Therapeutics, PBC is currently addressing 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These 2 actions are split between 2 distinct examiners and 2 distinct art units. LING, FOR K. is the busiest examiner, with 1 pending office action. This distribution means each of the 2 pending matters is being reviewed by a different examiner in a different art unit, requiring separate prosecution strategies.
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 |
