MAKITA Corporation manages 52 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 17 distinct art units, reflecting a broad range of mechanical and tool-related innovations. With 43 distinct examiners involved in these 52 cases, the company faces a high degree of examiner variety, as most of their pending matters are being reviewed by different individuals.
CHUKWURAH, NATHANIEL C is the busiest examiner for this portfolio, currently overseeing 4 pending office actions. This examiner's workload represents a small but notable portion of the 52 total pending actions. For the company, the feedback from CHUKWURAH, NATHANIEL C is important, but the overall prosecution strategy must account for the 43 distinct examiners who are active across the portfolio.
The presence of 17 distinct art units for 52 pending office actions suggests that the company's technology is quite diverse within the Medical Devices & Mechanical Engineering sector. Because the work is spread among 43 distinct examiners, the company must manage many different individual styles and interpretations. With 4 actions assigned to CHUKWURAH, NATHANIEL C, the remaining actions are distributed among other examiners, requiring a highly adaptable approach to patent prosecution.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 |
|---|---|
| §103 only | 15 (29%) |
| §102 only | 10 (19%) |
| Double-patenting only | 1 (2%) |
| Multi-statute (no §101) | 26 (50%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
