Kulzer GmbH has 2 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 2 distinct art units. The prosecution involves 2 distinct examiners. SULTANA, NAHIDA is the busiest examiner with 1 pending office action. With 2 pending office actions and 2 distinct examiners, each examiner is responsible for one case.
This distribution across 2 distinct art units indicates that the company's materials filings are being reviewed by different personnel. Practitioners should focus on the specific requirements of the 2 distinct art units while tailoring their arguments to the 2 distinct examiners. The presence of 2 pending office actions requires a consistent technical narrative to be maintained across both cases. This structure allows for individual attention to each application within the Chemistry & Materials sector.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
