4 pending office actions • 2 art units • 3 examiners • 0 of 4 (0%) have an AI response strategy ready
Xefco Pty Ltd. has 4 pending office actions in Chemistry & Materials. The portfolio includes 3 distinct examiners and 2 distinct art units, showing that some examination resources handle multiple matters or that assignments overlap within the technical area.
CHEN, KEATH T is the busiest examiner, with 2 pending matters. That concentration makes this examiner relationship the clearest coordination point in the profile. Counsel should compare the two matters for recurring claim issues, cited art, and response positions, while separately accounting for the other examiner and art-unit assignments.
Based on the USPTO statutory response window for each pending office action. 4 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 4 of the docket's apps have a known mailing date.
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.
