Sartorius Stedim Fmt SAS has 2 pending office actions within the Chemistry & Materials technology area. These actions are distributed across 2 distinct examiners and the same number of distinct art units. This distribution indicates that each pending matter is being handled by a different examiner in a different department, which may lead to varying prosecution timelines.
LAN, YAN is the busiest examiner for the portfolio, currently responsible for 1 pending office action. This means that the other pending action is assigned to a different examiner. The Chemistry & Materials area often requires specialized knowledge, and the involvement of multiple examiners and art units suggests a diverse range of subject matter in the company's filings.
With the total pending office actions spread across the distinct art units, the company must manage its prosecution strategy to ensure consistency. Although LAN, YAN is the busiest examiner with 1 action, the overall workload is split between the examiners. Practitioners should monitor the distinct examiners to identify any specific requirements or trends that could affect the outcome of the total pending matters.
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.

| §103 only | 1 (50%) |
