ACIST Medical Systems Inc. has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are handled by 2 distinct examiners within 1 distinct art unit. This means each action is being reviewed by a different person but within the same specialized group. The involvement of 1 distinct art unit suggests a very specific technical focus for the company's medical device filings. This concentration within a single unit allows for a more uniform understanding of the relevant examination standards.
The busiest examiner, PENG, BO JOSEPH, has 1 pending action. This is consistent with the 2 distinct examiners handling the 2 total pending office actions. With 2 distinct examiners and 1 distinct art unit, the portfolio is concentrated within a single specialized division at the USPTO. Practitioners should be prepared for different examiner perspectives while navigating the uniform standards of the single art unit involved in these Medical Devices & Mechanical Engineering matters. The lack of examiner overlap means each case will likely proceed on its own merits.
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.
