ACIST Medical Systems Inc. currently has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These 2 actions are being handled by 2 distinct examiners in 2 distinct art units. This indicates a complete lack of overlap in the current prosecution of the company's patent applications.
PENG, BO JOSEPH is the busiest examiner with 1 pending office action. With only 2 pending office actions total, the company's current activity at the USPTO is minimal. Practitioners must prepare for two separate examination processes, as the 2 distinct examiners and 2 distinct art units mean that each case will be decided on its own specific technical and procedural merits without influence from the other. This decentralized structure requires practitioners to be versatile, adapting to the specific feedback of 2 different examiners. Since there is no concentration in a single art unit, the company must navigate the nuances of 2 distinct art units simultaneously. Every pending office action represents a significant portion of the company's active portfolio, making each interaction with the 2 distinct examiners highly consequential for the firm's overall intellectual property position in the Medical Devices & Mechanical Engineering sector.
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.
