What this shows Weichai's Innovation Score is 54.4/100 (top 8% 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 Weichai?

Each dot is one of Weichai’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). Weichai’s own 12.8 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Weichai's grants concentrate

Weichai Power Co., Ltd. is a focused PatentsView assignee: 34 CPC subclasses with 56.6% of grants classified under Y02T (Climate Change Mitigation Technologies Related TO Transportation). Peak complete grant year is 2021 (13 grants) versus a trough of 1 in 2015. By volume, Weichai sits between Veoneer Sweden AB and Zoho Corporation Private Limited.

Weichai's three-year grant acceleration

Weichai Power Co., Ltd. shows 26 grants in 2022–2024 against only 14 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.
