What this shows Clover's Innovation Score is 31.9/100 (39th 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 Clover?

Each dot is one of Clover’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). Clover’s own 4.5 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Clover's grants concentrate

Clover MFG. Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 21.6% of grants classified under D05B (Sewing). Peak complete grant year is 2018 (10 grants) versus a trough of 1 in 2023. By volume, Clover sits between Bauer Maschinen GmbH and Children's Hospital & Research Center at Oakland.

Clover's three-year grant acceleration

Clover MFG. Co., Ltd. shows 6 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.
