Erich Windhab has 1 pending office action in the Chemistry & Materials technology area. This action is assigned to 1 distinct examiner and is located within a single distinct art unit. LEFF, STEVEN N is the busiest examiner for this portfolio.
Because there is only a single pending office action, the busiest examiner is responsible for the entire pending workload. The presence of a sole distinct examiner and a sole distinct art unit for this action indicates a very specific point of contact within the patent office. This ratio between pending matters and examiners suggests that the prosecution is highly concentrated.
Practitioners should focus on the specific requirements of the assigned art unit. The Chemistry & Materials designation provides the technical context for this pending matter. This concentration suggests that the examiner's individual preferences will be the primary factor in the outcome of the case.
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.
