What this shows Sichuan's Innovation Score is 42.0/100 (top 32% 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 Sichuan?

Each dot is one of Sichuan’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). Sichuan’s own 11.0 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sichuan's grants concentrate

Sichuan Xieming Technology Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2023 (3 grants) versus a trough of 2 in 2024. By volume, Sichuan sits between SiGe Semiconductor, Inc. and Siemens Heathcare GmbH.

Sichuan's three-year grant acceleration

Sichuan Xieming Technology Co., Ltd. shows 5 grants in 2022–2024 against only 0 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.
