Sumitomo Bakelite Co., Ltd. currently has 17 pending office actions in the Medical Devices & Mechanical Engineering technology area. These 17 actions are assigned to 15 distinct examiners, showing that most applications are being reviewed by different individuals. The portfolio is distributed across 7 distinct art units, indicating a variety of technical focuses within the mechanical and medical device sectors. This distribution across 7 distinct art units requires the company to manage several different administrative groups at the USPTO.
Casey George Cha is the busiest examiner for the company, overseeing 2 pending office actions. This leaves the other 15 pending office actions to be handled by other distinct examiners. The presence of 7 distinct art units for 17 actions suggests that the company's technology is spread across several specialized groups. This ratio of 15 distinct examiners to 17 pending office actions means the company must manage many different individual examination styles simultaneously. Practitioners should prepare for varied feedback across the Medical Devices & Mechanical Engineering portfolio.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 | 7 (41%) |
| Double-patenting + other | 1 (6%) |
| Multi-statute (no §101) | 9 (53%) |
