What this shows Ertec's Innovation Score is 29.4/100 (31st percentile 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 Ertec?

Each dot is one of Ertec’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). Ertec’s own 20.7 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ertec's grants concentrate

Ertec Environmental Systems is a focused PatentsView assignee: 6 CPC subclasses with 66.7% of grants classified under B01D (Separation). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2017. By volume, Ertec sits between Equals 3, Inc. and Esthetic Education LLC.

Ertec's three-year grant acceleration

Ertec Environmental Systems shows 1 grants in 2022–2024 against only 4 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.
