Diehl Brass Solutions Stiftung & Co. Kg is currently managing 3 pending office actions in the Chemistry & Materials technology area. These actions are handled by 2 distinct examiners across 2 distinct art units. WALCK, BRIAN D is the busiest examiner, responsible for 2 pending office actions. This concentration means that 2 of the company's 3 pending office actions are being reviewed by a single examiner, making WALCK, BRIAN D a central figure in the company's current prosecution efforts.
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.
