Corning Incorporated manages 209 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 49 distinct art units, reflecting a broad and diverse technical portfolio. The prosecution involves 131 distinct examiners, which indicates that many examiners are handling more than one application for the company. This ratio of 131 distinct examiners for 209 pending office actions suggests a level of examiner concentration within the portfolio.
CHU, CHRIS H is the busiest examiner for the portfolio, overseeing 11 of the 209 pending office actions. This concentration is notable, but the 131 distinct examiners still provide a range of perspectives. The 49 distinct art units suggest that the company 209 pending office actions are grouped into many technical clusters, requiring a sophisticated approach to manage consistency across the various examination groups. Practitioners should focus on the specific preferences of the busiest examiner while also managing the diverse requirements of the 49 different art units involved in the 209 pending office actions.
Based on the USPTO statutory response window for each pending office action. 51 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. 51 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 (1%) |
| §103 only | 84 (40%) |
| §102 only | 10 (5%) |
| §112 only | 6 (3%) |
| Double-patenting only | 5 (2%) |
