Daicel Miraizu Ltd. is currently prosecuting a portfolio in the Chemistry & Materials technology area. There are 2 pending office actions across the portfolio, which are being handled by 2 distinct examiners. This distribution suggests that each pending matter is receiving attention from a different official. The workload is distributed across 2 distinct art units, indicating that the applicant is pursuing innovations in different specialized fields within the chemistry sector.
CAI, WENWEN is the busiest examiner for this applicant, with 1 pending office action currently assigned. Since there are 2 pending office actions in total, the remaining 1 action is managed by the other of the 2 distinct examiners. This spread across 2 distinct art units and 2 examiners requires a strategy that accounts for different examiner styles. The 2 pending office actions represent the current hurdle for Daicel Miraizu Ltd. as it seeks to expand its intellectual property holdings in the Chemistry & Materials space. Each of the 2 distinct art units will provide a unique examination environment for these applications.
Based on the USPTO statutory response window for each pending office action. 1 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.
