General Electric Company has 170 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions involve 128 distinct examiners across 61 distinct art units. The presence of 170 actions in 61 art units reflects the company's diverse engineering interests and extensive patenting activity. With 128 distinct examiners, the portfolio is relatively decentralized, though some examiners handle multiple cases.
KIM, TAE JUN is the busiest examiner for the portfolio, currently handling 7 pending actions. While 7 actions is the highest count for any single examiner, it is a small fraction of the 170 total pending office actions. This indicates that the company's workload is spread across a large number of officials, with 128 distinct examiners involved. The 61 distinct art units further underscore the technical breadth of the company's mechanical and medical filings.
For practitioners, the 170 pending office actions represent a significant volume of ongoing prosecution. TAE JUN KIM, as the busiest examiner with 7 pending actions, is a key figure, but the majority of the 128 distinct examiners handle only one or two cases. The 61 distinct art units involved require familiarity with a wide range of examination standards within the Medical Devices & Mechanical Engineering field.
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 only | 3 (2%) |
| §101 + other | 9 (5%) |
| §103 only | 61 (36%) |
| §102 only | 5 (3%) |
