What this shows Earthway's Innovation Score is 36.7/100 (top 46% 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 Earthway?

Each dot is one of Earthway’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). Earthway’s own 10.7 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Earthway's grants concentrate

Earthway Products, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 60% of grants classified under A01C (PLANTING; SOWING; Fertilising). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2016. By volume, Earthway sits between Etymotic Research, Inc. and Ellenby Technologies, Inc..

Earthway's three-year grant acceleration

Earthway Products, Inc. shows 5 grants in 2022–2024 against only 3 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.
