BorgWarner Inc. currently manages 28 pending office actions in the Semiconductors, Circuits & Optics technology area. These actions are distributed among 27 distinct examiners and 13 distinct art units. CHANG, MINKI is the busiest examiner, holding 2 busiest examiner pending actions. The 13 distinct art units show that the company's electronic and optical innovations are reviewed by several technical groups.
With 27 distinct examiners for the 28 pending office actions, nearly every case is being handled by a unique individual. This distribution means the company must navigate various individual examiner styles and interpretations across the 13 distinct art units. The 2 busiest examiner pending actions assigned to CHANG, MINKI represent a portion of the 28 pending office actions. Practitioners should coordinate across the 27 distinct examiners to ensure consistent prosecution outcomes.
The 13 distinct art units suggest that the portfolio touches on several specialized groups within the USPTO. Managing 28 pending office actions across these units requires an understanding of the specific technical standards applied by each group. Because the 27 distinct examiners are spread across 13 distinct art units, there is variety in the technical scrutiny applied to the applications. This structure requires a strategy that accounts for both individual examiner preferences and art unit trends.
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 | 1 (4%) |
| §103 only | 8 (29%) |
| §102 only | 2 (7%) |
| Multi-statute (no §101) | 17 (61%) |
