What this shows Diamond's Innovation Score is 46.0/100 (top 22% 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 Diamond?

Each dot is one of Diamond’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). Diamond’s own 7.3 claims/patent is at or below the 11.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Diamond's grants concentrate

Diamond & Zebra Electric MFG. Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under F02P (Ignition, Other Than Compression Ignition, FOR Internal-combustion ENGINES; Testing OF Ignition Timing IN Compression-ignition Engines). Peak complete grant year is 2023 (4 grants) versus a trough of 2 in 2024. By volume, Diamond sits between DE Grisogono S.A. and DK City Corporation.

Diamond's three-year grant acceleration

Diamond & Zebra Electric MFG. Co., Ltd. shows 9 grants in 2022–2024 against only 0 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.
