What this shows Leach's Innovation Score is 39.8/100 (top 37% 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 Leach?

Each dot is one of Leach’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). Leach’s own 17.3 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Leach's grants concentrate

Leach International Corporation is a focused PatentsView assignee: 7 CPC subclasses with 50% of grants classified under H02H (Emergency Protective Circuit Arrangements). By volume, Leach sits between LC Therapeutics Inc. and Lediamond Opto Corporation.

Leach's three-year grant acceleration

Leach International Corporation shows 2 grants in 2022–2024 against only 1 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.
