4 pending office actions • 3 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready
Puzzle Medical Devices Inc. has 4 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 4 distinct examiners. This means that each of the 4 pending office actions is being reviewed by a different individual.
The portfolio is active across 3 distinct art units. SHENG, CHAO is the busiest examiner, with 1 busiest examiner pending action. This indicates a decentralized prosecution landscape where no single examiner holds a majority of the workload.
For practitioners, the presence of 4 distinct examiners and 3 distinct art units in the Medical Devices & Mechanical Engineering sector requires a diversified strategy. Each of the 4 pending office actions must be managed according to the specific standards of the 3 distinct art units and the individual examiners. The role of SHENG, CHAO as the busiest examiner with 1 busiest examiner pending action underscores this distribution.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
