What this shows Meishan's Innovation Score is 24.4/100 (15th 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 Meishan?

Each dot is one of Meishan’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). Meishan’s own 6.5 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Meishan's grants concentrate

Meishan Crrc Fastening System Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under B21J (FORGING; HAMMERING; Pressing METAL; RIVETING; Forge Furnaces). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Meishan sits between Medstreaming, Inc. and Memc Electronic Materials S.P.A..

Meishan's three-year grant acceleration

Meishan Crrc Fastening System Co., Ltd shows 2 grants in 2022–2024 against only 3 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.
