What this shows Echogen's Innovation Score is 39.3/100 (top 38% 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 Echogen?

Each dot is one of Echogen’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). Echogen’s own 17.1 claims/patent is ABOVE the 16.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Echogen's grants concentrate

Echogen Power Systems, LLC is a focused PatentsView assignee: 21 CPC subclasses with 93.3% of grants classified under F01K (Steam Engine PLANTS; Steam ACCUMULATORS; Engine Plants NOT Otherwise Provided FOR; Engines Using Special Working Fluids OR Cycles). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2020. By volume, Echogen sits between DWS S.R.L. and Epicentrx, Inc..

Echogen's three-year grant acceleration

Echogen Power Systems, LLC shows 1 grants in 2022–2024 against only 7 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.
