What this shows Environmental's Innovation Score is 39.9/100 (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.

Where Environmental's grants concentrate

Environmental Dynamics International, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 62.5% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Environmental sits between ENK Wireless, Inc. and Epalex Corporation.

Environmental's three-year grant acceleration

Environmental Dynamics International, Inc. shows 2 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.
