23 pending office actions • 13 clients • 20 examiners • 14 art units • 0 of 23 (0%) have an AI response strategy ready
Chen Yoshimura LLP manages 3243 career applications in the Semiconductors, Circuits & Optics technology area. The firm currently has 12 pending office actions and a resolved allowance rate of 91.18 percent.
The average of 2.57 office actions per allowance provides insight into the efficiency of the prosecution cycle. This statistic helps practitioners estimate the number of responses typically needed to reach a grant. The 91.18 percent allowance rate, when considered with the 2.57 average office actions, offers a comprehensive view of the firm's historical performance in the semiconductor and optics sectors.
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 (9%) |
| §103 only | 8 (35%) |
| §102 only | 4 (17%) |
| Multi-statute (no §101) | 9 (39%) |
How the docket's pending cases split across USPTO tech-center bands.
