Cidra Corporate Services LLC currently manages 3 pending office actions within the Chemistry & Materials technology area. These matters are assigned to 3 distinct examiners, reflecting a distributed prosecution strategy across the company's current filings. The portfolio's activity is situated within 3 distinct art units, which suggests the underlying technology is diverse in its technical classification within the chemistry sector.
Van Sell, Nathan L is the busiest examiner for the company, currently overseeing 1 pending office action. This specific workload accounts for 1 of the 3 total pending actions for the portfolio. With 3 examiners and 3 art units involved, the prosecution process is spread across multiple patent office divisions. Practitioners should focus on the specific requirements of these different units, as their individual decisions will define the immediate success of the company's intellectual property efforts. This distribution requires a coordinated approach to ensure consistency across the 3 pending matters.
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.
| Bucket | Cases |
