Bwt Holding GmbH is active in the Chemistry & Materials technology area with 3 pending office actions. These actions are distributed across 3 distinct examiners, showing a lack of examiner overlap in the current portfolio. Despite the number of examiners, the work is contained within 2 distinct art units. DRODGE, JOSEPH W is the busiest examiner, though they only account for 1 pending office action.
This distribution suggests that the 3 pending office actions are spread evenly among the 3 distinct examiners. The use of 2 distinct art units indicates that while the technology is within a single broad area, it touches on different sub-specialties. For a practitioner, this means preparing for different examination styles across the 3 pending office actions. The diversity of examiners relative to the 3 pending actions suggests that no single examiner's tendencies will dominate the portfolio's overall success. Because DRODGE, JOSEPH W has 1 pending office action, the workload is balanced across the 3 distinct examiners and 2 distinct art units.
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.
