Leica Biosystems Nussloch GmbH operates in the Chemistry & Materials technology area. The company has 2 pending office actions currently under review. These actions are handled by 2 distinct examiners and 2 distinct art units.
GORDON, BRIAN R is the busiest examiner, responsible for 1 pending office action. Given that there are 2 pending office actions in total, each of the 2 distinct examiners is responsible for exactly 1 action. This means the workload is evenly split between the assigned personnel.
The involvement of 2 distinct art units suggests that the pending applications cover different technical niches within the broader technology area. With 2 pending office actions, the portfolio is currently in a low-volume phase of prosecution. Practitioners should treat each action as an independent matter since they are handled by different examiners in different units. This decentralized approach across 2 distinct examiners ensures that individual case outcomes are not overly dependent on a single person's interpretation of the 2 distinct art units, including GORDON, BRIAN R.
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 (33%) |
