Hd Construction Equipment Co. Ltd. has 4 pending office actions in Transportation, E-Commerce & Mechanical Systems. The matters involve 4 distinct examiners and 4 distinct art units. LEGGETT, ANDREA C. is the busiest examiner, with 1 pending action.
The matching counts indicate separate examiner and technical-unit paths for the pending matters. Counsel should manage responses independently while reviewing the portfolio for consistent treatment of equipment terminology, functional limitations, and prior-art distinctions. The LEGGETT assignment is one individual path rather than a repeated concentration.
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.
| Bucket | Cases |
