Intersurgical AG manages 4 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 2 distinct art units and involve 4 distinct examiners. ZIEGLER, MATTHEW D is the busiest examiner for the company, currently handling 1 pending office action. The distribution of these matters among 4 distinct examiners shows that every active action is assigned to a different individual.
The 2 distinct art units suggest a concentrated technical focus within the company's medical devices portfolio. ZIEGLER, MATTHEW D is responsible for 1 pending office action, which is a single component of the company's total pending workload. This 4 to 4 ratio of pending office actions to distinct examiners indicates that no single examiner has a dominant influence over the current portfolio. Practitioners can expect to interact with 2 distinct art units, reflecting the technical classifications of the matters currently under review.
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.
