Yonwoo Co., Ltd. currently manages 5 pending office actions within the Medical Devices & Mechanical Engineering technology area. This portfolio is distributed across 5 distinct examiners, indicating an examination process where no official handles a majority of the workload. The 3 distinct art units involved suggest that the company's innovations span multiple specialized classifications within the patent office, requiring an understanding of different examination standards.
Michael Christopher Patterson is identified as the busiest examiner for this portfolio, though he is currently responsible for 1 pending action. This distribution means that prosecution strategies must be tailored to the individual tendencies of 5 different examiners rather than a centralized group. The presence of 5 pending actions across 3 art units highlights a range of mechanical and medical engineering subject matter currently under review. Practitioners should note that the lack of examiner concentration may lead to varied outcomes across the portfolio, as each of the 5 examiners will apply their own interpretation of the prior art.
With 5 pending office actions, the company maintains a level of activity within the USPTO. The involvement of 3 distinct art units further implies that the company's research and development efforts are spread across several mechanical disciplines. Navigating this landscape requires a flexible approach to prosecution, as the 5 distinct examiners may have differing views on patentability and claim scope.
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.
