Cardiacassist Inc. is managing 5 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 5 distinct examiners, which means that every active case is being reviewed by a different individual. The portfolio spans 2 distinct art units, indicating some technical breadth within the medical and mechanical fields. This distribution across 5 distinct examiners and 2 distinct art units suggests a highly decentralized prosecution strategy for the company's 5 pending office actions.
The workload is evenly spread, as the busiest examiner, CHATRATHI, ARJUNA P, is responsible for 1 pending office action. This represents 1 of the total 5 pending office actions. With 5 distinct examiners and 2 distinct art units, the company's prosecution is highly decentralized. This variety of reviewers suggests that the company's 5 pending office actions are receiving a wide range of independent evaluations across the 2 specialized units. Practitioners must manage 5 separate examiner relationships, which provides multiple opportunities for success but requires a diverse set of legal strategies tailored to each of the 5 distinct examiners.
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.
