What this shows Huaiyin's Innovation Score is 45.0/100 (top 24% 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 Huaiyin?

Each dot is one of Huaiyin’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). Huaiyin’s own 6.7 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Huaiyin's grants concentrate

Huaiyin Institute OF Technology is a focused PatentsView assignee: 13 CPC subclasses with 30% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2018. By volume, Huaiyin sits between Hokuriku Electric Industry Co., Ltd. and Hydac Accessories GMBH.

Huaiyin's three-year grant acceleration

Huaiyin Institute OF Technology shows 7 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.
