What this shows Eddy's Innovation Score is 42.5/100 (top 30% 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 Eddy?

Each dot is one of Eddy’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). Eddy’s own 20.4 claims/patent is ABOVE the 13.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Eddy's grants concentrate

Eddy Current Limited Partnership is a focused PatentsView assignee: 13 CPC subclasses with 87.9% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2015. By volume, Eddy sits between E-lead Electronic Co., Ltd. and Eppendorf SE.

Eddy's three-year grant acceleration

Eddy Current Limited Partnership shows 12 grants in 2022–2024 against only 15 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.
