What this shows Shinda's Innovation Score is 51.9/100 (top 11% 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 Shinda?

Each dot is one of Shinda’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). Shinda’s own 9.5 claims/patent is at or below the 10.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shinda's grants concentrate

Shinda (TANGSHAN) Creative OIL & GAS Equipment Co., Ltd. is a focused PatentsView assignee: 24 CPC subclasses with 33.3% 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 2022 (4 grants) versus a trough of 1 in 2018. By volume, Shinda sits between Shenzhen Xinzengcai Creative Electronics Co., Ltd. and Sidel Engineering & Conveying Solutions.

Shinda's three-year grant acceleration

Shinda (TANGSHAN) Creative OIL & GAS Equipment Co., Ltd. shows 9 grants in 2022–2024 against only 2 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.
