Gea Mechanical Equipment GmbH has 2 pending office actions in Chemistry & Materials. Both matters are assigned to 1 distinct examiner and 1 distinct art unit, indicating concentration within a single examination path. Counsel can coordinate the pending responses around that shared examiner and unit while checking each action for its individual claim and procedural issues.
LIU, SHUYI S is the busiest examiner, with 2 pending matters. The examiner accounts for the full identified activity, making consistency across the responses a practical consideration. Counsel can compare the chemistry and materials issues, align compatible arguments, and preserve distinctions where the two actions address different claim features.
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.
