Tatsuno Corporation operates within the Medical Devices & Mechanical Engineering technology area, currently managing 3 pending office actions. These actions are split across 2 distinct art units, suggesting the portfolio covers multiple mechanical or medical disciplines. The prosecution is overseen by a group of distinct examiners that is smaller than the number of pending actions, which concentrates the workload.
CHEYNEY, CHARLES is identified as the busiest examiner for the portfolio, holding 2 pending actions. This means that multiple pending office actions are under the review of a single individual. This concentration requires the company to closely monitor the specific preferences and rejection patterns of CHEYNEY, CHARLES, as his decisions impact multiple active matters.
The presence of 3 pending office actions indicates the current level of activity at the patent office. This structure creates a focused prosecution environment where individual examiner relationships are highly significant. The current activity level reflects a specific set of challenges within the Medical Devices & Mechanical Engineering sector.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
