Clearstream Technologies Limited is managing 6 pending office actions in the Medical Devices & Mechanical Engineering technology area. While these actions are distributed among 6 distinct examiners, they are all contained within 1 distinct art unit. This represents a high level of examiner diversity within a single technical department. The concentration in 1 art unit suggests that the underlying technical standards and prior art references used by the examiners may be closely related.
Davina En-Yin Lee is the busiest examiner for the company, currently responsible for 1 pending office action. Because each of the 6 examiners handles exactly 1 pending action, the company must navigate 6 different personal examination styles. This requires a strategy that balances individual examiner preferences with the unified policies of the single art unit involved. Practitioners should focus on maintaining consistent technical arguments across all 6 actions, as they are all subject to the same departmental oversight. Davina En-Yin Lee is one of the 6 individuals contributing to this diverse prosecution landscape.
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 | 2 (33%) |
