Largan Medical Co. Ltd. currently manages 3 pending office actions within the Chemistry & Materials technology area. This workload is distributed across 2 distinct art units, indicating a focused but multi-disciplinary approach to their intellectual property development. The presence of 3 distinct examiners suggests that each pending action is being handled by a different individual, which may lead to varied prosecution experiences across the portfolio.
BROWN, MADISON ELIZABETH is identified as the busiest examiner for this company, currently overseeing 1 pending office action. While this represents only a portion of the total pending actions, it highlights the specific personnel involved in the most active segments of the portfolio. The involvement of the 2 distinct art units suggests that the company's innovations in Chemistry & Materials are being evaluated under slightly different examination standards. With 1 pending action under the busiest examiner, the company must maintain consistency in its responses to ensure a cohesive patent strategy.
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.
