What this shows Sinochem's Innovation Score is 29.9/100 (32nd percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Sinochem?

Each dot is one of Sinochem’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Sinochem’s own 12.8 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sinochem's grants concentrate

Sinochem Lantian Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 33.3% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Sinochem sits between Sidel Engineering & Conveying Solutions and Sitecore Corporation A/S.

Sinochem's three-year grant acceleration

Sinochem Lantian Co., Ltd. shows 3 grants in 2022–2024 against only 5 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
