MATTHEWS INTERNATIONAL Corporation has 18 pending office actions in the Chemistry & Materials technology area. The prosecution is decentralized, involving 18 distinct examiners across 12 distinct art units. This distribution of examiners and pending actions indicates that every single case is being handled by a different individual, which can lead to significant variance in prosecution timelines and success rates across the portfolio. Practitioners must prepare for 18 different sets of examiner preferences and 12 different art unit standards.
TRINH, MINH N is the busiest examiner, though they currently handle only 1 pending office action. With 12 distinct art units involved, the company's technology likely spans a wide array of chemical and material science sub-specialties. This diversity requires counsel to maintain expertise across a dozen different art unit environments. The lack of examiner overlap means there are few opportunities to leverage successful arguments from one case to another, as each of the 18 pending office actions is subject to a unique examiner's perspective. Success in the Chemistry & Materials sector will require a highly customized approach for each of the 18 pending office actions.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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.
| Bucket | Cases |
|---|---|
| §101 + other | 2 (12%) |
| §103 only | 4 (24%) |
| §102 only | 1 (6%) |
| §112 only | 1 (6%) |
| Double-patenting + other | 1 (6%) |
| Multi-statute (no §101) | 8 (47%) |
