Tate & Lyle Solutions Usa LLC is managing 4 pending office actions within the Chemistry & Materials technology area. These actions are distributed among 4 distinct examiners, meaning each examiner is currently reviewing 1 case for the company. The prosecution is split across 2 distinct art units, indicating some technical concentration despite the number of examiners involved in the current filings.
LANKFORD JR, LEON B is the busiest examiner for the portfolio, with 1 busiest examiner pending office action. This figure is consistent with the other distinct examiners, as the 4 total pending office actions are spread evenly. The involvement of 4 distinct examiners across only 2 distinct art units suggests that the company is navigating multiple reviews within a limited set of technical groups. This structure requires the company to manage 4 separate examiner interactions while addressing the technical requirements of the 2 distinct art units involved in the current prosecution.
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.
