Bfkw LLC maintains a patent portfolio in the Medical Devices & Mechanical Engineering technology area with 5 pending office actions. These actions are handled by 2 distinct examiners, indicating a concentration of the workload among a small number of individuals. All 5 pending office actions are situated within 1 distinct art unit, which suggests a narrow technical focus for the portfolio.
CHENG FONG YANG is the busiest examiner for this portfolio, overseeing 4 pending office actions. This represents the vast majority of the portfolio's 5 pending office actions, leaving only 1 action for the other distinct examiner. Such a high concentration of 4 pending actions with a single examiner, CHENG FONG YANG, means that this individual's examination style will significantly impact the portfolio's outcomes.
The focus on 1 distinct art unit for all 5 pending office actions implies that the subject matter is highly specialized within the Medical Devices & Mechanical Engineering field. Practitioners should note that CHENG FONG YANG is responsible for 4 of the 5 pending actions, making this examiner the primary point of contact for the portfolio's current prosecution. This high level of concentration with 2 distinct examiners in 1 art unit allows for a targeted prosecution strategy.
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 | 1 (20%) |
| Multi-statute (no §101) | 4 (80%) |
